Is 2ml of Testosterone a Week Enough to Build Muscle? Study Results Testosterone is a hormone that plays many roles in the body, like building muscle, increasing strength, sexual health, and overall well-being. People wonder how much testosterone is needed to achieve these benefits, especially when considering testosterone replacement therapy (TRT) for muscle growth. Those with low testosterone might be considering TRT to feel better. But figuring out the right testosterone dose to use is tricky because it depends on your age, health, diet, exercise program, and how your body reacts to the treatment. In this article we will be looking at a study by Dr. Bhasin and his colleagues in 2001 published in the American Journal of Physiology and Endocrinology Metabolism. Their study was to see how different amounts of testosterone affect young men and what’s the best dose for different results. By going through what they found out we can learn a lot about what’s the right amount of testosterone for getting stronger or building muscle. Watch video here: What is the Optimal Testosterone Dose? Testosterone and Muscle Growth Testosterone is a hormone that plays a big role in muscle growth and development. Produced mainly in the testicles in men, testosterone is responsible for the development of male characteristics, including muscle mass and strength. As men age, their testosterone levels decline naturally, which can lead to a decrease in muscle mass and strength. This decline can affect overall health and well-being, so it’s important to understand the connection between testosterone and muscle growth. For those who want to build muscle, maintaining optimal testosterone levels is crucial. Testosterone stimulates protein synthesis, which is the process by which the body repairs and builds muscle tissues. Higher testosterone levels can increase muscle mass, strength, and overall health. By understanding how testosterone affects muscle growth, you can make informed decisions about your fitness and health goals. Testosterone Replacement Therapy (TRT) for Muscle Growth Testosterone Replacement Therapy (TRT) is a treatment for those with low testosterone. TRT involves injecting, gelling, or patching testosterone to restore normal testosterone levels. This is especially good for those experiencing symptoms of low testosterone such as decreased muscle mass, fatigue, and decreased libido. TRT can increase muscle mass and strength, bone density, and overall health. By restoring testosterone levels, TRT supports the body’s natural ability to build muscle and perform physically. But please note that TRT should only be done under the guidance of a doctor. While TRT can be beneficial, it also has side effects and risks, like increased red blood cell production and changes in cholesterol levels. So medical supervision is necessary to ensure safe and effective treatment. The Study In the study, about 65 young men around 25 years old and in good shape were studied. The study also included 1 ml of testosterone as part of the dosage variations. First they stopped their bodies from making testosterone naturally by giving them a drug that blocks testosterone. Then for 20 weeks they gave these men shots of a type of testosterone called cypionate once a week. The dose varied from 25 milligrams to 600 milligrams a week. By doing this, they could see how different doses affect different things. Testosterone Dose and Hormone Levels The study found a correlation between the dose of testosterone and the levels of different hormones in the body. They looked at total testosterone, free testosterone, LH (luteinizing hormone), SHBG (sex hormone-binding globulin), and IGF-1 (insulin-like growth factor 1). Here’s what they found out: As the dose of testosterone increased, so did the total testosterone levels in the body. At the beginning, the subjects had testosterone levels of 500-600 ng/dL. By week 16, those who got higher doses (300-600 mg/week) had levels of 1300-2300 ng/dL. Even with a smaller dose of 125 mg/week, the subjects had levels near what they started with. So taking around 100-125 mg/week might be enough for young men to get their testosterone back to normal. Free testosterone: Just like total testosterone, as more was given, free testosterone increased. So more dosage means more free testosterone is available in your system. LH and SHBG: The more testosterone you take, the lower these levels go. As people increase their dose of testosterone, they see a drop in LH and also in SHBG. So taking more testosterone can slow down LH production and decrease SHBG. So more free testosterone is available for your body to use. Testosterone dosage for muscle growth and body composition The study looked into how different doses of testosterone affect muscle building, muscle size, and body composition. They used various methods to measure lean muscle mass (fat-free mass) and body fat. Here’s what they found out: For fat-free mass, the study found that 100-125 mg of testosterone per week helped people gain muscle without fat. Those who took these doses had less body fat and more muscle. Even more (300-600 mg/week) gave better results in gaining muscle without fat. But the smallest doses (25-50 mg/week) didn’t do much; sometimes they even added fat. For body fat, it seems that higher doses help reduce it. Those who got 100-125 mg per week lost body fat. Those who got very low doses (25-50 mg/week) didn’t lose weight or might have added body fat. So high levels of this hormone can make you leaner by cutting down fatty tissues while increasing muscle growth. Factors to Consider in Testosterone Dosage Determining the right testosterone dosage for TRT involves considering age, health status, and individual goals. Age is a big factor, as older men may need different dosages than younger men due to natural hormonal decline. Men with underlying health conditions such as cardiovascular disease or metabolic disorder may need customized dosages to ensure safety and effectiveness. Individual goals also matter in determining testosterone dosage. For example, someone looking to improve overall health may need a different dosage than someone looking to gain massive muscle and bodybuilding. Personalized treatment plans are necessary to address these individual needs and goals. Working with a doctor is key to determining the right dosage. Regular blood tests and monitoring can help adjust the dosage as needed to keep testosterone levels within normal range. By considering these factors and working with a medical professional, you can get the best out of your TRT. Testosterone Dose and Sexual Function and Libido The study also looked into how different doses of testosterone affect sexual function and desire. To find out they asked participants to fill out questionnaires about their sex life and how much they wanted sex. Here’s what they found out: For sexual activity, the study didn’t show much change in how often people were sexually active when they took more testosterone. The frequency of sexual encounters remained the same across all doses. Note that there were not many participants in this study, so this might have affected the results. For libido, it was found that 300-600 mg/week of testosterone gave a slight increase in desire. But 25-125 mg/week didn’t make much of a difference in libido. So higher doses used by bodybuilders might be more effective in increasing sexual desire. No Change in Cognitive Function In the study they also looked into how well people can think and remember. But even with different doses of testosterone, there was no big change in brain function. Note that this study was done on young guys. To know if testosterone affects thinking and memory in older men more studies need to be done. Testosterone Dose and Strength and Power In the study they tested the strength and power of participants’ legs by having them do leg press for 20 weeks. What they found out was interesting—the amount of testosterone given to the participants made a difference in how much stronger or more powerful their legs became. Those who got 300-600 mg/week had a significant increase in strength and power of their legs. So taking higher doses of testosterone can make you stronger and more powerful even if you don’t work out. Hemoglobin, Hematocrit and Cholesterol Levels Giving testosterone changes blood counts and fat levels in the body. The results match what we already know: Hemoglobin: As testosterone dose increased, so did hemoglobin levels. So as more testosterone is given more hemoglobin goes up. This means treatment with testosterone can affect erythropoiesis, which is how our body makes red blood cells. Just like hemoglobin, when testosterone doses go up, so does hematocrit. Hematocrit is all about how much space red blood cells take up in our blood. The study didn’t specify what’s the ideal level of hematocrit is, but note that too much can be bad for your heart health. Lipid Profile: The administration of testosterone caused a fluctuation in the levels of HDL cholesterol, the beneficial type. When you have more testosterone in your system, your HDL cholesterol tends to decrease. So it’s really important to monitor lipid profiles if you’re on testosterone therapy. Conclusion In 2001 Dr. Bhasin and his team did a study that looked into how different doses of testosterone affect several factors. Although the study was done on young men and had a small number of participants, it still gives us valuable information on how testosterone levels relate to muscle size, sexual health, brain function, physical strength, and blood-related measures. According to the study, 100-125 mg/week may be enough for young men to get their testosterone levels back to normal. For bodybuilding, 300-600 mg/week seems to increase muscle size, strength, and sex drive. But we have to remember that people react differently to each other. So any treatment with testosterone should be customized for each person’s needs and monitored by a healthcare professional who knows what he’s doing. Note that the study was done more than 20 years ago. Since then there might be new findings. If you’re thinking of testosterone therapy, talk to medical experts. They can assess your situation and give you personalized advice. The study provides valuable insights into the functioning of testosterone dosing, highlighting the need for further investigation. By doing more research, we can make the most of testosterone therapy and minimize the downsides. Get a budget-friendly testosterone test without seeing a doctor.

The study above showed that 125 mg/week of injectable testosterone was enough to increase muscle. 2 ml of testosterone is 400 mg/week which will increase muscle but may cause high hematocrit, water retention, and blood pressure. How much test cypionate a week for bodybuilding? The study above showed that 125 mg/week of test cypionate is enough to increase muscle in bodybuilding without TRT side effects. References: In a study titled "Age trends in the level of serum testosterone and other hormones in middle-aged men: longitudinal results from the Massachusetts male aging study", researchers looked at how hormone levels, including testosterone, change as men get older. The article "Testosterone Replacement in Older Men: A Clinical Perspective" discusses the benefits and considerations of giving older men testosterone to improve their health. According to research found on Harvard's website, scientists have figured out what dose of testosterone works best for women. Another study called "Effects of Testosterone Treatment on Body Fat and Lean Mass in Obese Men on a Hypocaloric Diet: A Randomized Controlled Trial" explores how taking testosterone can help obese men lose fat but keep muscle while eating fewer calories.

Testosterone Injection: Subcutaneous vs. Intramuscular—Where to Inject Regardless of which TRT product you’ve been prescribed, a common question is where to inject testosterone. For decades, most men have used IM testosterone injections, primarily into the glutes, quads, or deltoids, using a 1 to 1.5-inch syringe. During the past five years, many men have also begun injecting testosterone subcutaneously (SubQ), a shallow injection into the fat layer on the abdominal or other areas—just under the skin but before reaching muscle. Many TRT patients find SubQ injections less bothersome than IM injections, as they require a smaller needle in both length and gauge. SubQ injections are also associated with less irritation for some men with IM injections. While some men may find IM injections to leave a minor soreness at the injected site, SubQ injections cause no noticeable pain or irritation. Understanding Testosterone Replacement Therapy Testosterone Replacement Therapy (TRT) is a medical treatment designed to help individuals with low testosterone levels, also known as hypogonadism. TRT aims to restore normal testosterone levels, alleviating symptoms such as low libido, fatigue, and decreased muscle mass. This form of hormone therapy can significantly improve the quality of life for those experiencing sexual dysfunction and other related issues. TRT can be administered through various methods, including intramuscular injections, subcutaneous injections, and topical gels. In this article, we will focus on testosterone injections, specifically intramuscular and subcutaneous injections, to provide a comprehensive understanding of these methods. Testosterone Injection Methods: Effects on Total Testosterone, Estradiol (E2), and PSA Testosterone Cypionate and Testosterone Enanthate are the two most commonly used forms of testosterone in men to treat hypogonadism (low testosterone). Both forms carry the same testosterone hormone; the ester is the only difference, which alters the hormone’s time release so that testosterone blood levels can remain up for a few days. These two testosterone compounds are identical in a testosterone replacement therapy (TRT) setting. Both forms are commonly used in hormone replacement therapy to treat hypogonadism in men. Where and How to Inject Testosterone? Regardless of which TRT product you’ve been prescribed, a common question is where to inject testosterone. For decades, most men have injected their testosterone intramuscularly (IM), primarily into the glutes, quads, or deltoids, using a 1- to 1.5-inch syringe. During the past five years, many men have also begun injecting testosterone subcutaneously (SubQ), a shallow injection into the fat layer on the abdominal or other areas—just under the skin but before reaching muscle. Many TRT patients find SubQ injections less bothersome than IM injections, as they require a smaller needle in both length and gauge. SubQ injections are also associated with less irritation for some men with IM injections. While some men may find IM injections to leave a minor soreness at the injected site, SubQ injections cause no noticeable pain or irritation. Many patients find it beneficial to inject weekly to maintain stable testosterone levels. Administering Testosterone Injections Safely Administering testosterone injections safely requires proper technique and precautions to ensure effectiveness and minimize risks. Before injecting, ensure the injection site is clean and free of any debris. Use a sterile needle and syringe, and follow the recommended dosage and injection frequency as prescribed by your healthcare provider. For intramuscular injections, use a longer needle (1 to 1.5 inches) and insert it at a 90-degree angle into the muscle, typically in the glutes, quads, or deltoids. For subcutaneous injections, use a shorter needle (0.5 to 1 inch) and insert it at a 45-degree angle into the fatty tissue, commonly in the abdominal area. Always dispose of used needles and syringes properly to prevent injury and contamination. By following these steps, you can administer testosterone injections safely and effectively. Choosing the Right Injection Site Choosing the right injection site is crucial for safe and effective testosterone injections. For intramuscular injections, common sites include the buttocks, thigh, and upper arm. These areas have larger muscle masses, which are ideal for proper absorption of the hormone. For subcutaneous injections, common sites include the abdomen, thigh, and buttock. When selecting an injection site, consider the following factors: Fat layer: Subcutaneous injections require a sufficient fat layer to ensure proper absorption. Muscle mass: Intramuscular injections require a larger muscle mass to ensure proper absorption. Nerve proximity: Avoid injecting near nerves to minimize the risk of nerve damage. Scarring: Rotate injection sites to minimize scarring and promote even absorption. By carefully choosing the injection site and rotating locations, you can enhance the effectiveness of your testosterone injections and reduce potential complications. What is the Best Way to Inject Testosterone? While subcutaneous testosterone injections are by far the most uncomplicated and most comfortable, the more critical question for any TRT patient is how effective this method is and how it affects the potential adverse side effects of TRT. Weekly injections are often recommended to maintain stable hormone levels and reduce side effects. A recent study from the Department of Urology at the University of California (UC) has provided us with such answers. The UC study attempted to answer four questions as they relate to IM vs. SubQ testosterone injections: Comparisons in: Total Testosterone Hematocrit (HCT) Estradiol (E2) Prostate-Specific Antigen (PSA) Two hundred thirty-two men took part in the UC study. Baseline levels were recorded for all men in the four measurement areas and then again at 6-12 weeks post-treatment. The results showed that men who underwent SubQ injections of testosterone resulted in a 14% greater increase in total testosterone levels than the testosterone level of IM patients. SubQ patients also had 41% lower hematocrit post-therapy than IM patients and 26.5% lower E2 levels. For both groups of men, there were no elevated levels of PSA. Additional Studies Comparing IM versus SubQ TRT While the UC study provides valuable data on four specific lab test values of concern and is one of the most recent studies on the topic of subcutaneous versus intramuscular testosterone injections, it is not the only information we have available. An additional Journal of Clinical Endocrinology study found that normal serum testosterone levels were maintained through SubQ injections. Most patients preferred the injection method due to less injection site pain. Similar results were found in a study headed by Dr. Al-Futais in a Canadian study that ran for one year in 2002. Similar results for subcutaneous testosterone injections have also been found in female-to-male (FTM) transgender people-based testosterone studies. The Journal of Clinical Endocrinology and Metabolism reported that FTM patients administering SubQ testosterone were found to easily reach stable and normal testosterone levels along with suitable E2 levels. The study concluded that SubQ testosterone injections are both safe and effective. These findings are particularly relevant for those undergoing gender-affirming hormone therapy, as they highlight the effectiveness and patient preference for SubQ injections. Although far less in-depth than we previously mentioned, a final study of note was published in the Journal of the Endocrine Society. Similar results to the reviews mentioned above were found, along with no significant changes between IM and SubQ patients relating to dihydrotestosterone (DHT). Interestingly, unlike the UC study, this study also measured no notable difference in E2 levels between the two categories. However, it must be noted that this particular study only included a single injection of testosterone undecanoate at 1000 mg. How to Inject Testosterone Using Subcutaneous Injections? If subcutaneous testosterone injections are right for you, you will merely need a small insulin syringe to administer the hormone. A 0.5-inch-long, 25-27 gauge needle in a 1 ml syringe will typically suffice. They also do not require aspiration, commonly used in old IM injection techniques. Unlike IM testosterone injections, SubQ injections do not require aspiration and use a smaller needle. Regardless, the aforementioned insulin needles and syringes are your best choice for comfort and ease of use. Due to the small needle size, you may find it slightly more difficult to draw the testosterone into the insulin syringe. But most men on TRT use 50-100 mg twice per week, which amounts to 0.25 to 0.5 ml of a 200 mg/ml testosterone cypionate or enanthate formulation commonly used in the United States. Those small volumes load up in just 1-2 minutes. Many TRT clinics prescribe protocols to patients to inject their testosterone subcutaneously once or twice weekly. This protocol effectively maintains stable testosterone levels with small, more frequent doses than the old dose of 200 mg once every two weeks. Two injections that split the weekly dose twice per week will suffice for most patients, such as a Monday and Thursday protocol. Is There Any Difference Between Testosterone Cypionate and Testosterone Enanthate? As mentioned early on, testosterone cypionate and testosterone enanthate are the two most commonly prescribed and lowest-cost testosterone esters worldwide. All four studies cited in our discussion were performed using Testosterone Enanthate, excluding the one using Undecanoate. However, using Testosterone Cypionate would have yielded similar, if not identical, results. Both versions of the testosterone hormone are just that, testosterone. Molecularly, there is no difference. It is merely the ester attached, and the carrier oil it may be mixed in is the only difference. Further, as the enanthate and cypionate esters have very similar time-release structures, total serum levels should be relatively the same with either compound, even if injected subcutaneously. Conclusion In conclusion, testosterone replacement therapy is a medical treatment designed to help individuals with low testosterone levels. Administering testosterone injections safely requires proper technique and precautions. Choosing the right injection site is crucial for safe and effective testosterone injections. By understanding the differences between intramuscular and subcutaneous injections, individuals can make informed decisions about their treatment options. Always consult with a healthcare professional before starting testosterone replacement therapy to ensure the best approach for your specific needs.

Your hormones control everything from energy and strength to recovery and muscle-building. Regular testing can identify imbalances that hold you back and help fine-tune your training, diet, and recovery. Here’s a quick summary of the 8 key hormone tests every athlete and bodybuilder should know about: Testosterone: Measures muscle growth and recovery potential. Cortisol: Tracks stress and recovery balance. Growth Hormone (GH): Supports muscle repair and fat metabolism. Thyroid Function: Regulates energy and metabolism. IGF-1: Reflects growth hormone activity for muscle building. Estradiol: Affects recovery, bone health, and fat distribution. DHEA: Precursor to testosterone and estrogen, key for hormonal balance. LH & FSH: Monitors reproductive health and testosterone production. Why it matters: Hormonal imbalances can lead to fatigue, poor recovery, and reduced performance. Testing provides actionable data to optimize training and avoid overtraining. Pro Tip: Start with a testosterone-to-cortisol ratio or thyroid panel if you're noticing fatigue, slow recovery, or muscle loss. Dive into the full article for details on each test and how to use them to improve your results. Fitness Improvement Requires Stress & Cortisol 1. Testosterone Levels Testing testosterone levels is crucial for athletes, as it directly affects muscle growth, recovery, and overall performance. Understanding Testosterone Testing Blood tests are used to measure two key types of testosterone: total testosterone (which includes both free and protein-bound forms) and free testosterone (the active form). For the most accurate results, it's recommended to test between 7 a.m. and 10 a.m., when levels are naturally highest [3]. Services like DiscountedLabs.com offer hormone panels at over 2,200 locations across the U.S., delivering confidential results in just 2–7 business days. This detailed measurement helps assess performance potential and identify areas for improvement. Normal Testosterone Ranges for Athletes Gender Normal Range (ng/dL) Men 300–1,000 Women 15–70 Dr. Paul Gittens, a board-certified urologist and founder of the Rockwell Centers for Sexual Medicine and Wellness, emphasizes: "It's not all about numbers. It's about how your numbers reflect with your symptoms." [2] How Testosterone Affects Athletic Performance Maintaining balanced testosterone levels is essential for any athlete aiming to maximize strength and recovery. Testosterone supports several key functions, including: Promoting muscle protein synthesis Maintaining bone density Speeding up post-workout recovery Regulating fat distribution It's worth noting that testosterone levels naturally decline by about 1.6% per year, which can influence performance over time. Signs of Low Testosterone Be alert to these potential warning signs of low testosterone: Loss of muscle mass despite consistent training Longer recovery periods after workouts Reduced strength gains Unusual fatigue during exercise Lack of motivation to train Dr. Justin Dubin, a urologist and men's health expert at Memorial Healthcare System, points out: "Just because your testosterone is very, very high doesn't mean you have a better libido or anything. Everyone's body is different." [2] 2. Cortisol Measurement Cortisol, often referred to as the "stress hormone", can directly impact recovery and performance when levels remain elevated for too long. For athletes and bodybuilders, keeping cortisol in check is key to improving training outcomes. This hormone plays a role in regulating metabolism, immune response, and inflammation [7]. Testing Methods and Timing Cortisol levels can be assessed using three primary methods: Test Type Collection Time Normal Range (8 a.m.) Blood Test Morning + 4 p.m. 5-25 mcg/dL Saliva Test Before bedtime Varies by lab 24-hour Urine Full day collection Lab-specific Impact on Athletic Performance When exercise intensity exceeds 60% of VO2 max, cortisol levels naturally rise [6]. While short-term spikes are part of the body's normal response, consistently high levels can lead to: Poor muscle recovery Weakened immune function Loss of bone density Trouble sleeping Increased fat storage Professor Chris McLellan highlights the importance of monitoring cortisol: "Cortisol testing provides coaches, trainers and health & fitness professionals with increased capacity in conjunction with existing performance monitoring methods to establish preparedness for training and competition and optimize recovery. With cortisol, what gets measured, gets managed." [4] Understanding these effects is just the first step. The next challenge is learning how to control elevated cortisol levels. Managing Cortisol Levels Overtraining can cause a surge in cortisol that slows recovery and breaks down muscle tissue [8]. To keep cortisol levels balanced: Post-workout nutrition: After exercise, drink a carb-to-protein mix in a 3:1–4:1 ratio to help regulate cortisol [5]. Training structure: Build workout routines that include proper rest periods, especially for endurance-focused athletes [5]. Recovery strategies: Incorporate stress management techniques and prioritize high-quality sleep [4]. 3. Growth Hormone Testing Growth hormone (GH) testing plays an important role for athletes and bodybuilders aiming to improve performance and recovery. Since GH levels naturally rise and fall throughout the day, accurate testing can reveal useful details about hormonal health and how well training is working. Testing Methods and Accuracy Measuring GH isn't straightforward because of its pulsatile secretion pattern. Standard blood tests aren't enough. Instead, endocrinologists rely on specialized tests: Test Type Purpose Normal Range Approximate Cost IGF-1 Blood Test Primary screening Age/gender specific $70 GH Stimulation Diagnose deficiency >4 ng/mL (adults) Varies GH Suppression Diagnose excess <1 ng/mL Varies Macimorelin Test Oral diagnostic ≤2.8 μg/L Varies Dr. Jennifer Osipoff, a Pediatric Endocrinologist at Stony Brook Children's Hospital, notes: "A random GH level is not a clinically relevant value if assessing for growth hormone deficiency or excess. Instead, endocrinologists will measure insulin-like growth factor 1 (IGF-1), a protein that is made in response to GH secretion." [10] Impact on Athletic Performance GH plays a role in muscle growth, protein synthesis, fat metabolism, and recovery. Studies show that athletes using GH supplementation gained an average of 4.6 pounds of lean body mass [11]. However, GH alone doesn't lead to noticeable improvements in strength or exercise performance. This underscores the importance of focusing on natural ways to optimize GH levels. Natural GH Optimization Tracking GH levels can help adjust training plans. Here are some insights: Women produce about 50% more GH than men over a 24-hour period [9]. GH production decreases by roughly 14% per decade after early adulthood [9]. Anaerobic workouts stimulate more GH release compared to steady-state cardio [9]. Testing Considerations When preparing for GH testing, keep the following in mind: Follow fasting guidelines carefully. Inform your doctor about any medications that could affect results. Schedule tests at times when GH levels are most likely to be measurable. Consider pairing GH testing with IGF-1 measurement for a more complete picture. 4. Thyroid Function Tests Thyroid tests provide important insights for athletes looking to refine their training. These hormones play a key role in metabolism, muscle function, and overall performance, making thyroid health essential for athletic success. Core Thyroid Panel Components Test Type Purpose Indicator TSH (Thyroid Stimulating Hormone) Initial screening test General thyroid function Free T4 Measures active thyroid hormone Direct thyroid output Free T3 Measures active thyroid hormone Reflects metabolic activity Thyroid Antibodies Identifies autoimmune issues Autoimmune conditions How Thyroid Hormones Affect Performance Thyroid hormones impact several areas critical to athletes: Muscle strength, recovery, and protein synthesis Energy production and usage Heart rate and blood pressure regulation Body temperature control Weight stability Dr. Sumedha Chablani, an endocrinologist and clinical assistant professor at NYU Grossman School of Medicine, notes: "Both hypothyroidism and hyperthyroidism can present with fatigue or changes in energy levels, which can impact athletic performance and endurance."[13] Understanding these effects helps athletes address potential issues early. Signs to Watch For Athletes should pay attention to these symptoms for thyroid imbalances: Hyperthyroidism (Overactive Thyroid) Unexplained weight loss with increased appetite Muscle weakness Rapid heart rate Excessive sweating Sleep problems Hypothyroidism (Underactive Thyroid) Persistent fatigue Trouble building or maintaining muscle Slower recovery from workouts Joint and muscle pain Unexplained weight gain If you notice these signs, testing is critical to confirm and address the issue. Testing Tips for Athletes Studies show that 57–90% of hypothyroid patients have elevated creatine kinase (CK) levels [12]. To ensure accurate results: Schedule tests in the early morning. Keep follow-up tests at consistent times. Let your provider know about any medications, supplements, or thyroid concerns. Athletes using androgenic anabolic steroids should be particularly cautious, as these substances can disrupt thyroid function [12]. Supporting Thyroid Health Regular testing can guide adjustments to training and recovery routines. Thyroid hormones are important for muscle function, especially in promoting faster muscle fiber types in muscles with a higher proportion of slow fibers [14]. To maintain thyroid health, athletes should focus on: Prioritizing quality sleep Managing training-related stress Following a well-rounded diet Monitoring thyroid levels regularly Taking care of thyroid health ensures you’re getting the most out of your training efforts. sbb-itb-2f7d8a0 5. IGF-1 Blood Test The IGF-1 blood test measures muscle growth, recovery, and tissue development influenced by growth hormone activity. IGF-1 works alongside growth hormone to support tissue building and muscle protein synthesis. Understanding IGF-1's Role About 75% of IGF-1 is produced in the liver [18]. Unlike growth hormone, which fluctuates throughout the day, IGF-1 levels remain steady, making it a reliable marker for assessing average growth hormone activity [16][17]. IGF-1 Function Impact on Performance Muscle Growth Promotes protein synthesis and muscle development Recovery Activates satellite cells to aid muscle repair Metabolism Improves insulin sensitivity and glucose uptake Bone Health Contributes to bone growth and strength Testing Considerations The United States Anti-Doping Agency (USADA) highlights the importance of medical oversight when it comes to IGF-1: "IGF-1 is produced in response to physiological or pharmaceutical growth hormone (GH), and is responsible for many of the anabolic effects of GH. It can enhance the production of lean muscle as well as aid in recovery time, but when used without medical necessity, exogenous IGF-1 can cause serious harm." [15] Supporting IGF-1 Naturally Boost IGF-1 levels through a diet rich in protein and selenium, paired with progressive strength training. Age-Related Trends IGF-1 levels naturally rise during childhood, peak during puberty, and decline with age. Always refer to age-specific ranges for accurate interpretation. Performance Benefits IGF-1 can improve athletic performance in several ways: Stimulating satellite cells to repair and rebuild muscle fibers Activating the mTOR pathway to increase protein synthesis Reducing protein breakdown by inhibiting FoxO-1 Enhancing insulin sensitivity for better glucose uptake [18] Regular IGF-1 testing can help fine-tune your training plan while ensuring compliance with anti-doping regulations. 6. Estradiol Measurement Estradiol testing is valuable for both male and female athletes aiming to improve their performance. This hormone plays a role in muscle growth, recovery, bone strength, and overall hormone balance, making it an important factor in crafting an effective performance strategy. Normal Reference Ranges Understanding baseline estradiol levels is essential for accurate analysis: Gender/Status Normal Range (pg/mL) Male 10–50 Female (Premenopausal) 30–400 Female (Postmenopausal) 0–30 Impact on Athletic Performance Balanced estradiol levels contribute to muscle strength, recovery, bone density, fat distribution, and mood stability. Studies indicate that estradiol can enhance muscle recovery and strength [20]. Testing Considerations Accurate estradiol measurements require sensitive testing methods. Opt for FDA-approved techniques to ensure reliable results. Warning Signs In men, estradiol levels above 40 pg/mL may indicate potential performance issues. Low estradiol levels can result in: Reduced bone density Slower muscle recovery Sexual health challenges Increased fat accumulation [19] Identifying these imbalances early helps fine-tune training and overall health strategies. Optimization Strategies To maintain healthy estradiol levels: Engage in strength training and maintain a balanced body composition Follow an anti-inflammatory diet rich in vitamin D and calcium Manage stress effectively and prioritize good sleep For athletes using performance-enhancing substances, avoid excessive estradiol suppression, as it can cause negative health effects [19]. Making informed adjustments based on estradiol levels can lead to better training outcomes. Regular Monitoring Incorporate estradiol testing into your routine hormone panel checks to refine your performance strategy and identify any additional markers for optimization. 7. DHEA Blood Test The DHEA blood test is a useful tool for monitoring hormonal health. DHEA, a steroid hormone produced mainly by the adrenal glands, plays a key role in the production of testosterone and estrogen. Understanding DHEA Levels DHEA-S (sulfate) levels naturally vary based on age and gender. They typically peak during puberty and slowly decline as you age. Since lab reference ranges can differ, it's important to review your results with a healthcare provider. How DHEA Affects Performance DHEA can influence athletic performance in several ways: It supports muscle growth when combined with resistance training. It helps reduce muscle damage and soreness with doses of about 100 mg daily. It aids in maintaining hormonal balance as a precursor to testosterone and estrogen [22] [23]. When Should You Test? Athletes might consider testing if they notice signs like unexplained fatigue, reduced performance, difficulty building or maintaining muscle, slow recovery, or other hormonal imbalance symptoms. Women experiencing menstrual irregularities or signs of virilization might also benefit from testing. Identifying these issues early can help you address potential setbacks. What High or Low Levels Mean High DHEA-S levels: Could indicate conditions like congenital adrenal hyperplasia, adrenal tumors, or polycystic ovary syndrome (PCOS). Low DHEA-S levels: May suggest adrenal insufficiency or hypopituitarism. They might also reflect the natural decline in hormone production with age. Tips for Maintaining Healthy DHEA Levels Athletes looking to maintain or improve their DHEA levels can take these steps: Use trusted providers like Discounted Labs for hormone panels at over 2,200 U.S. locations. Get regular tests every three to six months to track changes. Prioritize quality sleep, manage stress, and follow a balanced diet to support overall hormonal health. Key Points to Remember DHEA supplements are banned by the World Anti-Doping Agency (WADA) [21]. Research shows that plasma DHEA-S levels can drop by up to 80% between ages 25 and 75 [22]. Regular blood tests and professional guidance are essential for keeping your hormones in check and staying on top of your performance. 8. LH and FSH Testing LH (Luteinizing Hormone) and FSH (Follicle-Stimulating Hormone) tests offer insight into hormonal balance and endocrine health, especially for athletes and bodybuilders. These hormones, produced by the pituitary gland, play key roles in reproductive health. What Do LH and FSH Do? In men, LH stimulates the Leydig cells in the testes to produce testosterone, which is crucial for sperm production. FSH, on the other hand, supports the development of healthy sperm. For women, LH is involved in triggering ovulation and regulating the menstrual cycle, while FSH helps ovarian follicles grow and mature. Normal LH levels in men aged 20 to 70 usually range from 0.7 to 7.9 IU/L [25]. These functions highlight why testing is important, particularly when performance or recovery issues arise. When Should You Get Tested? Consider testing LH and FSH levels if you notice: Unexplained fatigue or a drop in performance Loss of muscle mass or strength Low sex drive Irregular menstrual cycles (for female athletes) Struggles with workout recovery What Do Test Results Mean? Elevated levels may indicate ovarian or testicular failure, while low levels could point to problems with the pituitary gland or hypothalamus. These imbalances can result from chronic stress, overtraining, poor recovery, or nutritional gaps [26]. Supporting Healthy Hormone Levels To maintain balanced LH and FSH levels, athletes can: Eat a well-rounded diet Adjust training intensity as needed Prioritize recovery time Address insulin resistance through dietary changes [24] Consider a Mediterranean-style diet to support overall hormonal health The Importance of Regular Monitoring Routine testing helps athletes keep track of their hormone levels and address imbalances early. Consulting healthcare professionals ensures proper interpretation of results and helps guide effective interventions. This is particularly important for competitive athletes, as prolonged training stress can disrupt the hypothalamus and reduce LH production [24]. Conclusion Regular hormone testing plays a crucial role for athletes who want to fine-tune their performance. Research shows that up to 85% of people may deal with hormonal imbalances [27], making these tests an important tool for staying in top physical shape. For instance, a testosterone-to-cortisol ratio drop of 30% or more can signal poor recovery and overtraining [28]. Experts like Dr. Zane Hauck and Dr. Mini Sara Cherian highlight how blood tests help athletes adjust workload, recovery, and overall health [1][29]. These insights ensure training programs are based on solid data. To get the most out of hormone testing, athletes should keep these factors in mind: Timing Matters: Tests should account for variables like time of day, hydration, training intensity, and - for women - the menstrual cycle [30]. Diet Adjustments: Results may suggest dietary changes. For example, consuming up to 2 grams of protein per kilogram of body weight and maintaining moderate fat intake can help keep hormone levels in check [30]. Recovery Insights: Monitoring hormones can guide recovery strategies and help avoid overtraining [30]. From testosterone to LH/FSH, each test adds to a comprehensive view of hormonal health. Fortunately, FDA-approved labs across the country now widely offer these tests, making it easier than ever for athletes to maintain optimal hormonal health.

The Cystatin C Blood Test The cystatin C blood test is used to monitor kidney function in people experiencing or suspected to have, kidney disease (1). If a physician suspects that you’re suffering from impaired kidney function they will likely order a cystatin C blood test. The cystatin C test can be done instead of the creatinine or creatinine clearance test in cases where those tests aren’t appropriate (2), such as: In patients with cirrhosis Cases of morbid obesity Malnourishment Reduced or more than "normal" amount of muscle mass Patients taking creatine supplements that are increasing their creatinine and decreasing their estimated creatinine clearance (eGFR) Since the concentration of cystatin C in the blood will not change due to infection or inflammation and isn’t affected by body weight, lean mass, drugs or diet - cystatin C level could be a more reliable indicator of kidney health than creatinine (2). On the other hand, creatinine has been shown to be affected by higher body weight and lean mass. Testing for cystatin may also be useful to detect kidney disease early when the affected person isn’t experiencing many (if any) symptoms, and other test results are normal. What is Cystatin C? Cystatin C is a protein found in almost all the cells in the body. Cystatin C helps to regulate the activity of enzymes needed to break down bigger molecules both inside of and around those cells (3). Cystatin C level in the blood can be measured to determine how well the kidneys are functioning (3). The kidneys, liver, and spleen all work to filter the blood and excrete any waste substances as urine. This filtration process happens in a microscopic structure in the kidneys; the glomerulus (4). Each kidney contains approximately one-million glomeruli that function as tiny sieves to extract waste. The glomerular filtration rate (GFR) rate is a measure of how well the glomeruli are filtering blood (4). If the kidneys and glomeruli are impaired, the GFR could decrease. A decreased GFR can cause certain proteins to accumulate (like cystatin C and creatinine) in the blood. So, the Cystatin C blood test is used to measure circulating levels of cystatin C. The levels of cystatin C in the blood can be used to assess the glomerular filtration rate to indirectly provide an assessment of kidney function. Risk factors for Kidney Disease Over 30 million American adults have kidney disease, but most of them aren’t aware of it (5). This lack of awareness is because people who have kidney disease tend to not experience any symptoms until kidney disease is in its latest stages. This happens when the kidneys are failing or when there are already large amounts of protein present in the urine. If your risk for kidney problems is already high due to hypertension (high blood pressure, diabetes, kidney failure runs in your family or you’re over 60 years of age (6), it’s crucial that you get tested yearly for kidney disease. Symptoms that May Mean a Cystatin C Test is Needed Although the only way to find out if you have kidney disease is to get tested, some symptoms indicate you may be experiencing kidney problems. These are five symptoms that could indicate impaired kidney function (7): 1) You need to urinate more frequently than normal. If you need to urinate more frequently, particularly at night, it can be a sign of kidney disease. When the kidney’s filters aren’t functioning well, it can result in an increased need to urinate. 2) Swollen ankles and feet. A decrease in kidney function may cause sodium retention which can make feet and ankles swell. Lower extremity swelling can also indicate heart or liver disease and circulatory problems. 3) Foamy urine. The presence of bubbles in your urine, especially persistent ones that require several flushes before they go away, could indicate excess protein is present in the urine. This foam may resemble the foam seen when scrambling eggs, since a protein found in urine is the same protein found in eggs: Albumin. 4) Dry and itchy skin. Healthy kidneys perform many critical functions. From removing waste and excess fluid from the body and helping to make blood cells to helping keep bones healthy by maintaining the correct amount of minerals in the blood. When skin becomes dry and itchy, it can be a symptom of mineral or bone disease that can accompany late-stage kidney disease because the kidneys can no longer maintain the correct balance of minerals in your blood. 5) Fatigue. A severe impairment of kidney function may lead to an excess of toxins and impurities in your blood. This accumulation of toxins can result in fatigue and can make it difficult to concentrate. Tiredness and weakness may also be the result of anemia, which is another complication of kidney disease. What Else Can Cause High Cystatin C Levels? While abnormally high cystatin C levels may indicate that you have a potentially serious kidney condition, it’s not the only medical issue that can cause this. Elevated levels of cystatin C could also be caused by conditions like (8,9,10) : Diabetes Cancer HIV Hyperthyroidism Hypothyroidism It’s best to speak to your doctor to understand precisely what the results of a cystatin C test mean for your health.   BUY THE CYSTATIN-C TEST HERE   References Mayo Clinic.

 Exercise has long been praised for its role in hormonal regulation, especially when it comes to improving testosterone levels. While that is undoubtedly a significant benefit, the realm of exercise extends much farther than hormones alone. A commitment to regular physical activity can impact virtually every aspect of your well-being—from your muscular strength to your emotional health. At DiscountedLabs.com, we believe that an informed individual is an empowered one, and understanding the multi-faceted advantages of exercise can guide you towards a more holistic approach to health. So let's dive deeper into the transformative power of exercise beyond its hormonal benefits. We will delve into how exercise can transform you into a more positive version of yourself, both physically and mentally. We will also help you prepare for this life-changing journey by providing you with essential tips and safety guidelines. Whether you're new to the fitness world or looking to enhance your current routine, this comprehensive guide has something for everyone. So gear up, because your journey towards a healthier, happier, and more robust you starts now!  The Benefits of Exercise  Why Exercise Matters Beyond Hormones What's more important to know is that exercise does a lot more than affect your testosterone levels. It helps you in many ways:  Strengthening Muscles Makes your muscles work better. Burning Belly Fat Gets rid of fat in your stomach area. Building Muscle Mass Makes your muscles bigger. Lowering Bad Cholesterol Reduces bad cholesterol in your blood. Reducing Triglycerides This can happen especially if you have high levels of triglycerides to begin with. Improving Mood Helps you feel happier and less stressed. Strengthening Bones Good for both men and women. Improving Lung Function Makes your lungs work better. Getting Started with Exercise Preparing for Your Fitness Journey Here's what you need to think about before you start working out: Before You Start Check your blood pressure, heart rate, weight, body size, cholesterol, triglycerides, and blood sugar with your doctor to make sure you're ready to exercise without any health problems (3). If You Are Tired If you feel weak, start with walking. Walking can help you feel better and get ready for harder workouts. A simple step counter can help you track your progress. Cardiovascular/Aerobics Exercise Exercises like walking, biking, or using a treadmill can help your heart and lungs. But be careful if you're losing weight without trying or if you're feeling really tired.  Weight Training (Resistance Exercise) Lifting weights can help build your muscles. But remember not to overdo it. Too much exercise can actually be bad for you. Other Important Tips From learning the right way to exercise to finding the right weight and taking safety precautions, here's a comprehensive guide. Safety First! Always prioritize safety to prevent injuries. Do not exercise a body part if it is hurting. Commit Yourself Joining a gym or finding a workout buddy can help you stick with it. Do Not Overtrain! Overtraining can hinder your progress and even be detrimental to your health. Recommended – A Workout Log Keeping track of your workouts can help you avoid overtraining and monitor your progress. Food and Hydration 1- Drink at least 8 glasses of water a day to keep hydrated. Dehydration can rob you on energy for your workouts. Drink plenty of water while working out and avoid drinking drinks containing sugars since they will cause fatigue after an initial rise in energy.2- Do not work out after eating a regular meal. Wait at least two hours. If you need a snack, have some fruit and a slice of toast with peanut butter 1 hour or more before working out. Do not consume protein shakes before working out (leave it for after the work out). Digestion will slow down your workouts and bring your energy down.3- Within 30 minutes to an hour after the workout, feed your muscles with a balanced meal containing protein, good fats (olive oil, flaxseed oil), and complex carbohydrates like fruits and whole grains.4- Supplements like glutamine, creatine, and whey protein may be a good thing to consider. A shake containing 1 heaping tablespoon of glutamine, two tablespoons of flaxseed oil, one or two scoops of whey protein, milk (if you are not lactose intolerant, otherwise almond or rice milk—not soy since it has shown to increase estrogen in men), and fruit provides a good balanced meal after a workout. For Beginners: Once-A-Week Training “Warm-up set” (wu) weight means a set where you use a weight that is about 50-60% of the heavyweight set that you use. “Heavy” (hvy) means a weight that you are only capable of lifting 6-12 times before complete muscular failure.1. Barbell flat bench press – 2 wu and 1 hvy set2. Curl-grip pulldowns – 2 wu and 1 hvy set3. Squat or seated leg press – 2 wu and 1 hvy set. Squats are a “best” exercise, but some people have to substitute the leg press because their back won’t tolerate squats.Warm-up sets employ poundage that you know you can easilyhandle for 12 repetitions (reps). Rest for about one minute between sets or longer – until you feel like you have enough energy to go again. Two warm-up sets should be enough to warm all the joints involved without tiring you too much. Then do the heavy set. You want to lift the weight until you can’t lift it again. This is called “momentary muscular failure”.Important: It’s important to go to failure to trigger the muscles to grow, but challenge yourself to the best of your ability. Your level of intensity, in the beginning, won’t be as much as it can be later after you’ve been at it for a while.Do this workout on a day when you feel relatively good.If you find that you feel exhausted during the beginning efforts, pace yourself more carefully and make sure your nutrition is good. You should be getting balanced nutrition (like food!) three to six times a day and be sure to get plenty of rest and recovery. Protein drinks can fill in between meals. (I.e. three meals with two or three drinks.) Continue with once-a-week workouts until you find that you feel good enough to work out on a second non-consecutive day of the week. Then do this same workout twice a week. When you feel good enough to work out three days a week, it’s time to start splitting the workout up to separate the body parts. You will also be starting to train your heavy sets with more intensity — so you’ll see an acceleration of the muscular gains. THE THREE DAY SPLIT Day #1 Chest, Shoulders, TricepsBarbell flat bench press - 2 wu and 1 hvy setBarbell military press - 2 wu and 1 hvy setTriceps pushdowns - 2 wu and 1 hvy setDay 2: Back, Biceps, AbsCurl grip pulldowns – 2 wu & 1 hvy setBarbell biceps curl - 2 wu & 1 hvy setCrunches – 3 sets of 10-20Day 3: Quadriceps, Hamstrings, and Calves (Legs)Squat or leg press - 2 wu and 1 hvy setAgain, the squat is a better overall exercise, but some people cannot do it because of back problems, so they do the leg press.Lying leg curls - 2 wu and 2 heavy setsStanding calf raises – 2 wu & 1 heavy setWorkout LogKeep a record of your workouts and when you can lift a weight for 12 reps, raise the weight 5-10 lbs. so that you can only lift 6 reps. Then try to increase the number of reps you can lift each time you workout to arrive at 12 reps again, and repeat the progression so that you keep increasing the weight you lift. As you grow stronger, you will grow bigger muscles. You’ll probably be pretty sore during your recovery days. Let yourself heal so that the soreness goes away for best recovery and growth, even if this means you put several days between workouts.Keep in mind that the goal is to gain strength and lean body mass. Usually, strength precedes size, so you get stronger and then notice that you’re getting more muscular.Descriptions of the Exercises:One of the best web sites that show video clips of exercises and explain anatomy isExercise videos: Click on the body part you want to exerciseExRx.net : Exercise Directory Effect of Exercise of Lab Test Values Please read about the effect of exercise or supplements like creatine on liver enzymes and creatinine (kidney function).

The Top Boner Killers What Causes an Erection? The Role of Blood Flow An erection begins when the penile smooth muscle relaxes, enabling blood to fill the corpus cavernosum, two cylindrical “caverns” of spongy tissue running within the penis. Stage two of the erection process occurs with this infilling of the corpus cavernosum. The inflow of blood expands the spongy tissue, which begins to pinch off the emissary veins of the penis, decreasing outflow, and—voila!—the erection begins to build. Continue reading this article to find out what the top erection killers are and how to avoid them. For more details on how erections work, continue reading this article.   Why Can't I Maintain an Erection? Top Erection Killers It is estimated that some degree of erectile dysfunction (ED) affects half of all men over the age of 40 and that 150 million men worldwide suffer from ED. There are many reasons a man might not be able to maintain a healthy erection, many of which play into our daily habits and lifestyle choices. If you are having trouble getting or maintaining an erection, consider testing for ED, as an imbalance of hormones could be the root of the problem. Many things that have the potential to hurt our general and sexual health are culturally acceptable so they simply never cross our minds. Low Testosterone: Testosterone plays a critical role in our sexual health and can be directly linked to libido. Not only do lower levels of testosterone equal lower sex drive, but also it can lead to venous leakage. This condition is characterized by the inability to “pinch off” emissary veins that carry blood away from the penis. This results in blood leaking out of the corpus cavernosum as quickly as it can be filled, making a lasting erection impossible to maintain. If you are having erectile difficulties, a simple testosterone test is a great first step on the road to treatment. Loss of Morning Erections: Morning erections, or the lack thereof, can be a good way to begin troubleshooting if you have psychological erectile dysfunction. The idea is that if you can achieve an erection by any means, nighttime or otherwise, then your issue is probably more mental than physical. Morning erections oxygenate erectile tissue and fight off penile fibrosis, keeping the penis elastic and healthy. High Blood Pressure: High blood pressure often results in hardening arteries, constricting blood vessels, and damage to the thin membrane that lines our hearts and veins. This restricts the amount of blood your body can readily provide to your penis when it is “go time.” Not only can high blood pressure kill an erection, but it can lead to a host of other, much more immediate, medical complications, including heart attack and stroke. Any Cardiovascular Risk Factor: Almost anything hard on the heart and cardiovascular system is going to lead to erectile dysfunction. The reason is simple: erectile dysfunction is strongly related to endothelial dysfunction, where the delicate lining of your arteries becomes damaged and does not output nitric oxide as it should. This is the primary reason that lifestyle is so critical: exercise, weight management, and diet all powerfully affect how your body carries blood and oxygen to your organs. Cholesterol Management: High cholesterol has been linked to erectile dysfunction due to its direct correlation with elevated LDL or “bad cholesterol.” LDL carries cholesterol to the arteries, which, when oxidized, damages artery walls. Contrary to HDL, which aids the body in eliminating excess cholesterol, elevated levels of LDL can significantly impact your heart, cardiovascular system, and ultimately, your erectile health. Bike Seats: Many standard bike seats can damage the pudendal nerve that is connected to the penis. If you have done a lot of bike riding recently and have erectile dysfunction, this is something to consider. The solution can be as simple as changing out your bike seat. Bisphenol-A and Phthalates: Our modern environment is filled with toxins that have been proven to damage the reproductive and sexual functions of animals, and as primates, men are no exception. Bisphenol A and phthalates are chemical compounds used in the production of polycarbonate plastics that litter our world today. These chemicals are filled with endocrine disruptors and xenoestrogens that, over time, can severely impact one’s hormonal and sexual health. Prolactin: Prolactin is a hormone that stimulates breast development and milk production in women; it serves no known normal function in men. However, high prolactin can decrease testosterone, lower libido, and cause sexual dysfunction. This is because high prolactin suppresses the secretion of gonadotropin-releasing hormone, which stimulates the production of testosterone in men and estrogen in women. Estradiol (E2): Estradiol is the primary form of estrogen during our reproductive years. In men receiving testosterone replacement therapy (TRT), the body can sense increasing levels of testosterone and aromatizes 0.4% of it to estradiol to compensate. Very high and low E2 in relation to testosterone levels can sabotage TRT results, leading to diminished libido. Testing for ED will give you a good idea of what hormones you have an excess or lack of. Excess Weight: Being overweight can lead to a plethora of health complications, including heart disease, high blood pressure, diabetes, and many more. Excess weight has also been proven to lower testosterone, increase estrogen, raise inflammation, and boost insulin levels. Together, these factors can significantly impact your sexual life. Smoking: Not just cigarette smoke, but any sort of burning inhalant is bound to damage your lungs and cardiovascular system. Smoke can also cause arteries to constrict and narrow, allowing less blood flow to the penis. Medications: Many, many medications will kill erections. Some lower testosterone. Some raise prolactin. Some have a sedating effect by raising serotonin levels. Some alter dopamine functions. The bottom line is that if you are on medication and having erectile difficulties, this is one of the first places that you should look. Depression: Depression is an acutely debilitating condition, not just mentally, but physically as well. Depression causes stress to the body, which, in turn, lowers testosterone. Depression also correlates with heart disease, as depressed individuals are less likely to be consistently physically active. Depression also elevates cortisol levels, which destroy neurons in the brain. All of these factors can lead to erectile dysfunction, which can often worsen depression. This bidirectional relationship reinforces the need to take care of one’s mind as well as body. Recreational Drugs: Many men do not realize that even something as relatively benign as marijuana use can affect their sex life. However, it has been proven to lower testosterone and damage the body’s cardiovascular system. Harder drugs, such as cocaine, heroin, ecstasy, or prescription painkillers, can have even more detrimental effects. They greatly increase one’s risk of developing heart disease, cause plaque buildup on artery walls, and severely reduce ejaculatory volume. In short, drugs age the body faster than normal, and that includes the penis. Consider carefully before indulging in your favorite recreational substances, as they can destroy gonad function, lower testosterone levels, and potentially lead to heart failure. Lack of Sleep: Not getting enough sleep at night can significantly lower testosterone levels, leading to erectile dysfunction. Ensure you get quality sleep to maintain sexual health. Watching TV in Bed: Spending too much time watching TV in bed can lead to a sedentary lifestyle, which negatively affects erectile function. Regular physical activity is crucial for maintaining sexual health. Watching Comedy Series: Engaging in light-hearted activities like watching a comedy series can reduce stress and improve overall well-being, which is beneficial for sexual health. Does More Testosterone Equal a Better Sex Life? As we’ve discussed, testosterone plays a critical role in stimulating sex drive and developing and maintaining erections. Low levels of testosterone have been directly linked to health conditions and dulled libido. However, this is not indicative of a simple “more is more” relationship between T and sexual health. Testosterone is a hormone that must be balanced properly, as an influx of it signals your body to increase the production of estradiol and prolactin. Watching too much TV, especially in bed, can lead to a sedentary lifestyle, which negatively impacts testosterone levels and erectile function. Make sure to closely monitor your T levels with a. To achieve ideal results, it is important to keep testosterone levels between 500 and 1000 ng/dL while ensuring your levels of estradiol and prolactin do not proportionately increase. It is not uncommon for certain prescription medications to interfere with TRT as well. Many antidepressants, blood pressure medications, and cholesterol-lowering agents have been known to dampen sex drive, even with the use of testosterone replacement. Finally (and most importantly), make sure you are attracted to the person you are intimate with. Lack of attraction to our sexual partners can be the biggest hurdle in achieving a strong erection. All the testosterone and lifestyle changes in the world won’t result in an erection if you simply don’t want to have sex with someone. Porn addiction has also been linked to ED, as it desensitizes us to nudity and intercourse. While there are many physical contributors to ED, there are unquestionably psychological elements as well. So before testing for erectile dysfunction, make sure that you are taking care of your body and mind while properly balancing the hormones your body needs for sexual activity.

Estrogen in Men: Myths and Realities of High Estradiol In men, the liver, fat cells, and other cells aromatize testosterone to produce estradiol, which is a hormone that is more prevalent in women than in men. Estradiol is responsible for healthy bone density and cholesterol, but its role in men’s sex drive, body composition, and other variables is a source of great debate. It is crucial to understand that estrogen plays a significant role in male reproductive health, particularly in the processes of sperm production and maturation within the testes. Many men on testosterone replacement therapy (TRT) initially fear high estradiol levels since they fear it causes water retention and gynecomastia. However, it is important to note that fat cells play a significant role in the production of aromatase, which can lead to higher levels of estradiol in the body. Below, we will discuss why most men on TRT do not have to be overly concerned about the estradiol lab ranges that are ill-fitted for men on TRT, as the ranges of LabCorp and Quest were not derived from a dataset of men on TRT who usually have higher total testosterone blood levels. What is Estradiol and Why is it Important for Men's Health? Estradiol is a type of estrogen hormone that plays a crucial role in men’s health. Often referred to as a 'female sex hormone,' estradiol also plays a crucial role in male health. It helps regulate bone density, cognitive function, libido, and mood. However, high levels of estradiol in men can lead to negative effects like decreased muscle mass, increased body fat, and hormonal imbalances. Men’s liver, fat, and other cells aromatize testosterone to produce estradiol, a hormone that is more prevalent in women than in men. Estradiol is responsible for healthy bone density and cholesterol, but its role in men’s sex drive, body composition, and other variables is a source of great debate. Many men on testosterone replacement therapy (TRT) initially fear high levels of estradiol since they fear it causes water retention and gynecomastia. We will talk about why most men on TRT do not need to worry too much about the estradiol lab ranges that do not work well for them because LabCorp and Quest did not get their ranges from a group of men on TRT who usually have higher total testosterone blood levels. High levels of estradiol in men are associated with abdominal obesity and an increased risk of cardiovascular disease. What is High Estradiol?: Predicted Blood Levels in Young and Older Men on TRT Transcript of video below: There needs to be more clarity on the subject since LabCorp and Quest have very narrow, sensitive estradiol test ranges. Those estradiol test ranges were primarily derived from men not on testosterone replacement therapy. Men on TRT tend to have higher testosterone levels than men not on testosterone replacement. So, believe it or not, a paper published many years ago predicts estradiol and DHT levels in men given different doses of testosterone. This study examined what happens to blood levels of testosterone, estradiol, and DHT when injecting different testosterone doses in young and older men. This study was very nicely done at the Boston University School of Medicine by well-known testosterone researchers. Dr. Basin is one of them and has done excellent work for the last 30 years. Video: How to Predict High Estradiol in Men Testosterone is the precursor hormone for estradiol. The aromatization of testosterone in the liver, fat, and other cells, including the testes, results in estradiol, a hormone that is more prevalent in women than men. Nature created it for a reason. It is responsible for healthy bone density and cholesterol, but its role in men's sex drive, body composition, and other variables is a source of great debate. Many anti-aging or men's health clinics prescribe aromatase inhibitors (AIs) to men who start testosterone replacement therapy (TRT). Higher estradiol blood levels in the presence of low testosterone can cause breast tissue growth (gynecomastia) in some men and possibly other issues. Some people speculate that high estradiol levels can also lead to difficulty achieving or maintaining an erection, but no scientific papers have been published on this subject. Since higher testosterone blood levels can result in higher estradiol levels in men, the belief is that using an AI will prevent breast tissue growth and erectile dysfunction by lowering any potential increase in estradiol. However, we have no data on how high is too high when it comes to this hormone in men using testosterone therapy. Emerging data show that low testosterone-to-estradiol ratios may correlate more closely to infertility, gynecomastia, and erectile problems than high estradiol levels alone. The truth about these speculations is starting to emerge, but we still need more data to say what the upper value of the optimal range of estradiol in men is. We have a lot of evidence about the lower side of the optimal range since it has been found that estradiol blood levels below 10–20 pg/mL can increase bone loss in men. A recently published study also nicely demonstrated that low estradiol could be associated with higher fat mass and lower sexual function in men. So, be careful when a clinic wants to put you on an aromatase inhibitor without first justifying its use. Increased Aromatase Activity and the Role of Aromatase Inhibitors in Men Aromatase is an enzyme that converts testosterone to estradiol, a form of estrogen. Germ cells, along with Leydig cells, are significant sources of estrogen production in the testes. In men, aromatase activity is typically low, but certain conditions can increase it, a process known as aromatase overexpression. This can lead to higher levels of estradiol in the body, which can have negative effects like decreased libido and muscle mass in the adult male. However, some studies suggest that moderate increases in estradiol may have cardiovascular benefits. One condition that can increase aromatase activity and therefore estradiol levels is aromatase excess syndrome, a genetic condition that affects both males and females. It’s important for men to maintain healthy levels of both testosterone and estradiol, and understanding the role of the aromatase enzyme, especially in conditions like aromatase excess syndrome, is crucial in managing estradiol levels. Estradiol in Men After Different Testosterone Doses: Study Details This study's findings were published in the Journal of Clinical Endocrinology and Metabolism in 2010. The fantastic thing is that nobody has reviewed it, even though it's probably the most important paper on what happens to estradiol and DHT in men on TRT. The study enrolled 51 young men aged 19 to 35 and 52 older men aged 59 to 75. These men were given a gonadotropin-releasing hormone agonist to shut down their gonadotropins, LH and FSH, testosterone, estradiol, and DHT. So, these were courageous volunteers who were willing to have their hormones wholly shut down. So, why did they do this? They did it because the researcher wanted to start from zero regarding hormones. So, those men were given injections of different doses of testosterone enanthate, 25, 50, 125, 300, and up to 600 milligrams a week for five months. And the researchers measured the testosterone, estradiol, and DHT blood levels. Unfortunately, they used the old estradiol test based on immunoassay. This estradiol test may not be the best for accurate estradiol testing. The use of an ultra-sensitive estradiol test is more accurate since it has no interference from CRP or inflammatory markers Usually, the sensitive estradiol is 20% lower than the estradiol levels measured by the old test. Let's assume that most of these men did not have inflammation. Here are their baseline characteristics. Interestingly, they were even exposed to such high doses of testosterone. So, after a four-week controlled period, they were given a testosterone blocker, the gonadotropin-releasing hormone agonist that shuts down gonadotropins. This drug is used to treat prostate cancer. They were randomized to receive weekly injections of testosterone enanthate for 20 weeks. The researchers found an issue with the higher testosterone dose in older men, with a few more side effects. They stopped a few men from continuing with the 600 milligrams of testosterone weekly. And then the randomization was limited to 25, 50, 125, and 300 milligrams of testosterone injections weekly. I've warned people not to use high testosterone doses, especially older people with comorbidities and heart problems. Increased blood pressure and tachycardia are some of the side effects listed in the study paper. So, what you see here are serum estradiol E2:T ratios. We talk about ratios on ExcelMale.com. Here are the opposite DHT and T ratios from what I typically talk about when dividing T by E2. And the black bars are younger men, and the white bars are older men. So, this is total estradiol, free estradiol, total DHT, and free DHT. And when we talk about free, what does that mean? It is the unbound estradiol and unbound DHT that aren't bound by sex hormone-binding globulin. And those two free estradiol and free DHT tests are rarely tested in clinics. DiscountedLabs.com does provide a free estradiol test for those who are interested. But since there are no studies about free estradiol blood levels in men, it's hard to say what a good free estradiol level is. High Estradiol in Men on TRT Most men on TRT initially fear high estradiol since they fear it causes water retention and gynecomastia. While high estradiol levels in men can cause gynecomastia, in women, similar hormonal imbalances are linked to an increased risk of breast cancer. They feel puffy; they may have more sensitive nipples. I will discuss this in another video because those symptoms are usually not connected to high estradiol per se when men have moderate to high testosterone levels. The most common cause of edema, or the problem of holding onto water weight, is a slowdown in sodium metabolism in the kidneys brought on by testosterone and androgens. Sodium (salt) retention happens in the first few weeks, especially with higher TRT doses in older men. The stimulating effects of testosterone may be to blame for the sensitive nipple issue, which typically does not cause gynecomastia. However, it is important to note that symptoms of high estrogen in men can also include swelling or enlargement of breast tissue, erectile dysfunction, infertility, depression, and delayed puberty. So, as you can tell, total E2, free E estradiol, and DHT increase with increasing testosterone doses, and this increase is much more pronounced in older men. It’s good to mention that these volunteers were not fat men. The increased fat mass has been linked to increased estradiol levels, which are often measured through body mass index (BMI). These are men with a BMI of around 26, which is not a high number. But anyway, we do see an increase. And older men, in white, tend to have a higher estradiol increase. DHT is the same thing. Although the differences were not as noted between young and old, you can tell here the free DHT. When you divide estradiol into testosterone, that’s when you see a decrease. Estradiol increases to a higher degree than testosterone, so the ratio of E2 divided by T decreases. The total DHT to T ratio is the same; it decreases as we increase the testosterone dose, but not as fast as the estradiol. It is essential to mention that 0.3% to 0.4% of testosterone is aromatized into estradiol. That’s a very tiny amount; that’s 0.4%. The conversion of testosterone to DHT by 5 alpha-reductase is around 10%. That’s why you see the scales a little more prominent on the DHT side. What to Know About Estrogen in Men Estrogen is commonly associated with women, but men also have this hormone in their bodies. The testes and adrenal glands are primarily responsible for producing estrogen in a male body. Estradiol is a type of estrogen that plays an important role in maintaining bone health, regulating cholesterol levels, and supporting brain function. Low levels of estradiol in men can contribute to a variety of health issues, such as decreased libido, erectile dysfunction, and osteoporosis. It's important for men to understand their hormonal balance, including their levels of estradiol, and work with a healthcare provider to address any imbalances or concerns related to erectile function and hormone balance. Buy an affordable, ultrasensitive estradiol test:   Understanding Androgens and Estrogens Estradiol is a type of estrogen that is found in both men and women. While it is often associated with female reproductive health, estradiol plays an important role in male health as well. Estrogens influence male reproductive function by maintaining a hormonal balance between estrogens and androgens, which is crucial for male fertility. In fact, it is responsible for regulating bone density, cholesterol levels, and even mood. When there is high estradiol in men, it can lead to a variety of health problems. Understanding the balance between androgens (male hormones) and estrogens (female hormones) is crucial for sexual development and maintaining optimal health for both men and women, especially in relation to the menstrual cycle. Risk Factors of Having High Estradiol in Men Estrogen is often associated with females, but it also plays a crucial role in men's health. High or low levels of estrogen in males can have negative impacts on their overall health. Men who have higher than normal levels of estrogen, also known as estrogen, may experience breast enlargement, erectile dysfunction, infertility, and other issues. On the other hand, men with lower than normal levels of estrogen may experience decreased bone density, muscle mass, and sex drive. It is important for men to maintain balanced estrogen levels through proper diet, exercise, and medical treatment if necessary. However, it is important to note that too much estrogen, also known as high levels of estrogen, can also be harmful to men's health, and it is important for individuals to monitor their estrogen levels and consult with a doctor if they have any concerns. How Men Can Keep Their Estrogen Levels Balanced Estrogen is typically associated with women, but men also have this hormone in their bodies. Estradiol is the most potent form of estrogen in men and plays a crucial role in maintaining bone density, sperm production, and sexual function. However, too much or too little estradiol can cause various health problems. Men can keep their estrogen levels balanced by maintaining a healthy weight, avoiding exposure to environmental toxins, managing stress levels, and getting enough sleep. A balanced diet rich in fiber and phytoestrogens, along with proper monitoring and control through hormone replacement therapy, may also help regulate estrogen levels in men, ensuring healthy sperm production. Normal Estrogen Levels in Men Estrogen is often thought of as a female hormone. However, it's also present in men, just at lower levels. One type of estrogen found in men is estradiol. Normal levels of estradiol in men vary depending on age and other factors. In general, levels range from 10 to 60 pg/mL. If levels are too high or too low, it can lead to health issues such as osteoporosis, sexual dysfunction, and mood changes. Men should discuss their estrogen levels with their healthcare provider to ensure they are within a healthy range for their age and overall health status. This includes monitoring the amount of estrogen in their body, as there are two main types of estrogen in men: estrone and estradiol, and an imbalance of these hormones can have negative effects on their health. Gynecomastia and High Estradiol in Men Gynecomastia is a condition that causes men to develop breast tissue. Studies on male mice, such as αERKO and ArKO models, highlight the effects of estrogen deficiencies on sexual behavior and fertility. One of the underlying causes of gynecomastia is an imbalance of hormones, including estradiol. Estradiol is a form of estrogen that is typically found at higher levels in women. However, men also have small amounts of estradiol in their bodies. When the balance between estradiol and testosterone is disrupted, it can lead to the development of breast tissue in men. Treatment for gynecomastia may involve addressing the hormonal imbalance through medication or surgery, depending on the severity of the condition. You can buy a gynecomastia lab test panel on Discounted Labs. Low Estradiol Can Cause Loss of Libido and Erectile Dysfunction One of the significant impacts of estradiol deficiency in men is the loss of libido. Low levels of estradiol can lead to decreased sex drive, which can cause problems in relationships and affect overall quality of life. However, it's essential to note that there are other factors that can impact libido as well, such as stress, depression, low testosterone levels, and a lack of sexual activity. If you're experiencing a loss of libido, it's important to talk to your doctor to determine the underlying cause and discuss possible treatment options. A Study Helps to Predict Normal Estradiol and DHT Test Levels in Men on TRT Most men on TRT don't have to be so concerned about the LabCorp or Quest estradiol ranges that usually scare people because they're always high. And there is statistical significance in the baseline values of young and older men. DHT increases were higher in older men. In younger men, usually, that's also connected to total testosterone and is also related to higher libido. Older men had lower DHT, which was also linked to their lower testosterone. Sex hormone-binding globulin (SHBG) is also higher in older men. The researchers in this study came up with a model with factors to predict the estradiol and DHT response curves. They provided two equations for young men (estradiol and DHT) and two for older men. Using those equations, you can roughly estimate the predicted estradiol and DHT levels for different testosterone blood levels. These equations enable us to see what is considered a “normal” estradiol level instead of using estradiol lab ranges that are ill-fitted for men on TRT. As previously mentioned, the estradiol ranges of LabCorp and Quest were not derived from a dataset of men on TRT who usually have total testosterone blood levels over 600 ng/dL (many men on TRT have T levels of 1000 ng/dL or more!). The Importance of Preserving Proper Levels of Estradiol in Men Our bodies transform 0.4% of testosterone into estradiol to balance the potentially negative effects of testosterone alone on lipids and other variables. If you have “high” testosterone, your estradiol should be “high.” Treating that estradiol with an aromatase inhibitor may not be needed and can potentially crash your estradiol level. Estradiol has essential roles in men, including the regulation of hormone levels. Estradiol comes in to protect us from higher testosterone and helps improve lipids, HDL, and endothelial function. Women tend to live longer than men because they have more estrogen to protect them against the cardiovascular risks we are all exposed to. So, don't freak out when you see the 60s, even in the 70s, depending on how high your testosterone is. And the only problem we're having in this field is that we still need to do a study that goes after symptomology depending on estradiol blood levels when we control testosterone. We know that estradiol levels under 15 picograms per milliliter cause problems with bone density and even fat gain. Many members of ExcelMale.com say that their penile sensitivity decreases when they have low estradiol. We do not know what high estradiol in men means in relation to estradiol blood levels in relation to testosterone. Can high estradiol in men on TRT with relatively high testosterone blood levels cause issues? Is there a proper and healthy testosterone-to-estradiol ratio?. If somebody is, let's say, at 1,275 ng/dL of testosterone and 64 pg/mL of estradiol, is there any consequence to that? We don't know. And the problem I'm seeing is that most of you guys are assuming too much; you're assuming that because you're holding water or you have sensitive nipples, you have high estradiol. And you start treating with an AI without even testing your blood levels of estradiol, especially using the sensitive assay. That concerns me because once you start treating with an AI, you can crash your estradiol. “Crashed estradiol” has become one of the most significant traffic source keywords for ExcelMale because people are experiencing that more and more. I hope you enjoyed the presentation.

Thanks a lot, and stay safe. Estrogen Dominance and Hormonal Imbalance Estrogen dominance occurs when there is an imbalance between estrogen and testosterone levels in the body. This hormonal imbalance can lead to a range of symptoms, including weight gain, mood swings, and decreased libido. Men experiencing estrogen dominance may notice an increase in body fat, particularly around the abdomen, and may struggle with emotional changes such as irritability or depression. Additionally, estrogen dominance can negatively impact overall health by contributing to conditions like insulin resistance and cardiovascular issues. Maintaining a proper balance between estrogen and testosterone is crucial for optimal health and well-being. Exposure to Endocrine Disruptors and Environmental Toxins Endocrine disruptors and environmental toxins can significantly impact estrogen levels and overall health. These substances, found in everyday items like plastics, pesticides, and personal care products, can mimic the effects of estrogen in the body, leading to hormonal imbalances. When these toxins enter the body, they can bind to estrogen receptors, disrupting the natural hormonal balance and potentially causing a range of health problems. It’s essential to be aware of these environmental toxins and take steps to minimize exposure, such as choosing organic foods, using natural personal care products, and avoiding plastic containers. Other Non-Reproductive Effects of High Estrogen High estrogen levels can have a range of non-reproductive effects on the body, impacting various aspects of health and well-being. Some of the common non-reproductive effects include: Weight gain and obesity: Elevated estrogen levels can lead to increased body fat, particularly around the abdomen, contributing to obesity. Mood swings and emotional changes: High estrogen can cause mood swings, irritability, and even depression. Fatigue and low energy: Men with high estrogen levels may experience chronic fatigue and a general lack of energy. Insomnia and sleep disturbances: Hormonal imbalances can disrupt sleep patterns, leading to insomnia and poor sleep quality. Skin problems: High estrogen levels can cause skin issues such as acne and rosacea, affecting overall skin health. Maintaining balanced estrogen levels is essential for overall health and well-being, and addressing any hormonal imbalances can help alleviate these symptoms. Foods that Lower Estrogen: Cruciferous Vegetables and Sulforaphane Cruciferous vegetables, such as broccoli, cauliflower, and Brussels sprouts, are known for their ability to help lower estrogen levels in the body. These vegetables contain a compound called sulforaphane, which has been shown to support the detoxification of excess estrogen. Incorporating cruciferous vegetables into your diet can help maintain healthy estrogen levels and support overall hormonal balance. Additionally, these vegetables are rich in fiber and other essential nutrients, making them a valuable addition to a healthy diet. By including more cruciferous vegetables in your meals, you can naturally help regulate estrogen levels and promote better health.

TRT Blood Work Tests For Monitoring Men on Testosterone Therapy Before undergoing testosterone replacement therapy (TRT), it’s vital to obtain a number of blood tests, which require a blood sample. The main blood tests to measure are total and free testosterone, hematocrit, PSA, estradiol, HDL cholesterol and others. Pre-treatment testing provides doctors with baseline values to diagnose hypogonadism (low testosterone) and assess overall health. Baseline tests are also conducted during TRT as well, ensuring that doctors can adjust TRT dose and catch side effects before they become an issue. Hematocrit Test PSA Test Estradiol Test Blood Pressure Estimated Glomerular Filtration Rate eGFR Liver Enzymes Test TSH Test Free T3 Test Total Testosterone Test Free Testosterone Test Ferritin Test HDL Cholesterol Test Click here for the Pre- TRT panel and the TRT panel (after 6-8 weeks on TRT) But do you know why these tests are needed or what they mean? Below, you’ll find some of the main blood tests that have been shown to be affected by TRT, so doctors measure them before and during therapy to prevent or manage side effects: Understanding Testosterone Blood Tests A testosterone blood test is a crucial diagnostic tool used to measure the level of testosterone in your blood. Testosterone, produced by the adrenal glands and gonads (testes in men and ovaries in women), plays a vital role in the development and maintenance of male reproductive tissues, bone density, and muscle mass. This test is commonly employed to diagnose and monitor conditions related to abnormal testosterone levels, such as hypogonadism (low testosterone) and hyperandrogenism (high androgen levels). There are several types of testosterone blood tests, each serving a unique purpose. The total testosterone blood test measures the overall amount of testosterone in your blood, including both bound and free testosterone. The free testosterone test measures the testosterone that is not bound to proteins in the blood, making it readily available to the body’s tissues. Additionally, the bioavailable testosterone test measures the testosterone that is available to the body’s tissues and is not bound to sex hormone-binding globulin (SHBG). Understanding these different tests helps in accurately diagnosing and managing conditions related to testosterone levels. Why Monitor Testosterone Levels on TRT? Testosterone replacement therapy (TRT) is a medical treatment designed to increase testosterone levels in individuals with hypogonadism. Monitoring testosterone levels on TRT is essential to ensure the treatment’s effectiveness and safety. Here are some key reasons why monitoring testosterone levels on TRT is crucial: Ensuring Normal Testosterone Levels: The primary goal of TRT is to elevate testosterone levels to within the normal range. Regular monitoring helps ensure that the treatment is effective and that testosterone levels are neither too high nor too low. Adjusting Dosage: Monitoring testosterone levels allows healthcare providers to adjust the TRT dosage as needed, ensuring optimal treatment outcomes. Identifying Side Effects: TRT can cause side effects such as acne, hair loss, and mood changes. Regular monitoring helps healthcare providers identify these side effects early and adjust the treatment plan accordingly. Monitoring Long-term Effects: TRT can have long-term effects on the body, including changes in bone density and cardiovascular health. Regular monitoring helps healthcare providers track these changes and make necessary adjustments to the treatment plan. By keeping a close eye on testosterone levels, healthcare providers can ensure that TRT is both effective and safe for the patient. Hematocrit Test Hematocrit refers to the proportion or percentage of red blood cells present in your total blood volume. Your red blood cells are responsible for transporting oxygen and nutrients throughout your body. Without enough red blood cells (a condition known as anemia), your body suffers from oxygen and nutrient deprivation. On the flip side, too many red blood cells cause high hematocrit that can turn your blood into a thick slurry that can seriously affect your circulation. A normal hematocrit for an adult male is anywhere from 42 to 54%. If your hematocrit results are lower than 41%, it means you have low proportion of red blood cells. Over 55%, and you have too many. One of the primary side effects of TRT is the production of too many red blood cells, leading to high hematocrit. High hematocrit can be lowered by blood donation or therapeutic phlebotomies (ordered by your doctor if you are not allowed to donate blood at a blood bank due to exclusion criteria). Just be careful: Do not donate blood more frequently than every 2 months since this can deplete your iron stores and make you tired. This test is included in CBC (chemistries and blood count) panel.   PSA Test Prostate-specific antigen, or PSA, is a protein that is produced in your prostate gland. It's designed to liquefy semen, which is necessary for the free swimming of sperm in ejaculate. It may also help to dissolve the cervical mucus to allow the sperm to enter the uterus for the purposes of impregnation. Normal PSA levels for men under 40 range between 0 and 2 ng/mL, while PSA levels for men older may raise slowly. A PSA test helps to detect extra-high levels of this protein. High PSA levels are the result of disruptions of the cellular structure of the prostate gland, which can be caused by a number of diseases--including cancer or an infection. Benign prostate hyperplasia, urinary retention, and prostatitis can be the cause of high PSA, but your doctor will want to monitor your PSA levels just to be sure the problem isn't a serious one. If PSA levels are high, your doctor may recommend a prostate exam or even a biopsy to determine the cause of your elevated PSA levels. TRT is contraindicated for men with PSA greater or equal than 4. Estradiol Test Estradiol is the primary female sex hormone, but did you know that the male body produces it from testosterone? It is produced in fat and liver cells from testosterone via the aromatase enzyme. Due to several factors like fat content, liver disease, medication effects and genetics, some men may produce more estradiol from testosterone than other men. New information has shown that men require a special estradiol test called sensitive estradiol test. The regular test used for women may overestimate estradiol in men due to interference of inflammatory markers like C-Reactive Protein (CRP). For the average man, estradiol levels should remain lower than 50 pg/mL, although there is little evidence of what the top of the estradiol test is in men who do not have low testosterone. If estradiol levels are higher than 50 and you start showing symptoms of high estradiol (gland growth under nipples, too much water retention), it may be necessary to take an estrogen blocker (aromatase inhibitor) . However, taking aromatase inhibitor like anastrozole should be done with careful monitoring of sensitive estradiol blood test since overdosing can cause health issues in men. A few of the reported effects of low estradiol levels include: joint pain, eye fatigue, loss of erections, limited sensitivity in the penis, sleepiness, and excessive urination. Long term low estradiol can decrease bone density. A few of the reported effects of high estradiol levels (in the presence of low testosterone) include: soft erections, water retention, excessive sweating, insomnia, bloating, hot flushes, brain fog, and high blood pressure. Blood Pressure The term "blood pressure" refers to the pressure in your arteries during the beating of your heart. There are two numbers: 1) The top number, or systolic, tells you the pressure in your arteries when the muscles of your heart contract. 2) The bottom number, or diastolic, tells you the pressure in your arteries when your heart relaxes and refills with blood in the pause between heartbeats. Healthy blood pressure is lower than 120/80. If your blood pressure rises anywhere from 121/81 to 139/89, you are pre-hypertensive. Crack 140/90, and you suffer from hypertension. Anyone over 180/100 is in serious hypertensive crisis. TRT can increase water retention, sodium uptake and hematocrit is some men, factors that can increase blood pressure. If your blood pressure rises too much, it can place excess strain on your blood vessels and potentially cause a crack. Should the blood vessels crack, the resulting clotting (your body's attempt to stop internal bleeding) can interfere with healthy blood flow--potentially leading to heart attacks, strokes, peripheral arterial disease, and other cardiovascular problems. Estimated Glomerular Filtration Rate eGFR Your glomerular filtration rate (GFR) is an indication of your kidney function. The higher your GFR, the more blood passes through the glomeruli (the filters in your kidneys that remove waste from your blood) every minute. A healthy GFR is anywhere from 90 to 120 mL/min/1.73 m2. Senior citizens will often have lower GFR levels, due to the fact that kidney function decreases with age. Note: It's important to understand that each lab has its own measurements, so what is "healthy" to some may be low with others. If your GFR drops below 60 and remains at that low level for more than 3 months, it's an indication of chronic kidney disease. Liver Enzymes Test Your liver is responsible for a number of important functions, such as breaking down nutrients, producing the proteins that clot your blood, and eliminating toxins. The enzymes produced by your liver are responsible for carrying out these functions. However, if the liver suffers damage, those enzymes tend to leak into your bloodstream. High levels of liver enzymes are a good indicator that your liver has been damaged ALT and AST are the two most common liver enzymes. AST should be anywhere from 10 to 40 units per liter of blood, and ALT should be from 7 to 56 units in every liter of blood. Be aware that exercise may increase these two enzymes in a non-clinically significant way. Only oral testosterone replacement has been shown to increase liver enzymes. TSH Test Thyroid-stimulating hormone, or TSH, is a hormone produced by your pituitary glands in order to stimulate your thyroid gland to produce T3 and T4 hormones. These thyroid hormones play a role in your body's metabolic function. Normal TSH levels should be between 0.5 and 3.5 U/ml (different guidelines show different upper TSH levels). Many educated doctors test for free T3 and free T4 (the unbound thyroid hormones) when TSH is over 3 since they believe this will provide a better picture of thyroid health. If TSH levels are low, it's an indication of hyperthyroidism. If TSH levels are very high, it's an indication of hypothyroidism. Free T3 Test Free T3 refers to unbound T3 (thyroid) hormone in your bloodstream. T3 is the more important of the thyroid hormones, but it can only be produced from T4. This means your body needs to produce T4 then turn it into T3. Once the T3 is unbound from the protein molecules, it can then be used by your body to stimulate metabolic function in all your cells. Normal Free T3 levels are anywhere from 230 to 620 pg/d. If free T3 is low, your doctor may test for thyroid antibodies to ensure that you do not have an autoimmune disease called Hashimoto's. Total Testosterone Test Total testosterone test measures refer to all of the testosterone circulating in your body. Some testosterone circulates freely, while some is bound to protein molecules. The whole point of TRT is to increase your testosterone levels. A normal testosterone range is anywhere from 350 to 1070 ng/dL. Low testosterone can cause low mood, sex drive, fatigue and other symptoms. In some men, too much testosterone in the body can lead to excessive estradiol, acne, oily skin, hair loss, testicular shrinking, and increased blood viscosity due to high red blood cells. Free Testosterone Test Free testosterone refers to the testosterone circulating in your body that is NOT bound to protein molecules like albumin and sex hormone binding globulin. It is believed that your body is more easily able to use free testosterone. It usually runs at about 2 percent or higher of total testosterone. Testosterone Test Results and Interpretation Testosterone test results are typically reported in nanograms per deciliter (ng/dL). The normal range for testosterone levels varies depending on age, sex, and the laboratory performing the test. Here are some general guidelines for interpreting testosterone test results: Normal Testosterone Levels in Adult Men: 300-1,000 ng/dL Normal Testosterone Levels in Adult Women: 15-70 ng/dL Low Testosterone Levels: Less than 300 ng/dL in men or less than 15 ng/dL in women High Testosterone Levels: Greater than 1,000 ng/dL in men or greater than 70 ng/dL in women It’s important to note that testosterone levels can fluctuate throughout the day and may be influenced by various factors such as sleep, stress, and exercise. Therefore, a single testosterone test result may not provide a complete picture of an individual’s overall testosterone levels. Healthcare providers may recommend repeat testing to confirm the results and monitor changes in testosterone levels over time. Understanding your testosterone test results and their implications can help you and your healthcare provider make informed decisions about your treatment plan. Ferritin Test Ferritin is a protein that is responsible for storing iron and releasing it when your body needs to produce red blood cells. If you suffer from an iron deficiency, your ferritin level are likely to be low. Ferritin levels also fall when you give blood (a common method of lowering hematocrit). Normal ferritin levels for men is anywhere from 30 to 300 ng/mL. However, if ferritin levels are too low (after a blood donation), your body is unable to store iron, meaning it will not be able to produce new red blood cells. If you are considering donating blood to lower your hematocrit, it's a good idea to check your ferritin levels first. Your body needs enough of this protein to reproduce the red blood cells you are donating HDL Cholesterol Test High density lipoprotein, also known as HDL cholesterol, is the "good" type of cholesterol. It's responsible for counteracting the effects of low-density lipoprotein, or LDL cholesterol. Low HDL and high LDL may lead to a wide range of cardiovascular problems, including blocked arteries, stroke, heart attack, and peripheral arterial disease. According to experts, even a 5 mg/dL decrease in HDL cholesterol can increase your risk of coronary heart disease by as much as 25% Normal HDL cholesterol levels are anything above 40 mg/dL. Unfortunately, decreased HDL is a known side effect of TRT in some men using higher testosterone doses. Your doctor will monitor HDL cholesterol via a lipid panel in order to ensure that you are not at risk for heart disease. Educate yourself about testosterone replacement side effects 

  Bodybuilding is a tough sport and requires a lot of work and dedication, especially when it comes to maximizing benefits and minimizing side effects of testosterone and anabolic androgenic steroids (AAS). With the right training and nutrition, you can gain muscle, lose fat and get stronger. But you have to keep an eye on your health through chosen lab tests and panels, especially when there are obstacles to care brought by stigma and medical professionals’ judgment. Proper nutrition, supplementation, and adequate rest are crucial for effective muscle recovery and overall training success. Insufficient recovery can lead to issues like overtraining and decreased performance. In this article we will talk about harm reduction and list 14 lab tests and panels for bodybuilders to stay healthy while improving body composition and strength. Bodybuilders who use testosterone and anabolic androgenic steroids (AAS) need to be smart about maximizing benefits and minimizing short-term and long-term side effects while exercising and eating well for muscle gain, fat loss, and quality of life. Anabolic hormones like growth hormone, testosterone, and insulin are key to muscle growth and strength training. This way they can get the most out of their testosterone and AAS use. Reduced harm is important, especially when there are obstacles to care like stigma and criticism from medical professionals. Understanding Blood Tests for Bodybuilders Blood tests are a crucial tool for bodybuilders to monitor their health, track their progress, and optimize their training and nutrition strategies. By understanding the importance of blood tests, bodybuilders can make informed decisions about their training and nutrition, and avoid potential health risks. Importance of Blood Tests Blood tests provide valuable insights into a bodybuilder’s overall health and fitness level. They can help identify potential issues with hormone balance, overtraining, and nutrition, and provide a baseline for tracking progress over time. Regular blood tests can also help bodybuilders detect any underlying health disorders that could affect their performance. For instance, a comprehensive metabolic panel can reveal imbalances in glucose levels, kidney function, and liver enzymes, which are critical for maintaining optimal health during intense training. By regularly monitoring these markers, bodybuilders can adjust their training and nutrition strategies to ensure they are supporting their muscle growth and overall health. Bodybuilder Tests: Here are 14 lab tests and panels to keep you healthy while improving body composition and strength: Take blood sample after waking and before intense physical activity for accurate testing of specific health markers for male bodybuilders and weightlifters. Complete blood count (CBC) Here are the components of your blood that are measured by a complete blood count (CBC) test panel: red blood cells which carries oxygen; white blood cells which fights infection; hemoglobin which is the protein in red blood cells that carries oxygen; hematocrit which is the ratio of red blood cells to the fluid component in your blood (which correlates with blood thickness); and platelets which aids in blood clotting. All androgens including testosterone and anabolic androgenic steroids (AAS) can increase red blood cells and its proportion in the blood (hematocrit) thus increasing blood thickness (polycythemia). High hematocrit is associated with cardiovascular disease, high blood pressure and headaches. This panel is important because it will tell you if you have reached 53 hematocrit which means you need to donate blood or undergo therapeutic phlebotomy. Given the physical demands of intense training it’s important to monitor health markers like kidney and liver function through regular blood tests to prevent overstraining the body. Tests included in the CBC panel: White blood cell count (WBC or leukocyte count) WBC differential count Red blood cell count (RBC or erythrocyte count) Hematocrit (Hct) Hemoglobin (Hgb) Mean corpuscular volume (MCV) Mean corpuscular hemoglobin (MCH) Mean corpuscular hemoglobin concentration (MCHC) Red cell distribution width (RDW) Platelet count Mean Platelet Volume (MPV) Complete Metabolic Profile (CMP) The complete metabolic profile, also known as CMP panel, is a medical screening test that consists of 14 blood tests and is used to assess overall health. CMP blood test panel checks fluid and electrolyte balance, glucose level, kidney and liver function and electrolyte levels. FASTING IS REQUIRED. Tests: Glucose Sodium Potassium Chloride Carbon Dioxide Calcium Protein Albumin Alanine transaminase (ALT) Aspartate transaminase (AST) Bilirubin Alkaline phosphatase (ALP) Blood urea nitrogen (BUN) Creatinine eGFR Lipid Profile This panel includes LDL which is known as “bad cholesterol”, HDL which is known as “good cholesterol” and triglycerides (fatty acids in the blood). Higher dose of T or AAS may increase LDL cholesterol and decrease HDL cholesterol and triglycerides. Significant drop in HDL may lead to cardiovascular problems in the long run. FASTING IS NEEDED. Cystatin C and EGFR Kidney Tests Cystatin C is a more accurate way of measuring kidney function in individuals with higher muscle mass. This is because factors like increased muscle mass, protein intake and creatine supplementation can affect the use of creatinine as the primary variable. Cystatin C is more reliable. Estimated glomerular filtration rate is another parameter used to assess kidney function (eGFR). The rate at which fluid is filtered through the kidney is called glomerular filtration rate. Creatinine clearance rate, also known as CCRCr or CrCl, is a good estimate of glomerular filtration rate (GFR). It is the volume of blood plasma cleared of creatinine per unit of time. eGFR below 60 may indicate kidney function problems. GGT Liver Test The gamma-glutamyl transpeptidase (GGT) blood test looks for an enzyme or protein by that name in your blood. GGT stands for gamma-glutamyl transpeptidase. GGT is present in the cells of the liver. Your doctor can use this test to check for liver damage or the ducts that drain it. If the results of another blood test, alkaline phosphatase, is abnormal this test can also help to differentiate between liver diseases and bone diseases. Higher than normal results may indicate liver damage from diseases like hepatitis, cirrhosis, tumors or pancreatic cancer. GGT is not affected by resistance training unlike other liver enzymes in the CMP like AST and ALT. So using GGT is a more accurate way to know if a bodybuilder has liver disease. Total testosterone was measured by liquid chromatography/mass spectrometry and free testosterone by equilibrium ultrafiltration. Since the standard total testosterone test by immunoassay has a ceiling of 1,500 ng/dL, men with high testosterone cannot use the test. Testosterone replacement therapy (TRT) in bodybuilding can have significant implications, especially when combined with intense training and anabolic steroid use. It is crucial to be aware of the health risks associated with TRT and to conduct regular blood tests to monitor hormonal and health changes. Measuring luteinizing hormone (LH) along with testosterone is important to understand hormonal imbalances and optimize training and supplementation. The LC/MS test for testosterone has no ceiling. Some labs also provide calculated free testosterone instead of equilibrium ultrafiltration-based one which is more accurate for this value. Ultra-Sensitive Estradiol (E2) Test The estradiol level may be overestimated by the test used. This test uses immunoassay technology which cannot distinguish between C-Reactive Protein (involved in inflammation) and estradiol; so it interprets the combination of the two as estradiol. This ultrasensitive estradiol test uses assay technology called liquid chromatography/mass spectrometry (LC/MS) which is not limited by the above mentioned limitation. DHT analogs like oxandrolone can significantly lower estradiol levels which can cause joint pain and other problems related to low estradiol. Notice that only 0.4% of total testosterone is converted to estradiol during aromatization. The body does this to counteract the beneficial effect of estradiol on lipids which is a result of testosterone’s negative effect on lipids. When your total testosterone is high your estradiol will also be high. When you assume an aromatase inhibitor is needed you should be very careful.

Prolactin Test Prolactin levels are a concern for many bodybuilders because of the correlation with erectile dysfunction. DHT Test This test measures the amount of dihydrotestosterone (DHT) in the blood. In some men excessive levels of dihydrotestosterone (DHT) is linked to acne, hair loss and benign prostatic inflammation while low levels is linked to low libido. IGF-1 Test Insulin-like Growth Factor 1, also known as IGF-1 is measured to determine the amount of human growth hormone in the blood. This hormone controls the growth and metabolism of glucose and is produced by the liver and other tissues. Lack of IGF-1 will prevent muscle growth. Ferritin Test Iron is stored in the body via ferritin. Iron is needed for the formation of red blood cells which carries oxygen throughout the body. Lack of ferritin in the blood is anemia. TRT and anabolics increases the production of red blood cells in the body (erythrocytosis). Because of the increased production, iron reserves and ferritin levels decreased. Additionally, thyroid hormones play a crucial role in regulating metabolism, energy levels, and body composition, which are essential for bodybuilders. Testosterone decreases ferritin. Men who are on TRT or anabolics and have high hematocrit (thick blood due to TRT or anabolics) often donate blood or undergo phlebotomy. Every time you donate blood ferritin level drops by about 30 points on average. Low ferritin can cause various symptoms including tiredness, muscle aches and restless leg syndrome. Monitoring thyroid-stimulating hormone (TSH) is also important as part of a comprehensive evaluation of thyroid function for bodybuilders. TSH levels can significantly impact metabolism, energy levels, and overall performance. Hormones and Muscle Growth Hormones play a critical role in muscle growth and development. Understanding the role of hormones in bodybuilding can help bodybuilders optimize their training and nutrition strategies to promote muscle mass. Role of Hormones in Bodybuilding Hormones such as testosterone, growth hormone, and insulin-like growth factor-1 (IGF-1) are essential for muscle growth and development. Testosterone, in particular, is a key anabolic hormone that drives muscle growth and development in men. It promotes protein synthesis, which is crucial for muscle repair and growth after intense training sessions. Growth hormone and IGF-1 also play significant roles by stimulating muscle cell growth and increasing the uptake of amino acids into muscle cells. For women, oestrogen and growth hormone are important anabolic hormones that support muscle growth and development. By understanding the functions of these anabolic hormones, bodybuilders can tailor their training and nutrition strategies to maximize muscle mass and enhance performance. Blood Test Results Blood test results can be confusing especially for bodybuilders who are not familiar with medical terms. But understanding these results is key to making informed decisions on training and nutrition. A full blood test panel will give you insights on overall health and fitness including muscle growth, hormone levels and kidney function. By reading these results bodybuilders can adjust their training and nutrition plan to maximize performance and minimize health risks. Results When reading blood test results, always refer to the normal reference ranges for each biomarker. For example a testosterone level of 300-1000 ng/dL is normal for adult male. If the result is out of this range it means there’s an underlying issue that needs to be addressed. Bodybuilders should consult a healthcare professional to interpret their blood test results and create a plan to adjust their training and nutrition. This way any abnormality will be identified and managed immediately and overall health and performance will be supported. Nutrition in Bodybuilding Nutrition is a big part of bodybuilding and blood tests can give you insights on nutritional deficiencies or imbalances. A full metabolic panel can measure biomarkers such as glucose, electrolytes and liver enzymes which can tell you how well your body is utilizing nutrients. By knowing these markers bodybuilders can adjust their diet to make sure they are getting the necessary nutrients for muscle growth and recovery. How Blood Tests Affects Nutrition Decisions Blood tests can affect nutrition decisions by identifying potential deficiencies or imbalances. For example low vitamin D means you need to supplement or increase sun exposure. High cortisol means you need to reduce stress or adjust training and nutrition. By using blood test results to guide nutrition decisions bodybuilders can optimize their diet and training plan to support muscle growth and recovery. Blood tests can also help identify nutritional deficiencies that impact muscle recovery, emphasizing the importance of proper nutrition, supplementation, and adequate rest for effective muscle recovery and overall training success. This proactive approach will keep you at peak performance and overall health. Common Nutrient Deficiencies Nutrient deficiencies can negatively impact muscle growth and recovery. Common nutrient deficiencies in bodybuilders include iron, vitamin D, and magnesium deficiencies. Iron is essential for transporting oxygen to the muscles, which is vital for energy production during workouts. Vitamin D and magnesium are important for muscle function and recovery, helping to prevent muscle cramps and promote muscle relaxation. Protein is also essential for muscle growth and repair, but excessive intake can cause kidney damage. By regularly monitoring nutrient levels through blood tests, bodybuilders can identify deficiencies early and adjust their diet or supplementation accordingly. This proactive approach ensures that they are getting the necessary nutrients to support muscle growth, recovery, and overall health. By understanding the importance of blood tests and the role of hormones in bodybuilding, bodybuilders can make informed decisions about their training and nutrition strategies to optimize their performance and promote muscle growth. Regular blood tests can help bodybuilders detect any underlying health disorders and avoid potential health risks, ensuring that they can continue to train and compete at their best. How Often to Get Blood Tests Frequency and timing of blood tests depends on individual goals and circumstances. Bodybuilders on hormone replacement therapy (HRT) or anabolic steroids need to get blood tests more frequently to monitor hormone levels and potential side effects. Monitoring helps to adjust dosages and prevent adverse effects so that the benefits of these therapies are maximized while minimizing risks. How Often Should Bodybuilders Get Blood Tests? As a general rule bodybuilders should get blood tests at least once a year to monitor overall health and fitness. But bodybuilders on HRT or anabolic steroids should get blood tests every 3-6 months to monitor hormone levels and potential side effects. Bodybuilders who are experiencing symptoms like fatigue, muscle weakness or joint pain should get blood tests more frequently to identify underlying issues. Blood testing is a proactive measure to ensure any health concern is addressed immediately and long term health and performance is supported.
