Thinking about purchasing a testosterone booster? Can you recognize a sham product from a real product? (Hint: you can’t trust online reviews) If you’re currently taking one of these products or considering taking one, this is a must-read.

 

You know those commercials with Frank Thomas touting a testosterone boosting supplement, where at the end Frank always says, and trust me, she’ll love it, too. Spoiler Alert: she’ll only love it if it works. So, how do you know if it works? You click here and read our latest post.

 

A recent study looks at the five most popular testosterone boosters on planet Amazon. What they discover will definitely shock you. And on a side note, if you’re using one of these products, I’ve got some beautiful Florida swampland for sale.

 

We all know that testosterone levels decline with age, making many men feel like they are not “themselves 100%”.  Some men feel like grasping at straws and are in constant search for a non-prescription over the counter supplements to boost their testosterone.

 

But what you need to know about testosterone boosters is that beyond the hype and the slick marketing campaigns tugging at men’s wallets, there’s little proof that they actually work.

 

According to a recent analysis of popular online testosterone boosting supplements, the evidence of any positive impact on testosterone levels is sorely lacking.[1]

 

The study looked at five popular testosterone boosters:

 

  1. Prime Labs Manufactured by Prime Labs
  2. Alpha Boost Manufactured by Invictus Labs
  3. Extra Strength Manufactured by Dr. Martin’s Nutrition
  4. Iron Brothers Manufactured by Iron Brothers Supplements
  5. Pro-T Manufactured by Prometheus Wellness LLC

 

Researchers chose these five testosterone boosting products because they represent the top five testosterone booster supplements based on cost, ingredient profile, and Amazon reviews. In other words, these are the best of the bunch and are likely products you’re familiar with.

 

Amazon Unwittingly Contributes to Testosterone Boosting Supplement Scam

 

Let’s first look at exactly how these five products were chosen. Researchers searched the Amazon marketplace database using keywords “testosterone” + “booster” with default search settings and ranking items based on relevance.

 

According to the study, “The top 5 T-Boosters identified on July 22, 2018, were reviewed based on price, ratings, reviews, manufacturer details, and ingredients. Consumer reviews were categorized using core themes in the Androgen Deficiency in the Aging Male (ADAM) questionnaire as a proxy to understand T-Booster efficacy and reanalyzed following filtration of untrustworthy comments using ReviewMeta.com, a proprietary Amazon customer review analysis software.”

 

Why is that last part important? As some of you probably know, merchants have wised up to the fact that the way to win on Amazon regardless of the product being sold is to “get” great reviews from “customers”. The problem is that merchants have also realized that these great reviews can come from the companies themselves in a scam known as “brushing”.

 

In a nutshell, brushing is when companies send out products to people who didn’t order them then write reviews themselves using the unsuspecting consumers’ names. How much is a great review worth on Amazon? A heck of a lot more than the free products these scam companies are sending out, which is why those conducting this analysis sought to exclude those types of reviews.

 

What percentage of reviews were determined to be scam reviews? A little more than 66 percent. Which means if you’re one of the men who decided to purchase a testosterone booster based on customer reviews, you were more likely to be reading fiction rather than facts.

 

The average review score for these five products was 4.56 out of 5. However, after filtering the reviews through ReviewMeta.com, here is the impact:

 

  • 91 percent decrease in users reporting an increase in libido
  • 59 percent decrease in reports of increased energy
  • 93 percent decrease in reports of improved strength/endurance
  • 60 percent decrease in reports of improved erections
  • 67 percent decrease in reports of improved sleep
  • 89 percent decrease in reports of improved sports ability

 

10 Most Common Ingredients in Testosterone Boosters

 

The 10 most common ingredients in the five testosterone boosters studied were:

 

  1. Tongkat Ali Extract
  2. Horny Goat Weed
  3. Saw Palmetto Extract
  4. Boron
  5. Nettle Extract
  6. Maca Root Powder
  7. Ashwagandha Root Extract
  8. Fenugreek
  9. Bioperine
  10. DIIM (Diindolylmethane)

 

It should be mentioned that some of these herbs have real health benefits, but as the authors of this analysis discovered in their research, raising testosterone levels likely isn’t one of them.

 

Of these 10 most common ingredients, there were a total of 191 studies conducted. However, after further review, researchers found that only 19 percent involved human subjects.

 

Among those 37 studies that did use human subjects:

 

  • 30 percent showed an increase in testosterone levels
  • 3 percent showed a decrease
  • 46 percent showed no effect
  • 22 percent were indeterminate

 

Of the five popular testosterone boosters studied, three do not include the amount of each ingredient on their labeling and four of the five had the exact same ingredients in the exact same quantities. And all five refer to being produced in an “FDA registered facility”, which is half a world away from being “FDA approved”.

 

The takeaway – marketing matters, also known as duping an unsuspecting population of men desperately searching for solutions to their low testosterone levels.

 

Researchers of this study came to a similar conclusion, citing that their findings “raises questions as to the authenticity of both on-bottle marketing as well as reviews touting the benefits of these products,” and offers this bit of advice for men seeking therapeutics to raise their testosterone levels:

 

“In the absence of additional human studies, patients should be cautioned before considering T-Boosters, given the availability of highly effective Food and Drug Administration approved therapies.”

 

Another recent study looking at misleading labeling claims by supplement manufacturers found that “One such product, a purported testosterone

booster, potentially mislead consumers by misusing and exaggerating scientific information.”[2]

 

Regarding the testosterone booster in question, the report’s author sent an email to the manufacturer requesting information that would back up their marketing claims. However, what he received back from the company did not support those advertising claims in any way, shape, or form.

 

The company specifically sent back three scientific articles and an Evidence and Safety Summary Report. The key ingredient in question, and the one reportedly most responsible for increasing testosterone levels, is D-aspartic acid.

 

The first study the company sent back was on rats, not humans, and therefore dismissed. The second was a summary of D-aspartic acid’s role on the nervous and endocrine systems of mammals (not necessarily humans) but never looks at whether testosterone levels were increased.

 

The third scientific article the company sent back, according to the study’s author, was the “only bona fide attempt at providing evidence for this product’s efficacy claims” and reports on the role and molecular mechanism of D-aspartic acid in the release and synthesis of luteinizing hormone (LH) and testosterone.

 

The fourth document – the Evidence and Safety Summary Report – was simply a summary of the three previously mentioned studies plus eight additional studies, which also did “not provide any information to support the product’s testosterone boosting claims.”

 

After scouring medical journals using the terms “D-aspartic acid” + “testosterone” here is what the author of the study found:

 

  • There is no research on the effects of D-aspartic acid on human testosterone
  • There is no evidence that supports the manufacturer’s claims that D-aspartic acid can boost testosterone levels
  • There is evidence that people use it for the absorption of supplements and athletic performance.

 

Evidence that people use it for the absorption of supplements and athletic performance. Not evidence that it has any effect on both.

 

Misleading Labels don’t Mislead, They Outright Deceive

 

The study’s author writes that according to the marketing and manufacturer’s label, this “product can increase, support, stimulate, amplify, and boost testosterone levels. Additional claims are that the product has been clinically researched and that its results are clinically proven.”

 

Now, does that sound like misleading consumers or pure fiction when compared to what the researcher actually found for the T-booster’s key active ingredient – D-aspartic acid?

 

The study’s author cites a few critical reasons why the product manufacturer’s claims are misleading:

 

  1. A misuse of scientific information – one study involved men with the lowest of testosterone levels (far below average) that were increased slightly but not enough to have a discernible effect.

 

  1. One study cited used a different product; not the manufacturer’s testosterone booster, which had different ingredients.

 

  1. One study contradicted several other studies on D-aspartic acid, all of which showed inconclusive results on its ability to increase testosterone.

 

  1. A misuse of the product label’s bar graph – the graph shows only the upper half of the results, which essentially exaggerates the difference between the experimental and placebo groups.

 

The study’s author also notes that “The advertiser did not mention the decline in the participant’s total testosterone three days after the suspension of D-aspartic acid.”

 

The study’s conclusions are cautionary at best when it comes to advertising claims like ‘100% clinically validated’ and ‘clinically researched’, as “the consumer could infer that the product has been subjected to relevant, unbiased and independent clinical trials, that it is safe and effective, and that there is sufficient scientific evidence to support these claims.”

 

But as we’ve learned here today, you can’t believe everything you hear and read, especially when someone is trying to sell you something. Are the days of snake oil salesmen a thing of the past, or has the game and deception just evolved?

 

The only way to truly know if a testosterone boosting therapy works beyond plavebo effect is to get a testosterone blood test, both before and after a few days. This is the first step. Otherwise, you’re just guessing about the efficacy, while simultaneously flushing money down the toilet if a therapy isn’t working. Some supplements may even have liver or kidney issues. Remember: The FDA has no time to test and regulate these supplements.
