This panel includes: Testosterone, Total, LC/MS and Free (Equilibrium Dialysis), and 17-OH-progesterone, a metabolite that has been correlated with sperm production.

Testosterone Replacement Therapy (TRT) shuts down upstream hormones like LH and FSH required for sperm production, so men on TRT generally have a difficult time fathering a child. Some studies show that adding hCG to a TRT protocol may improve sperm production since hCG is an analog of LH that could stimulate sperm production. But optimizing hCG dose and frequency based on sperm count can be a time consuming process since it takes at least 8 weeks to see changes in sperm tests. Fortunately, there is an easier way by measuring 17-OH-progesterone to predict the efficacy of the hCG+TRT protocol without having to wait for 8 weeks between hCG dose/frequency changes. 

This panel contains testosterone and its downstream metabolites: Estradiol and DHT. All three hormones are measured using Liquid Chromatography/Mass Spectrometry (LC/MS), the most accurate assay for hormones. No interactions with supplements like biotin are present.

This blood donation panel includes these tests: Hematocrit, iron & total iron binding capacity (TIBC), and ferritin.This panel is designed to determine if: 1- Your blood donation or therapeutic phlebotomy was effective in lowering your high hematocrit without negatively affecting ferritin or iron. 2- It is safe to do another blood donation or therapeutic phlebotomy depending on ferritin or iron levels.

This panel includes the two gold standard tests for estradiol and testosterone (Total and Free) that use liquid chromatography/ mass spectrometry for best accuracy and no interactions.

This panel provides smart bodybuilders with information that can help minimize potential short- and long-term side effects and risks. This basic bodybuilder panel includes the following gold standard tests/panels: Cystatin C (the only accurate kidney function test for bodybuilders), hematocrit (blood viscosity factor), CMP (glucose, liver & kidney function, and electrolytes), total and free testosterone (LC/MS assay—no upper limit and no interference with anabolics), ultra-sensitive estradiol (the only accurate estradiol test for men), & lipid cholesterol panel. Fasting is required.
