But I do not think anyone (including me) has really gotten a lab test panel like this one before and after a few weeks of using 500 IU hCG three times per week, a dose that has been shown to increase at least OH-17-progesterone in men on TRT. I just went through an oral pregnenolone experiment and now about to do one with hCG + TRT to measure its effect on upstream hormones.
