This is Sarah Adair's second conversation, and it's the one a lot of men have been waiting for. She covers everything that should be in a men's hormone blood panel — total testosterone, free testosterone, sex hormone binding globulin, estradiol, thyroid, cortisol, and why most of those numbers mean less than you think in isolation.
She also breaks down why the standard every-two-weeks intramuscular injection protocol creates exactly the peaks and crashes it's supposed to prevent, why estrogen in men is mostly not the problem people think it is, what actually happens to fertility on testosterone replacement and how to protect it, and what's behind the broader decades-long decline in male testosterone levels.
If you've ever been told your labs are "within normal range" and still felt like garbage, this one is for you.
