If your free testosterone is between 100-250 Pg/ml you should be fine, same thing with your bioavailable testosterone if it lies in the 10-20 ng/dl range, those are what really count. Alas most labs never seem to test for free-testostosterone, which is stupid, because those and estradiol(E2) are what matters in finding hyponadism and androgenic decline, not neccesarily total testosterone. Just looking at my testosterone levels, one would think i'm hypogondic, however i'm not since my serum testosterone/SHBG quota is 1.5, and according to a calculator my free testosterone and bio-available should be just above average, however i still don't feel that way. This one problem with labs, they don't use the right tools to diagnose people, a simple SHBG+Albumin+serum testosterone level might give you an idea of your FAI, but not your free testosterone levels, which is what they should be looking at when evaluating these cases.
