user, you need help to interpret those studies. SHBG binds to sex hormones and prevents them from performing their function in cells. The increase in testosterone is due to high levels of SHBG binding to sex hormones and signaling the brain that bioavailable Testosterone is low, and the difference between Free Test across all groups is negligible, all being within margin of error and nowhere near big enough to make a physiological difference. Besides, IGF proteins help you get fucking swole and the 9% lower values in vegan men are significant. However as all things that imply in cell multiplication, it also implies a higher risk of cancer. Besides, what's with all the vegan shilling?
