In this study they point out DHT is both metabolized in blood and peripheral tissue, and that 3a-doil is reversible by reduction/oxidation, which we already knew it wasn't reversible by 5-ar. It's a great study, I wish they went further to include aromatase, but......blood conversion is stated at 4%


Dihydrotestosterone is a peripheral paracrine hormone
