4-Androstenediol is an androstenediol that is converted to testosterone. The conversion rate is about 15.76%, almost triple that of androstenedione, due to utilization of a different enzymatic pathway. There is no direct conversion to estrogen, though some secondary aromatization does occur through metabolism. 4-Androstenediol is less androgenic, since it does not metabolize into the potent androgen dihydrotestosterone (DHT).[citation needed]

4-Androstenediol is closer to testosterone structurally than 5-androstenediol, and has androgenic effects.

[edit] Medical and commercial use

Patrick Arnold holds a 1999 patent on "Use of 4-androstenediol to increase testosterone levels in humans".[1]
