1-Androsterone

Androsterone (ADT)  is a testosterone metabolite that is secreted in sweat and excreted in urine.  It’s a reputed pheromone and weak androgen.  1-Androsterone has a double bond at C-1, and is alleged to be a prohormone for 1-testosterone, a potent anabolic steroid and Schedule III controlled substance.  Unlike the now-banned prohormones, however, more than one enzymatic step is required to convert 1-androsterone to the target hormone.
