Drostanolone (trade name Masteron) is an anabolic/androgenic steroid. It is known to be highly androgenic and mildly anabolic. It is incapable of aromatization and has similar properties to dihydrotestosterone. It has been successfully used as a breast cancer drug but because of the high risk of virilization safer options are prescribed.

[edit] Use in sports

Masteron is used primarily by athletes who need to retain strength while losing mass. It is beneficial to runners and athletes who must remain in a certain weight class. It has gained popularity in the bodybuilding community as a diuretic and muscle defining drug.

[edit] Trivia

Ultimate Fighting Championship athlete Hermes Franca tested positive for use of Drostanolone following his July 7th 2007 lightweight championship bout against title holder Sean Sherk.
