Drostanolone propionate (also called Masteron) is an anabolic/androgenic steroid which is the propionate ester of drostanolone. It is known to be androgenic and 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.
