Drostanolone, or dromostanolone, is an anabolic–androgenic steroid (AAS) of the dihydrotestosterone (DHT) group which was never marketed. An androgen ester prodrug of drostanolone, drostanolone propionate, was formerly used in the treatment of breast cancer in women under brand names such as Drolban, Masteril, and Masteron. This has also been used non-medically for physique- or performance-enhancing purposes.

Drostanolone, also known as 2α-methyl-5α-dihydrotestosterone (2α-methyl-DHT) or as 2α-methyl-5α-androstan-17β-ol-3-one, is a synthetic androstane steroid and a derivative of DHT. It is specifically DHT with a methyl group at the C2α position.
