Bolasterone (INN, USAN) (brand names Myagen, Methosarb; former developmental code names NSC-66233; U-19763), also known as 7α,17α-dimethyltestosterone, is a 17α-alkylated anabolic-androgenic steroid (AAS) that is used in veterinary medicine. It has close structural similarity to testosterone, and like methyltestosterone has a methyl group at C17α in order to increase oral bioavailability. In addition, it is also 7α-methylated, similar to its 7β-methylated isomer calusterone.
