Bolasterone
Bolasterone ( INN, USAN) (brand names Myagen, Methosarb) is a 17α- alkylated anabolic steroid. It has close structural similarity to testosterone, and like methyltestosterone has a methyl group at C17 in order to increase oral bioavailability. In addition, it is also 7α- methylated, similar to its 7β-methylated isomer calusterone.
