Bolasterone (Myagen) is an anabolic-androgenic steroid that is similar to methyltestosterone. It is very estrogenic and can be used for decent off-season growth but has fallen from popularity. The synthetic steroid was first described in 1959 and subsequently introduced by Upjohn under the trade name Myagen.
Bolasterone was prescribed primarily for the treatment of advanced breast cancer. It was only marketed for a few years in the 1960s before it was discontinued. Bolasterone reappeared on the black market and was used by bodybuilders in the 1980s. The drug quickly disappeared from the marketplace until it reemerged in the 2000s and was produced by some underground labs (UGLs) such as Geneza Pharmaceuticals.
Bolasterone is the chemical name of active ingredient in Myagen. Myagen is a registered trademark in the United States and/or other countries.
