Methandriol bisenanthoyl acetate
Methandriol bisenanthoyl acetate, or methylandrostenediol bisenanthoyl acetate, also known as 17α-methylandrost-5-ene-3β,17β-diol 3β,17β-di, is a synthetic, injected anabolic–androgenic steroid and a 17α-alkylated derivative of 5-androstenediol. It is an androgen ester—specifically, the C3β,17β di ester of methandriol —and acts as a prodrug of methandriol in the body. Methandriol bisenanthoyl acetate is administered by intramuscular injection and, relative to methandriol, has an extended duration via this route due to a depot effect afforded by its ester.
