Bolazine

Bolazine (INN), also known as 2α-methyl-5α-androstan-17β-ol-3-one azine, is a synthetic androgen/anabolic steroid (AAS) of the dihydrotestosterone (DHT) group which was never marketed.[1] It is not orally active and is used as the ester prodrug bolazine capronate (brand name Roxilon Inject) via depot intramuscular injection.[1] Bolazine has a unique and unusual chemical structure, being a dimer of drostanolone linked at the C3 position of the A-ring by an azine group, and reportedly acts as a prodrug of drostanolone.[2]
