Oxabolone
Oxabolone is a synthetic anabolic-androgenic steroid of the nandrolone group which was never marketed. It can be formulated as the cipionate ester prodrug oxabolone cipionate, which, in contrast, has been marketed for medical use.
Oxabolone is on the World Anti-Doping Agency's list of prohibited substances, and is therefore banned from use in most major sports.
The 17α-methylated analogue of oxabolone is methylhydroxynandrolone and the 17α- and 19-methylated derivative of oxabolone is oxymesterone.
