Oxabolone
Oxabolone
Chemical compound
Oxabolone is a synthetic anabolic-androgenic steroid (AAS) of the nandrolone (19-nortestosterone) group which was never marketed.[1][2][3] It can be formulated as the cipionate ester prodrug oxabolone cipionate, which, in contrast, has been marketed for medical use.[1][2][3]
Oxabolone is on the World Anti-Doping Agency's list of prohibited substances,[4] and is therefore banned from use in most major sports.
The 17α-methylated analogue of oxabolone is methylhydroxynandrolone (4-hydroxy-17α-methyl-19-nortestosterone) and the 17α- and 19-methylated derivative of oxabolone is oxymesterone (4-hydroxy-17α-methyltestosterone).[1][2][3]
