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]
