Oxofluoxymesterone

Oxofluoxymesterone (developmental code name U-6596), or ketofluoxymesterone, is an androgen and anabolic steroid (AAS) which was never marketed.[1][2][3] It was assessed in the treatment of breast cancer in women in the 1970s and showed effectiveness similar to that of other AAS.[1][2][4] The drug is the 11-dehydrogenated analogue and a metabolite of fluoxymesterone.[1][2][3][5]
