Dihydrofluoxymesterone (developmental code name U-7265) 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 at least one clinical study in the 1970s and showed effectiveness similar to that of other AAS.[1][2] The drug is the 5α-reduced analogue and metabolite of fluoxymesterone.[1][2][3]
