7alpha,11beta-Dimethyl-19-nortestosterone, made by 1,6-methyl addition to 17beta-acetoxy-11beta-methylestra-4,6-dien-3-one, was a highly potent and selective androgen response modulator, with enhanced androgen receptor binding, androgenic activity and anabolic:androgenic ratio over its two monomethyl homologs.
