Mestanolone

Mestanolone is an orally bioavailable androgenic steroid that is highly androgenic while only slightly anabolic. It is incapable of aromatization and is not an agonist of the progesterone receptor. 17alpha-methyl-5alpha-androstan-3beta,16beta,17beta-triol is a very useful screening target for the doping test of MTS and Mestanolone in racehorses.
