Bolandiol (INN, also known as 19-nor-4-androstenediol, estr-4-ene-3β,17β-diol, or 3β-dihydronandrolone) is an anabolic-androgenic steroid (AAS) that was never marketed.[1] However, a dipropionate ester derivative, bolandiol dipropionate, has been marketed.[1][2] Bolandiol and its dipropionate ester are unique among AASs in that they reportedly also possesses estrogenic and progestogenic activity.[3][4]

Bolandiol is on the World Anti-Doping Agency's list of prohibited substances,[5] and is therefore banned from use in most major sports. It is a potential metabolic precursor to nandrolone.[6] However, several clinical studies have concluded that bolandiol does not alter strength, body composition, or exercise performance.[7][8]
