Allyltestosterone

Allyltestosterone, or 17α-allyltestosterone, also known as 17α-allylandrost-4-en-17β-ol-3-one, is a steroid derived from testosterone that was first synthesized in 1936 and was never marketed.[1][2] Along with propyltestosterone (topterone), it has been patented as a topical antiandrogen and hair growth inhibitor.[2][3] Allyltestosterone is the parent structure of two marketed 19-nortestosterone progestins, allylestrenol and altrenogest.[4] These progestins are unique among testosterone derivatives in that they appear to be associated with few or no androgenic effects.[5][6][7][8]
