Nisterime

Nisterime (), also known as 2α-chloro-4,5α-dihydrotestosterone 3-"O"-("p"-nitrophenyl)oxime or as 2α-chloro-5α-androstan-17β-ol-3-one 3-"O"-("p"-nitrophenyl)oxime, is a synthetic anabolic-androgenic steroid (AAS) and a derivative of dihydrotestosterone (DHT) that was never marketed. The C17α acetate ester of nisterime, nisterime acetate (ORF-9326), also exists and was developed as a postcoital contraceptive but was similarly never marketed.
