Norvinisterone (original) (raw)

Norvinisterone, sold under the brand names Neoprogestin and Nor-Progestelea, is a progestin and androgen/anabolic steroid (AAS) medication which was used in Europe but is now no longer marketed. It is taken by mouth. Norvinisterone is a progestin, or a synthetic progestogen, and hence is an agonist of the progesterone receptor, the biological target of progestogens like progesterone. It has androgenic activity. Norvinisterone was synthesized in 1953. It is no longer available.
