List of androgens and anabolic steroids

The major classes of testosterone derivatives include the following (as well as combinations thereof): The last group consists of progestins with mostly only very weak androgenic/anabolic activity.

The 17α-ethenylated (vinylated) testosterone derivative norvinisterone (vinylnortestosterone) is much more potent as an AAS than the 17α-ethynylated testosterone derivatives and is intermediate in potency between the 17α-ethynylated progestins and conventional AAS, with approximately one-third and one-fifth of the respective androgenic and anabolic activity of nandrolone in animal bioassays.

[2] 17α-Ethynylated testosterone derivatives are potent progestins with only very weak androgenic/anabolic activity and are used as oral contraceptives or for the treatment of gynecological conditions in women.

However, these progestins are testosterone derivatives and do have significant androgenic/anabolic activity, sometimes producing acne and other mild androgenic effects in women.

Conversely, in men, these drugs may actually have functional antiandrogen effects due to their potent progestogenic and hence antigonadotropic activity and capacity to suppress gonadal testosterone production.
