Ethylestrenol (brand names Maxibolin, Orabolin), also known as 17α-ethylestr-4-en-17β-ol, is an anabolic steroid with some progestogenic activity, and little androgenic activity. It is a nandrolone derivative and lacks the 3-keto functional group. It was approved in 1964 for testosterone deficiency in male patients.
