ethylestrenol

Ethylestrenol is a synthetic androgen and anabolic steroid (AAS) that was formerly used in humans to promote weight gain and treat conditions such as anemia and osteoporosis, but has since been discontinued for human use. It remains available for veterinary purposes in some countries. The drug acts primarily as an agonist of the androgen receptor, exhibiting strong anabolic effects relative to its weak androgenic activity, and also possesses significant progestogenic properties. Ethylestrenol is a 17α‐ethylated derivative of nandrolone and functions as a prodrug of norethandrolone. Its mechanism involves binding to the androgen receptor, modulating gene expression related to cellular proliferation and differentiation. Side effects include masculinization symptoms and risk of liver toxicity due to its 17α‐alkylation[3][5][6].
