methenolone

**Methenolone** is a synthetic androgen and anabolic steroid (AAS) used primarily in the form of esters (metenolone acetate and metenolone enanthate) for the treatment of anemia due to bone marrow failure and conditions involving muscle wasting. The drug acts as an agonist of the androgen receptor, the biological target of androgens like testosterone and dihydrotestosterone (DHT), exhibiting moderate anabolic and weak androgenic effects. Methenolone itself is not commonly used therapeutically, as only its esters are marketed clinically. It has no estrogenic effects or risk of liver toxicity, and side effects primarily involve masculinization. Methenolone was developed in the late 1950s, mainly by Schering, and is mostly discontinued today, with most medical use now being in the form of its esters[3][2].
