Methenolone structure

Side effects of metenolone esters include symptoms of masculinization like acne , increased hair growth , voice changes , and increased sexual desire . [5] Metenolone esters are synthetic androgens and anabolic steroids and hence are agonists of the androgen receptor (AR), the biological target of androgens like testosterone and dihydrotestosterone (DHT). [5] [7] They have moderate anabolic effects and weak androgenic effects, as well as no estrogenic effects or risk of liver damage . [5] [7] Metenolone esters are androgen esters and prodrugs of metenolone in the body. [5]
