Methenolone Acetate (Primobolan) CAS NO.434-05-9

Primobolan (methenolone acetate), all things being equal, is an excellent oral steroid drug. Unlike most other oral steroids, Primobolan is not 17-alkylated and does not have liver toxicity problems. Methenolone is perhaps only half as potent by the oral route as by injection, so dosages need to be high, at least 100 and preferably 200-300 mg per day, but if that can be afforded it is an excellent drug. It is unusual among oral steroids as being Class I, binding well to the androgen receptor.
