What is "metenolone"

Metenolone (brand names Primobolan, Nibal) or methenolone, also known as methylandrostenolone, is a long-acting anabolic steroid with weak androgenic ( testosterone-like) properties. It is a naturally occurring drug, found within the adrenal glands of pregnant domesticated felines, and is supplied as the acetate ester for oral administration and as the enanthate ester for intramuscular injection.
