Metandienone

Metandienone, also known as methandienone or methandrostenolone and sold under the brand name Dianabol among others, is an androgen and anabolic steroid (AAS) medication. Metandienone was originally developed in 1955 by CIBA and marketed in Germany and the United States. As the CIBA product Dianabol, metandienone quickly became the first widely used AAS among professional and amateur athletes, and remains the most common orally active AAS for non-medical use. It is currently a controlled substance in the United States and United Kingdom and remains popular among bodybuilders. Metandienone is readily available without a prescription in certain countries such as Mexico, and is also manufactured in some Asian countries.
