Methandrostenolone (trade names Averbol, Dianabol, Danabol), also known as metandienone (INN), methandienone, or informally as dianabol, is an orally-effective anabolic steroid originally developed in Germany and released in the US in the early 1960s by Ciba Specialty Chemicals. Methandrostenolone is a controlled substance in the United States and Western Europe and remains popular among bodybuilders. An injectable form is sold online from United States based companies. Methandrostenolone is readily available without a prescription in countries such as Mexico (under the trade name Reforvit-b), and is also being manufactured in Asia and many East European countries.
