Metandienone 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. Metandienone is readily available without a prescription in countries such as Mexico (under the trade name Reforvit-b), and is also manufactured in Asia and many Eastern European countries.
