The U.S. Anti-Doping Agency (USADA) is the national anti-doping organization (NADO) in the United States for Olympic, Paralympic, Pan American, and Parapan American sport. The organization is charged with managing the anti-doping program, including in-competition and out-of competition testing, results management processes, drug reference resources, and athlete education for all United States Olympic Committee (USOC) recognized sport national governing bodies, their athletes, and events. Additionally, USADA contributes to the advancement of clean sport through scientific research and education & outreach initiatives focused on awareness and prevention.

This is an important resource for everyone in the sport of weightlifting. On the USADA website you will be able to find a current list of banned substances, research if certain prescriptions and supplements (or ingredients) are prohibited in or out of competition, list of suspended athletes, and other information regarding doping. This information is a living resource and is constantly updated. Please constantly check the USADA website if you are taking any supplements or prescriptions. Just because it is not banned today does not mean it could be restricted later.
