What Substances Are Banned?
Per USADA: “As a signatory to the World Anti-Doping Code, USADA tests for substances and methods found on the World Anti-Doping Agency Prohibited List. It’s important that athletes are aware of the substances and methods on the Prohibited List, as an athlete is responsible for any prohibited substance found in their body, regardless of intent. It’s also important to understand that certain substances are prohibited at all times, while others are prohibited only during competition. In some cases, a substance is only prohibited in a certain sport.
