Colorado Springs, Colo. – USADA announced today that Aaron Waldon, of Austin, Texas, an athlete in the sport of boxing, has accepted a three-year period of ineligibility for an anti-doping rule violation after testing positive for a prohibited substance.

Waldon, 24, tested positive for GW1516 sulfoxide, a metabolite of GW1516 (also known as GW501516, cardarine and endurobol) as the result of a urine sample collected at the 2024 USA Boxing National Championships on December 21, 2024. GW1516 and its metabolites are Prohibited Substances in the class of Hormone and Metabolic Modulators. They are prohibited at all times under the USADA Protocol for Olympic and Paralympic Movement Testing, the United States Olympic and Paralympic Committee National Anti-Doping Policy, and the World Boxing Anti-Doping Rules, all of which have adopted the World Anti-Doping Code and the World Anti-Doping Agency Prohibited List. USADA urgently advises athletes not to use this dangerous substance, and WADA has also issued a safety warning about GW1516.

Under Article 10.8.1 of the Code, an athlete who faces an anti-doping rule violation that carries a period of ineligibility of four or more years may receive a one-year sanction reduction if the athlete admits the violation and accepts the asserted sanction within 20 days of notification of the alleged anti-doping rule violation charge. Per the rule, Waldon qualified for a one-year reduction to the otherwise applicable four-year period of ineligibility.

Waldon’s three-year period of ineligibility began on January 9, 2025, the date his provisional suspension was imposed. In addition, Waldon has been disqualified from all competitive results obtained on and subsequent to December 21, 2024, the date his positive sample was collected, including forfeiture of any medals, points and prizes.
