USADA announced today that an independent arbitrator has rendered a decision in the case of weightlifting athlete Nicholas Dondzila of Saint Louis, Mo. After an evidentiary hearing on April 22, 2025, the arbitrator determined that Dondzila, 32, will receive a four-year sanction after testing positive for a prohibited substance and admitting to the possession of a prohibited substance. Dondzila tested positive for ostarine as a result of an in-competition urine sample collected at the North American Open Series 1 & National University Championships weightlifting event on March 1, 2024.
Ostarine is a non–Specified Substance in the class of Anabolic Agents and is prohibited at all times under the USADA Protocol for Olympic and Paralympic Movement Testing, the United States Olympic and Paralympic Committee National Anti-Doping Policies, and the International Weightlifting Federation Anti-Doping Rules, all of which have adopted the World Anti-Doping Code (the Code) and the World Anti-Doping Agency Prohibited List.
Dondzila’s four-year period of ineligibility began on March 20, 2024, the date he was provisionally suspended. In addition, Dondzila has been disqualified from any competitive results on and after March 1, 2024, the date of his positive test, including forfeiture of any medals, points, and prizes.
