USADA announced today that TJ Dillashaw, of Yorba Linda, Calif., has accepted a two-year sanction for a violation of the UFC® Anti-Doping Policy after testing positive for a prohibited substance.
Dillashaw, 33, tested positive for recombinant human erythropoietin (rHuEPO) as the result of an in-competition urine sample he provided on January 18, 2019. rHuEPO is a synthetic hormone used to stimulate the body’s production of red blood cells, thereby increasing oxygen transport and aerobic power, and is a prohibited substance in the class of Peptide Hormones, Growth Factors, Related Substances, and Mimetics under the UFC Anti-Doping Policy, which has adopted the World Anti-Doping Agency Prohibited List.
