doping program that sport has ever seen." In response to Armstrong's argument that the eight-year statute of limitations for doping offenses had long since expired, USADA replied that the statute of limitations for doping offenses did not apply because of Armstrong's "fraudulent concealment" of his doping. Longstanding precedent in U.S. law holds that the statute of limitations does not apply in cases of fraudulent conduct by a defendant. Based on evidence received during the Armstrong investigation and its prosecutions, USADA forwarded its "reasoned decision" document and supporting information to the Union Cycliste International, the World Anti-Doping Agency, and the World Triathlon Corporation. USADA claimed that: BALCO investigation The Bay Area Laboratory Co-operative (BALCO) was a San Francisco Bay Area business that supplied anabolic steroids to professional athletes. BALCO was founded by Victor Conte, who sourced the drugs from Illinois chemist Patrick Arnold and distributed them with the help of personal trainer Greg Anderson. Together, they sold substances like erythropoietin and human growth hormone undetected from 1988 until 2002, when the official federal investigation of BALCO began. In the summer of 2003, USADA investigators received a syringe with trace amounts of a mysterious substance and launched their own investigation. The syringe went to Don Catlin, MD, the founder and then-director of the UCLA Olympic Analytical Laboratory, who had developed a testing process for the substance, tetrahydrogestrinone (THG). He tested 550 existing samples from athletes, of which 20 proved to be positive for THG. A number of athletes, including Marion Jones, Kelli White, British sprinter Dwain Chambers, shot putter Kevin Toth, middle distance runner Regina Jacobs, and hammer throwers John McEwen and Melissa Price were subsequently incriminated in the investigation. TJ Dillashaw In April 2019, UFC bantamweight champion TJ Dillashaw voluntarily relinquished his title, after adverse findings in a USADA test before his fight with Henry Cejudo. The test showed that Dillashaw tested positive for EPO, which he admitted to using. Blood doping was not commonly tested for in the UFC by that point, making this a milestone case.
