According to a report from New York Times, which cited a document filed during a Sunday hearing before the Court of Arbitration for Sport (CAS).
Two of these substances, Hypoxen and the supplement L-carnitine, are not banned by the World Anti-Doping Agency (WADA), which regulates drug use in international sport.
Valieva declared both on a doping control form, according to a lawsuit allegedly filed by the World Anti-Doping Agency (WADA) in a case that arose after it emerged that Valieva had tested positive for a substance. banned in December.
The London-based Dossier Center, an investigative website run by an exiled Russian businessman, published part of the AMA’s legal request online and it was reviewed for CNN by Travis Tygart , head of the United States Anti-Doping Agency (USADA). The Dossier Center has not released the doping control form or test report presented in the case, and CNN has not reviewed them.
CNN has contacted CAS and the parties involved in Valieva’s arbitration hearing to confirm the validity of the legal petition published by the Dossier Center and has not yet received a response. CNN has also reached out to the WADA-accredited lab in Sweden that tested Valieva’s sample from December for comment. Tygart, who is not involved in the investigation of the Russian skater, called the application published by the Dossier Center “accurate and legitimate”.
The 15-year-old skater has been in the spotlight since it emerged days after the Olympics that she tested positive for the banned heart drug trimetazidine, which experts say can improve endurance. Valieva sought to blame the positive test on contamination from drugs taken by her grandfather, an IOC official familiar with the CAS hearing said on Tuesday.
The presence of additional substances raises further questions about the skater’s drug use, according to Tygart. USADA tried to ban Hypoxen in 2017 because of its performance-enhancing abilities, but that ban was not implemented, Tygart told CNN.
“It raises a whole host of questions that have yet to be answered and what appears to be a fairly deliberate attempt to use performance-enhancing substances,” Tygart said.
“The picture this paints is that you have a 15 year old teenager. Does she have the means, knowledge and financial resources to find and use two drugs, one of which is banned TMZ (Trimetazidine) and one other Hypoxene, [along with] L-carnitine (a supplement) – to increase endurance and reduce fatigue?” he said.
