USADA announced today that Chris Creveling, of Salt Lake City, Utah, an athlete in the sport of speed skating, has tested positive for a prohibited substance and accepted a four-year sanction for his violation.

Creveling, 30, tested positive for clomiphene as a result of an out-of-competition urine sample he provided on October 18, 2016. Clomiphene is a Specified Substance in the class of Hormone and Metabolic Modulators and is prohibited at all times under the USADA Protocol for Olympic and Paralympic Movement Testing, the United States Olympic Committee National Anti-Doping Policies, and the International Skating Union Anti-Doping Policy, all of which have adopted the World Anti-Doping Code and the World Anti-Doping Agency Prohibited List.

Creveling’s four-year period of ineligibility began on November 18, 2016, the date he accepted a provisional suspension. In addition, Creveling has been disqualified from all competitive results obtained on and subsequent to October 18, 2016, the date his positive sample was collected, including forfeiture of any medals, points and prizes.

In an effort to aid athletes, as well as all support team members such as parents and coaches, in understanding the rules applicable to them, USADA provides comprehensive instruction on its website on the testing process and prohibited substances, how to obtain permission to use a necessary medication, and the risks and dangers of taking supplements as well as performance-enhancing and recreational drugs. In addition, USADA manages a drug reference hotline, Drug Reference Online (www.GlobalDRO.com), conducts educational sessions with National Governing Bodies and their athletes, and proactively distributes a multitude of educational materials, such as the Prohibited List, easy-reference wallet cards, periodic newsletters, and protocol and policy reference documentation.

USADA is responsible for the testing and results management process for athletes in the U.S. Olympic and Paralympic Movement, and is equally dedicated to preserving the integrity of sport through research initiatives and educational programs.
