The U.S. Anti-Doping Agency announced Friday American cyclist Duane Dickey of Cokato, Minnesota, has accepted a lifetime suspension after a second anti-doping rule violation based on his use and possession of synthetic erythropoietin (EPO) as well as his refusal to submit to sample collection.

EPO, used to stimulate red blood cell production is among a class of Peptide Hormones, Growth Factors and Related Substances under the World Anti-Doping Code (“Code”) and the World Anti-Doping Agency Prohibited List.  Dickey also was charged with a violation of the Code for refusing to provide a sample when notified. The 41-year-old Dickey was alleged to have declined to cooperate with USADA out-of-competition testing on May 11, 2010.

Dickey’s lifetime period of ineligibility began on September 1, 2010, the day he accepted the sanction. Additionally, Dickey is disqualified from all competitive results achieved on and subsequent to April 2, 2007, the date he first committed the anti-doping rule violations, including forfeiture of any medals, points and prizes.

Dickey had previously received a one-year suspension in 2002 after testing positive for the prohibited substances phentermine, boldenone and nandrolone in a sample taken from him at the 2001 Tour of Guatemala.
