Asafa Powell

The Jamaican relay team that won Olympic gold in Beijing in 2008, including Powell, was disqualified after a retest of teammate Nesta Carter's sample came back positive for methylhexaneamine. Powell consequently lost his relay gold medal retrospectively.

During a training camp in Lignano Sabbiadoro, Powell, Sherone Simpson and their trainer Christopher Xuereb came under investigation in Italy following a search and the seizure of medicines and supplements. In September 2015, a judge in Udine closed the investigation at the prosecution's request.

Powell and Sherone Simpson reached an out-of-court settlement with Dynamic Life Nutrition LLC, the company that sold the Epiphany D1 supplement. They had brought an action seeking 8 million dollars after independent testing identified ingredients not disclosed on the product label, including the oxilofrine underlying their anti-doping cases.

Protagonist is the complainant

The Jamaican disciplinary panel sanctioned Powell with eighteen months of ineligibility, retroactive to June 2013, following his positive oxilofrine test. Powell described the decision as unfair and announced an appeal.

CAS initially granted a stay allowing Powell to compete, then partially upheld his appeal and reduced the suspension from eighteen to six months. The proceedings established that the oxilofrine came from a contaminated version of a legal supplement, Epiphany D1; Powell was therefore able to resume competition immediately, having already served the suspension period.

Asafa Powell tested positive for the stimulant oxilofrine at the Jamaican championships/trials in June 2013. The result was made public in July, and subsequent analysis of the B sample confirmed the positive test. Powell maintained that he had never knowingly taken a prohibited substance and attributed the result to a dietary supplement supplied within his training environment.

Chinese brand Li-Ning suspended its agreement with Powell pending the outcome of investigations into his positive anti-doping test, stating that it would terminate the contract if the use of prohibited substances was definitively established.

Stephen Francis, coach at MVP Track Club, publicly demanded that Powell and Sherone Simpson sever ties with their agent Paul Doyle or leave the group. Francis accused the athletes of circumventing his programme's rules concerning external personnel and products used, against the backdrop of the positive test.
