Tests show Simpson's supplement contained banned drug

KINGSTON, Jan 9 - The majority of tests conducted on a supplement suspended Jamaican sprinter Sherone Simpson was taking revealed a banned substance, the 2008 Olympic silver medallist's doping hearing was told on Wednesday.

Simpson and former 100 metres world record holder Asafa Powell, who also testified at Wednesday's hearing, returned adverse findings for the banned drug, oxilofrine, at June's Jamaican championships.

Both face two-year bans if found guilty of doping violations.

Two separate tests on a sealed bottle of "Epiphany D1", a supplement she was taking, showed the presence of banned drug oxilofrine, Professor Wayne McLaughlin of Caribbean Toxicology, a witness for Simpson, told the threemember Jamaica Anti Doping Disciplinary Panel.

McLaughlin noted, however, the drug was not listed on the label of ingredients of Epiphany D1.

But testing by HFL Sports Science-Informed Sports, showed conflicting results, according to documents submitted by Simpson's legal team.
