KINGSTON (AFP) - Former 100m world record holder Asafa Powell told a Jamaican disciplinary hearing that he doubled the dosage of his supplements the morning of his positive drug test.
The 31-year-old Jamaican sprint star told the Jamaican Anti-doping Commission panel on Tuesday, Jan 14, 2014, that he did so on the advice of his newly-hired physical therapist Christopher Xuereb.
Powell, who tested positive for the banned stimulant oxilofrine at the Jamaican national championships last June, said Xuereb told him to take two capsules of Epiphany D1 each morning for the first week then double it for the second week. Powell claims Epiphany D1 was the source of the oxilofrine.
"I didn't remember to do that (double the dosage). Chris (Xuereb) came to my room the morning of the trials and said I must remember to take four," said Powell, who began his testimony on Tuesday morning.
The hearing in front of a three member panel is scheduled to last two days.
Powell said he started taking the supplements from Canadian physical therapist Xuereb about a month before the Jamaican championships, which were held from June 20 to June 23.
Powell also testified that he could not remember the names of the supplements he was taking at the time and he had not checked to see if Epiphany D1 was on the World Anti-doping Agency's list of banned products.
"I don't know the list, but I knew of the list," Powell said. "I know there is a list we are suppose to check."
Powell was also asked if he was aware of the risk in taking supplements. He said: "There are risks in everything." Powell also said he did not include Epiphany D1 on his doping control form.
Asked why he did not, Powell replied, "I could not remember after all the excitement at trials.
"All the supplements were new to me, so I could not remember all of them." Asked if he was surprised his former training partner Sherone Simpson gave a similar answer, Powell said, "No sir".
Three time Olympic medallist Simpson also tested positive for the same stimulant. Both sprinters have been banned from competing.
Power, who is one of Jamaica's greatest sprinters of all-time, set a world record in the 100m in 2008 with a time of 9.74 seconds.
