Simpson and former 100 meters 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 three-member Jamaica Anti Doping Disciplinary
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
One tested bottle, without an expiry date, showed the presence of
oxilofrine, while a bottle with an expiry date, did not, the report
from the Kentucky laboratory said.

A lawyer representing the Jamaican Anti-Doping Commission had
told the hearing on Tuesday there was no evidence to suggest
oxilofrine is contained in Epiphany D1.
Powell, who will have a similar hearing later this month, said
he had been unaware the two sprinters were taking the same
supplements, which were provided by Canadian physical therapist
"After we were notified of our positive test, we sat in my room
(in Lignano, Italy) and spoke," Powell said. "That's when I
found out we were taking the same things."
Simpson, testifying for a second day, told the panel she was
unaware of published advisories from the International
Association of Athletics Federations, the World Anti-Doping
Agency and other anti doping organizations against using
Simpson's hearing will resume on February 4.
Powell's is scheduled to begin on January 14.
