Former Olympic champion swimmer Ian Thorpe has submitted his final evidence to the Australian Sports Anti-Doping Authority in a bid to clear his name.
ASADA confirmed that Thorpe had offered evidence and records which he hoped would explain why he returned abnormal levels to two banned substances in a urine sample he gave in May 2006.
The 24 year old, who is a fivwe time Olympic gold medallist, has claimed his innocence since news of his case emerged at the world championships at Melbourne in March.
"ASADA can confirm on Wednesday, Aug. 16 it received the full and final submissions from Ian Thorpe into the matter of his unusual testosterone, epitestosterone and luteinizing hormone levels," the agency said.
"This material will now be examined by ASADA and a determination made as to the way forward.
"For operating reasons ASADA cannot go into any more detail."
Thorpe retired from competitive swimming in November 2006, several months before reports of his test results were printed in the French newspaper L'Equipe.
ASADA reportedly picked up the irregularity on Thorpe's sample but, in another test, found the increased levels to be naturally occurring and dismissed the case.
