Olympic champion Ian Thorpe has given his final submission to the Australian Sports Anti-Doping Authority (ASADA) in an attempt to clear his name.
Thorpe said hearing about his test result was "gut-wrenching"
The Australian returned a drug test in May 2006 with abnormal levels of testosterone and leutenising hormone.
"This material will now be examined by us and a determination made as to the way forward," said an ASADA statement.
Thorpe, now retired, has always denied any wrongdoing since his abnormal test results were leaked last March.
"ASADA can confirm on Wednesday 16 August it received the full and final submissions from Ian Thorpe into the matter of his unusual testosterone, epitestosterone and luteinizing hormone levels," the statement read.
"For operating reasons, ASADA cannot go into any more detail."
ASADA has been under fire for the length of time it was taking over analysing Thorpe's test.
In April, swimming's governing body Fina asked the Court of Arbitration for Sport to rule on whether Thorpe's sample constitutes a doping violation.
Both testosterone and leutenising hormone are on the banned list but are naturally produced by the body.
Fina said it "considered the findings of this sample as an adverse analytical result".
It said it had lodged an appeal with the CAS "with the aim of clarifying the issues surrounding this case".
