Australian track star Peter Bol says he has been ”exonerated” after the investigation into samples from a failed drug test was finalised.

Bol took to social media on Tuesday to express his relief after Sport Integrity Australia announced the investigation into the B sample from his positive test to synthetic EPO — made public in January — was inconclusive.

The 29-year-old had a provisional suspension lifted earlier this year but his name is now fully cleared ahead of the world athletics championships later this month.

“I have been exonerated,” Bol said on Twitter. “It was a false positive like I said all along!”

“The news from Sport Integrity Australia today was a dream come true. No one should have to experience what I have gone through this year.”

Bol had always maintained his innocence after the shock result from a test taken in October. An initial analysis found the samples did not match and Sport Integrity said in a statement there were no definitive findings from the subsequent investigation which has now been concluded.

“The further analysis resulted in varying expert opinions as to the positive or negative reporting of the sample, and the A-sample was reported as negative,” the statement read.

“As a result, Sport Integrity Australia has taken the decision not to progress an anti-doping rule violation for this sample. The investigation into this sample is finalised.”

According to the statement WADA “will now undertake a review of current EPO processes. It is important to highlight that the analysis for synthetic EPO is a unique process which is different to how other prohibited substances are identified.”

Bol finished fourth in the 800m final at the Tokyo Olympics and won silver in the event at the 2022 Commonwealth Games.
