Following her successful appeal to the Court of Arbitration for Sport (CAS), Australian swimmer Shayna Jack has revealed how she believes the banned drug ligandrol has entered her system.
Jack returned a positive test for the banned substance in July last year, and was immediately withdrawn from the 2019 FINA World Championships.
She was given a four-year suspension at the end of her career immediately for the failed doping test.
Ligandrol, also known as LGD 4033, is a black market muscle builder that is known to improve your appearance without the unwanted side effects experienced with steroid use.
Jack has repeatedly pleaded his innocence, and the Swiss CAS decided to cut the 22-year-old girl’s ban in half on appeal, meaning she will be allowed to return to the pool next year.

While Jack remains unsure of how he ingested the substance, he suggested three possible sources to the CAS, as reported by The Daily Telegraph.
She told the court that her supplements may have been contaminated in the manufacturing process, while also suggesting that a blender used by her partner and brother may have been contaminated with ligandrol.
Finally, Jack told the court he may have been exposed to the substance while using a public pool or gym in Townsville or Cairns.

Although there was no evidence that any of these theories were correct, the CAS chose to cut its ban by two years, of which 17 months has already been introduced.
“The Sole Arbitrator in charge found this matter, on the balance of probabilities, that Shayna Jack did not inadvertently ingest ligand and considered that she had discharged her burden of proving that the anti-doping rule violation was not intentional,” he said CAS in its ruling.
“As a result, the Individual Arbitrator imposed a reduced period of ineligibility of two years, beginning with the date of her temporary suspension.”
If she qualifies for the Dolphins, the earliest Jack could represent Australia again at the world championships is in Japan in May 2022.
Cate Campbell, a gold medal winner at the Olympics, told the court she did not believe Jack would use performance enhancing drugs.
“In my years of knowing Shayna I have never seen any behavior that would suggest that she knowingly took a prohibited substance,” Campbell said, as reported by The Daily Telegraph.
“She has dealt with the highs and lows that sport offers with class and dignity and she has always behaved perfectly.”
