Australian swimmer and alleged performance enhancing drug user Shayna Jack has slammed the world anti-doping system, labelling it "completely flawed."
Jack, 21, received a four-year ban in 2019 for testing positive to banned substance Ligandrol, a muscle growth agent.
When the sanction was handed down, Jack vowed to appeal and clear her name and has since been waiting for her case to be heard by the Court of Arbitration for Sport.
"There are many aspects of the anti-doping system that are seriously flawed but possibly the worst element is the presumption of guilt that one has to bear," Jack wrote on Instagram. "What sort of system infers that you are guilty of an alleged breach and the responsibility falls on you to prove your innocence?
"Nearly twelve months ago, my world was turned upside down despite a lifetime of competing clean and knowing that I had not used any prohibited substance. I was pitchforked into an unknown world of lawyers, politics and machinations that was completely foreign to me. The process has been extremely arduous and debilitating at times."
Despite the frustration, Jack remains committed to having the ban overturned and clearing her name. She is also eyeing a return to the Australian swimming team ahead of the Tokyo Olympics, which have been pushed back to 2021, due to COVID-19 restrictions.
"Now I have an opportunity to stand and fight for my career and reputation," Jack said. "I intend to win this fight and put myself back in the pool and reclaim my position as a member of the Australian swim team. Everyone knows what it is like to have something precious taken away from them and I am no different."
There is still no definitive date for Jack's appeal.
