Powerlifter receives sanction

  • Doping Violation Update

The Australian Sports Anti-Doping Authority (ASADA) today acknowledged the decision of Powerlifting Australia (PA) to impose a four-year ban on athlete David Johnston for the presence and use of prohibited substances.

Mr Johnston returned an Adverse Analytical Finding from an in-competition doping control test on 3 February 2018.

His sample was analysed at the Australian Sports Drug Testing Laboratory, part of the National Measurement Institute, which detected the presence of Prohibited Substances Ostarine and its metabolite O-Dephenyl Ostarine.

  • It was determined that on or before 3 February 2018, Mr Johnston used a Prohibited Substance Ostarine.
  • Ostarine is prohibited at all times under the S1 Anabolic Agent category of the WADA Prohibited List.

Ostarine is a Selective Androgen Receptor Modulator (SARM) that is not approved for human use or consumption in Australia. SARMs pose serious health concerns, including increased risk of heart attack, stroke and life-threatening liver toxicity.

Sport Integrity Australia is committed to protecting the right of clean athletes to fair competition.
