BMX rider/cyclist receives sanction

15 April 2019

The Australian Sports Anti-Doping Authority (ASADA) today acknowledged the decision of BMX Australia and Cycling Australia to impose a four-year ban on athlete Matthew Juster for the presence and use of prohibited substances.

Mr Juster returned an Adverse Analytical Finding from an Out-of-Competition Doping Control Test on 18 September 2017.

His sample was analysed at the Australian Sports Drug Testing Laboratory, part of the National Measurement Institute, which detected the presence of Exogenous Testosterone, Androsterone, Etiocholanolone and 5β-androstane-3α,17β-diol.

Mr Juster used a Prohibited Substance, namely Testosterone, on and/or before 18 September 2017.

Under category S1 of the World Anti-Doping Code Prohibited List 2017, Exogenous Testosterone, Androsterone, Etiocholanolone, and 5β-androstane-3α,17β-diol are anabolic agents prohibited both in-and out-of-competition.

Anabolic agents pose many threats to an athlete’s health and some side effects may include an increase in blood pressure and cholesterol levels which can lead to heart disease. Liver disease and infertility can also result from the use of these agents.

Mr Juster is ineligible to participate in any sports that have adopted a World Anti-Doping Code compliant anti-doping policy until 21 December 2021. He is also not permitted to compete in a non-Signatory professional league or Event organised by a non-Signatory event organisation.
