Demonising Justin Gatlin
13th September 2015
The Australian Sports Anti-Doping Authority (ASADA) has today acknowledged the decision of the NSW Rugby League to impose a two year ban on athlete Evrett Vaurasi for the presence and use of prohibited substances. Mr Vaurasi provided a sample on 22 April 2017 during an in-competition test. The sample was analysed at the Australian Sports Drug Testing Laboratory, part of the National Measurement Institute, which detected the presence of Higenamine and 1,4-Dimethylpentylamine.
Higenamine is an ingredient in many supplements, and is banned at all times under the S3 class of Beta-2 Agonists on the World Anti-Doping Agency’s Prohibited List 2017. 1,4-Dimethylpentylamine is banned in-competition only under the S6 classification of Stimulants. The substance is similar in structure to 1,3-dimethylamylamine (DMAA), which can cause side effects including cerebral haemorrhage and heart attacks and has been linked to a number of deaths in Australia and overseas. Mr Vaurasi waived his right to a hearing and is ineligible to participate, as an athlete or support person, in any sports that have adopted a World Anti-Doping Code compliant anti-doping policy until 8 March 2020.
ASADA’s longstanding advice is that athletes can never be 100% certain that any supplement is free from prohibited substances. Due to poor regulation of the industry, supplements companies are not required to prove that their products are safe, effective or even accurately labelled.
ASADA has issued a number of warnings about Higenamine, DMAA and supplements more broadly, including advice that up to 1 in 5 Australian supplements contain prohibited substances, often not listed on labels. To reduce their risk of testing positive, ASADA recommends athletes consider not taking supplements at all, or if required, that they choose low-risk products which have been batch tested by an independent auditing company.
To assist athletes, ASADA has released a new mobile app ASADA Clean Sport, which lists every batch-tested supplement available for sale on Australian shelves. The app is free to download and is available on Android and Apple phones. Further information on the risk of supplements and ways for athletes to reduce that risk is available on the ASADA website: https://www.asada.gov.au/substances/supplements-sport
