ASADA Warning - Methylhexaneamine (October 2010)

Australian athletes are being warned by the Australian Sports Anti-Doping Authority to carefully consider their use of supplements following nine positive Australian test results for the prohibited stimulant methylhexaneamine.

There has been increasing evidence that methylhexaneamine is present in supplements and other products and this spike in positive test results is a timely reminder to the sporting community to exercise the utmost caution in checking the contents of supplements and other products that athletes use.

Athletes need to be aware that, under the policy of strict liability, they are responsible for any substance found in their body. Athletes using supplements do so at their own risk and, because of supplement manufacturing processes can lead to their contents varying from batch to batch, ASADA cannot advise if supplements contain prohibited substances.

Further important information on methylhexaneamine and supplements can be found on the ASADA website – www.asada.gov.au – or by calling the ASADA Hotline on 13 000 ASADA (13 000 27232).
