NINE Australian athletes - some believed to be AFL players - face two-year bans after testing positive to the same illegal drug in the biggest doping scandal to hit Australian sport.
Authorities last night would not rule out Commonwealth Games athletes as being among those who returned positive tests, but refused to release names after an anti-doping blitz of the nation's professional sporting bodies.
It is believed NRL and AFL players may have also been among those who tested positive in what could become Australia's biggest doping scandal.
The Advertiser can reveal the nine athletes tested positive for the banned chemical stimulant methylhexaneamine, or DMAA, used in body building and dietary supplements and increasingly used as a component of some party drugs.
Australian doping authorities said the results were alarming and signalled a "massive" spike in positive tests for DMAA, which was included on the global banned list at the end of 2009.

The testing period is believed to have covered this year's NRL and AFL grand finals and pre- and post-Commonwealth Games periods but not the 10 days of Games competition, which was covered by international anti-doping authorities.
The shock results last night prompted the Australian Sports Anti-Doping Authority to take the extraordinary measure of sending an urgent warning to all Australian athletes about inadvertent use of the substance.
SIMILAR clusters of positive tests to banned drugs are rare and only have come when testers identify a new product, such as the BALCO scandal that embroiled Sydney 2000 Olympic Games star US sprint queen Marion Jones.
There is concern that, with the London Olympics less than two years away and within the maximum ban time period, athletes may find themselves banned from competition by unknowingly taking the substance.
"It is a very large number in such a short period. That's why the warning has gone out," a source said.
DMAA is the same substance that cost Nigerian runner Osayomi Oludamola her Commonwealth Games gold medal - originally awarded under a cloud of controversy after Australian sprinter Sally Pearson was disqualified for jumping the gun in the 100m final.
ASADA chief executive Aurora Andruska last night confirmed nine athletes had tested positive for methylhexaneamine and were being investigated.
"This spike in positive test results is a reminder to all athletes to exercise utmost caution in checking the contents of supplements and other products they choose to use," she said.
"ASADA wants to get the warning out to the sporting community to be on the lookout for any supplement or product containing methylhexaneamine.
"Australian athletes must be very careful when using any supplement because, under the World Anti-Doping Code's policy of strict liability, athletes are responsible for any substance found in their body and we don't want to see Australians banned for methylhexaneamine."
Federal Sports Minister Mark Arbib urged Australian athletes to take extra precautions.
"The stimulant methylhexaneamine is appearing more and more in doping test results both here and overseas and has been linked to a number of popular supplements," he said.
"With the spike in the number of positive test results for methylhexaneamine in Australia, we are warning athletes to take extreme caution and double check the contents of any supplements and other products they use.
"The maximum sports ban for a first offence for methylhexaneamine is two years.
"I would hate to see an athlete receive a ban because they hadn't carefully checked the ingredients of a supplement."
The ASADA warning said that methylhexaneamine, also known as dimethylamylamine and dimethylpentylamine, was classed as an S6 stimulant on the World Anti-Doping Agency's Prohibited List for 2010 and is prohibited in-competition. In a rare official warning issued last night to athletes, ASADA said: "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.
"The Australian Sports Anti-Doping Authority is advising all Australian athletes subject to in-competition doping control to carefully consider their use of supplements and products containing methylhexaneamine."
ASADA is concerned many Australian athletes may be ingesting the chemical accidentally, unaware that otherwise harmless supplements may contain the substance, which often is not clearly identified in a product's list of ingredients.
