SIX amateur Queensland rugby league players will today be banned for two years for testing positive to an illegal stimulant.
The Australian Sports Anti-Doping Authority will name all six players, who tested positive to methylhexaneamine, an ingredient common in pre-workout supplements.
It's understood that ASADA has already notified the footballers and will use their cases as a warning to other semi-professional athletes.
Methylhexaneamine - also called DMAA, dimethylamylamine or 1,3-dimethylpentylamine - is banned by the World Anti-Doping Agency.
The stimulant is also listed on the Therapeutic Goods Administration's Poisons Standard, an indication of the possible damage it can do.
Earlier this year, a London coroner ruled that DMAA was "a factor" in the death of female marathon runner Claire Squires.
The Daily Telegraph can reveal that all the players failed tests in the second half of last year, including four players from a single match in Brisbane's second division competition.
It's understood that all tests were conducted randomly post-match as part of ASADA's normal practice at different levels of the sport.
The footballers to be banned today are:
* ONE Queensland Cup player, the tier below NRL and the equivalent of NSW Cup;
* FOUR players from the QRL's Brisbane second division; and
* A PLAYER from the Townsville and District competition.
There was a spike in positive tests for DMAA several years ago, when ASADA recorded more than a dozen positive tests in a month.
On its website, ASADA warns: "Athletes have been banned for using the following methylhexaneamine-containing supplements: Jack3d, White Lightning, Hemo Rage, OxyELITE Pro and Thermo Jet.
"Methylhexaneamine is classed as a stimulant on the World Anti-Doping Agency's Prohibited List and it is prohibited in-competition.
"Generally, stimulants act directly on the central nervous system to speed up parts of the brain and body. They can increase alertness and reduce fatigue."
DMAA was patented in 2005 by Illinois chemist Patrick Arnold, who is best known for creating the designer steroids at the heart of the BALCO scandal that landed Sydney Olympics sprint queen Marion Jones in prison.
Food Standards Australia issued a strong warning about use of the supplement last year: "DMAA acts as a stimulant and is used in pre-workout sports supplements and party pills to provide an adrenaline-like high. It has been linked with various adverse health effects including high blood pressure, headaches, vomiting, cerebral haemorrhage, stroke and death."
Rugby league is a signatory to the WADA code, meaning the six men will be banned as players, coaches or trainers for the next two years.
