http://en.wikipedia.org/wiki/1,3-dimethylamylamineIn 2009, the World Anti-Doping Agency added methylhexanamine to the 2010 prohibited list.[16]
Methylhexanamine was implicated as a stimulant used by five Jamaican athletes in 2009. JADCO, the Jamaican anti-doping panel, was initially unable to determine whether it was prohibited by the rules,[17] but subsequently decided to impose sanctions on some of the affected athletes on the grounds that the drug was similar in structure to the banned substance tuaminoheptane.[18]
During the 2010 Commonwealth Games, Nigerian athlete Damola Osayemi was stripped of her gold medal in the 100m after methylhexanamine was detected during drug testing.[19] Subsequently, another Nigerian athlete, Samuel Okon, who finished sixth in the 110m hurdles, also tested positive for the drug.[20]
In October 2010, two Portuguese cyclists - Rui Costa and his brother Mario - tested positive for the substance. The samples were taken during the Portuguese National Championships at the end of June.[21]
In October 2010, nine Australian athletes have been found by Australian Sports Anti-doping Authority to have tested positive for the substance. These players may include NRL and AFL players. [22]
In November 2010 two South African rugby union players, Chiliboy Ralepelle and Bjorn Basson, were found to have tested positive for the substance on their annual tour of the Northern Hemisphere, and were immediately sent home from the tour by the South African Rugby Union, although it is possible that the players may have ingested the substance inadvertently in the form of medication for flu symptoms.[23]
In 2010 Belgian National Amateur Masters Champion Rudy Taelman was suspended for one year for a positive test for methylhexanamine. He successfully defended himself from accusations of willful doping by proving that a supplement called "Crack" had caused the non-negative test. It should be noted that he was an active anti-doping advocate, and ironically the one to call for the doping controls to which he was submitted. [24]
In January 2011, the Greek basketball team Iraklis indefinitely suspended Matt Bouldin after he tested positive for methylhexanamine.[25]
