The World Anti-Doping Agency (WADA) website lists methylhexanamine as a specified stimulant which is banned in competition.
This means one that Carter’s case may be more likely to be accepted as a “credible, non-doping explanation”.
Since then he’s won two Olympic gold medals in 2008 and 2012, and three World Championship golds in 2011, 2013 and 2015.
This news is the latest development in an investigation of 454 samples from 2008.
Carter was also a member of the London Olympics 4×100 metre Jamaica relay team. He has not run this season, citing a foot injury, but is expected to race in the next few weeks before Jamaica’s Olympic trials, which start later this month.
If Carter is subjected to doping sanctions, it could mean Bolt stands to lose his relay gold. The drug has been recently used as an ingredient in dietary supplements after being initially sold as a nasal decongestant in the United States until 1983.
“What we want to do, and are trying to do, is target athletes who have positive results and stop them from competing in Rio”. The runner is one of 31 competitors that were originally deemed clean, but failed after a re-test of their sample from the 2008 Beijing Games.
In the past, when a single member of relay team has tested positive for a banned substance, the entire team has lost their medals.
Russian Federation has already said 14 of its athletes were among the positive tests from 2008.
