Justin Gatlin
On July 29, 2006, Justin Gatlin announced to the media that he had tested positive for high levels of testosterone at the Kansas Relays. Justin Gatlin was facing a lifetime ban from track and field, because he had already tested positive for an amphetamine 2001 at the Junior Olympics. It was determined that the amphetamine came from a prescription he had been taking for years. Justin avoided the lifetime ban by cooperating with doping authorities. On December 31, 2007 it was announced that Gatlin would be banned from track for four years, which made him ineligible to compete in the 2008 Beijing Summer Olympics.
