Who is Justin Gatlin

Justin Gatlin is an American sprinter.

On July 29, 2006 Justin Gatlin told the media that he had been informed by the USADA that he had given a positive doping test in April the same year. He did, however, claim his innocence in the matter: "I cannot account for these results, because I have never knowingly used any banned substance or authorized anyone to administer such a substance to me."

It is believed that the substance that Gatlin has tested positive for was "testosterone or its precursor." The failed test was revealed after a relay race on April 22, 2006 in Lawrence, Kansas. The "B" sample was confirmed as positive in July.
