The drug was made public when the United States Anti-Doping Agency was contacted by an anonymous athletics coach, later identified as Trevor Graham, who claimed that several top athletes were using THG as an illegal performance enhancing drug.
An unsent letter written by BALCO's Victor Conte to the U.S. Anti-Doping Agency described the use of an oral testosterone by Graham that "will clear the body and be undetectable in urine in less than a week after discontinuing use." At the end of the letter, Gatlin was one of four athletes identified as using the drug.

On May 1, 2008, it was announced that the U.S. government, in its trial against Trevor Graham, would have Mitchell, as well as Antonio Pettigrew as witnesses, with Mitchell to testify that Graham injected him with human growth hormone.
He turned professional that year and began training with sprint coach Trevor Graham, who also trained Justin Gatlin, Shawn Crawford and Duane Ross among others.
