Is given an early reinstatement by the International Association of Athletics Federations (IAAF) the following year but warned a second violation would lead to a life ban.
* Tests positive for male sex hormone testosterone and its precursors at Kansas Relays in April 2006. Details of test do not emerge until Gatlin issues a statement on July 29, 2006.
Denies any wrongdoing and his coach claimed the positive test was the result of massage cream containing testosterone being rubbed into his buttocks.

Ban was reduced to four years by an arbitration panel in December, 2007.
* Court of Arbitration for Sport (CAS) rejects further appeal in June 2008.
* Returns to action in July 2010 after suspension ends.
