Another American champion was hit with a shocking positive drug test Saturday

.......Olympic and world 100-meter champion Justin Gatlin. Gatlin said he has been informed that he tested positive for testosterone or other prohibited steroids _ the same violation that, only two days ago, threw Floyd Landis' victory in the Tour de France into question.

He said he will cooperate with USADA "and hope that when all the facts are revealed it will be determined that I have done nothing wrong."

"I cannot account for these results, because I have never knowingly used any banned substance or authorized anyone else to administer such a substance to me," Gatlin said. "In the course of my entire professional career, I have been tested more than 100 times. ... All of the tests this season, including the out-of-competition and in- competition tests conducted just before and after the race in Kansas, were negative."

Everyone has testosterone. Everyone. Some more some less.

The testing reveals above normal testosterone.

Whatever normal is.
