Pettigrew admits to performance enhancing drugsOlympic 4x400m relay gold medalist, Antonio Pettigrew, recently admitted to using performance enhancing drugs.

Pettigrew is presently an assistant track coach at the University of North Carolina. He never tested positive during a track career that also earned him World Championship gold over 400m in 1991 and world relay gold in 1997, 1999, and 2001.

During three hours of testimony for the prosecution, Heredia recalled one instance when Graham asked him to send by overnight mail a cocktail of EPO, human growth hormone, and insulin for Marion Jones.
