USADA Investigates Athletes For Steroid Use

COLORADO SPRINGS, CO - OCTOBER 17: The entrance to the U.S. Anti-Doping Agency (USADA) is shown October 17, 2003 in Colorado Springs, Colorado. The USADA said today that it had uncovered a doping "conspiracy" involving tetrahydrogestrinone, a designer steroid known as THG, previously undetectable and allegedly used by several track and field athletes. Athletes testing positive for THG face two-year suspensions, disqualifying them from the 2004 Olympics. Reports say that the USADA investigation began in June and has expanded to other U.S. professional sports. (Photo by Tom Cooper/Getty Images)
