World record-setting swimmer Jessica Hardy has survived a doping suspension that prevented Hardy from competing in the 2008 Olympic Games to make a comeback to the London Olympics.

It was ruled by two panels that the positive test of Hardy was a result of her unknowingly ingesting a tainted supplement.

Hardy arrives in London as a contender for medals in the two freestyles as well as the 400-meter freestyle and 400 medley relays. Her family provided samples of supplements left over from the batch she used at the Olympic Trials to be tested by Anti-Doping Research Inc. and clenbuterol was found in an AdvoCare drink supplement.

Hardy recently was placed first in the women’s open 50 LC meter freestyle championship final during the 2012 TYR Fran Crippen Memorial Swim Meet of Championships at Marguerite Recreation Center in Mission Viejo on April 21.
