LONDON, March 25 (UPI) -- Fears that use of the designer steroid THG could be widespread in British sport have been proved unfounded following the retesting of almost 1,000 samples.
UK Sport on Thursday announced that none of the 914 samples tested for THG (tetrahydrogestrinone) -- the supposedly undetectable steroid taken by banned British sprinter Dwain Chambers -- showed any traces of the drug.
John Scott, UK Sport's acting director of drug-free sport, said, "I am pleased to see that all samples tested for THG have come back negative."
"The furor that erupted when THG was first discovered meant it was important for us to conduct a thorough retrospective testing program to help ensure public confidence in the performance of our top competitors," he said.
The samples retested date to September and cover cycling, track and field, rugby league, rugby union, ice hockey, judo, triathlon, boxing, swimming and soccer.
