A - Z of THG

Tetrahydrogestrinone (THG) is the steroid at the centre of the new major athletics doping scandal. Health24 explains what the drug is.

It is believed that British sprinter Dwain Chambers and up to 20 American athletes tested positive for tetrahydrogestrinone (THG). The athletes who tested positive for THG include Olympic champions and world record holders. The International Association of Athletics Federations announced that it will re-test around 400 samples taken during the world athletics championships in Paris in August.

It is a new, specially designed anabolic steroid which has been tweaked by chemists to make it undetectable under normal testing.
