New steroid shows up in US athlete test samples

AMERICAN anti-doping chiefs revealed last night that a new anabolic steroid, which up until now has escaped all known doping controls, has been found in the test samples of several American athletes.

The United States Anti-Doping Agency, which has refused to name the athletes concerned, named the product Tetrahydrogestrinon (THG) a synthetic anabolic steroid.

It was found during the analysis of the contents of a syringe that was handed in, under anonymity, by a top athletics coach at the start of this summer, the USADA said.
