Athletes’ samples to be re-tested for designer steroid

ATHLETICS’ world governing body is to re-test all urine samples submitted at this year’s World Championships.

The IAAF wants to check whether any athletes were using a previously undetectable designer steroid THG which is at the heart of a new US doping scandal.

The IAAF, which has around 400 samples in storage from the World Championships, said that anyone found to have tested positive for THG would face serious consequences.
