Why dope testing is fair game for athletes
It's less than a week since Springbok utility back Aphiwe Dyantyi was found guilty of doping.
The 25-year-old tested positive for "multiple anabolic steroids and metabolites" and is facing a ban of up to four years.
Khalid Galant from Drug-Free Sport explains more about the process of dope testing and the regulations of the World Anti-Doping Code.
We tend not to use random testing because it's a waste of money.Khalid Galant, CEO - Drug-Free Sport
He explains the types of variables which lead them to test.

Testing has to be as unpredictable as possible from the athlete's perspective. They shouldn't be able to predict any particular testing pattern.Khalid Galant, CEO - Drug-Free Sport
Dr Ross Tucker explains more about the potential effects of the specific drugs found in Dyantyi's system.
The substances were methandienone, methyltestosterone and LGD4033, all 3 of which are in Class S1, and prohibited at all times.
