Georges St. Pierre was recently down in Brazil and spoke to the media about all manner of subjects. The former UFC welterweight champion says he feels healthier than he has in years without the stress of competition, adding that he still trains every day and has actually put on muscle mass since taking a break from the sport.

He also was asked about drug testing in the sport of mixed martial arts and expanded on his position:

I came out publicly about the performance enhancing drugs. I didn't do that to shoot the UFC or attack an individual. I believe if you attack an individual, twenty other will come. I didn't want to attack the UFC, I've always been the guy that want to defend the sport, but it's a new sport and I believe they should do the guideline and there should be more testing because it's a big problem. And I'm glad they ban the TRT because that was a big problem but they still have a lot of other things to do because it's a big problem in the sport. I didn't do that to blame the UFC. I did that to change the system. It's the system I want to attack, not the organization or the individual. It's the system of the sport itself. The UFC is the organization, it's not the sport. …. I believe what they should do is make it a random test. Especially for title fight or for any fight. Random test for carbon isotope. it's one of the newer tests they should think about doing. Putting a plan or something to take care of the problem.

Carbon Isotope Ratio (CIR) testing is the testing done to determine of the testosterone in an athlete's sample is natural or synthetic. It is one of the key tests in detecting PED use in athletes at the current time.
