TORONTO – Former UFC champion Georges St-Pierre still has no idea if he’ll fight again. But if he does, he said random drug testing must absolutely be involved.

“If I ever come back and fight again, (random drug testing) is mandatory,” St-Pierre told MMAjunkie at The Gentlemen’s Expo this past weekend in Toronto. “I’ll do it for myself and for my opponent. I will pay for it. I don’t mind. If the other guys in the sport don’t want to be tested, that’s fine. But for me and my opponent, it’s mandatory.”

St-Pierre’s (25-2 MMA, 19-2 UFC) stance against performance-enhancing drugs (PEDs) is nothing new. He was very outspoken about his desire for increased drug testing ahead of a UFC 167 showdown with Johny Hendricks in November 2013, though it didn’t go as smoothly as he hoped.

Ever since the 33-year-old announced he was vacating the UFC title and taking a hiatus from the sport, in part due to concerns over current drug testing, the UFC has stepped up its testing protocols in small increments.

The organization has footed the bill for several random drug tests this year. And beginning in 2015, the UFC apparently plans to make a multi-million dollar investment to launch a full-scale testing program for its entire roster.

St-Pierre said that’s a positive move, so long as the UFC partners with an able testing association.

“Hopefully it will be done by a competent and independent organization that has no interest in the money,” St-Pierre said. “We’ll see how it’s going to be done. Hopefully it will be handled well and be very professional. I just want it to be a clean, fair fight. You’re putting your life and well being on the line. I did it 24 times for the UFC, so it’s important to get it right.”

St-Pierre has been around long enough to know the sport’s issues behind the scenes. He knows that, regardless of the level of testing, it’ll be difficult to weed out every cheater. However, any step toward the betterment of the sport outweighs no steps at all, he said.

“The technology to use the drugs will always have an edge on the technology testing for the drugs; that’s how it is,” St-Pierre said. “If you do random testing, it will make things harder. We have a big problem with testosterone, synthetic drugs, EPO and growth hormone. People use that for recuperation. It’s a big problem in the sport. You cannot catch everybody, but at least if you make random drug testing, people will be on their guard.”

Considering such testing was essentially nonexistent when St-Pierre debuted with the UFC in 2004, he said he’s glad to see concrete steps. However, with his competitive career at or nearing its end, the former champ said he regrets he didn’t speak up earlier.

“My regret is I should have done it a long time ago, but I didn’t have – in the UFC, the problem is a lot of fighters don’t have the star power and the money,” St-Pierre said. “I used to be one of these guys. I started from the bottom, and I didn’t have enough money to say what I think about out loud. Now that I have the money, I can speak out. If I fight again, I can put my condition down (for random testing).”

Having just crossed the one-year anniversary of his last fight, St-Pierre said he’s still mulling the idea of a comeback. He was recently cleared to resume training after knee surgery, but said that clearance has no baring on whether he’ll continue to compete.

St-Pierre said he hasn’t been able to fully enjoy his layoff due to the rehabilitation requirements. Now that he’s 100 percent healthy, though, he can fully embrace life outside of competition. Once he does that, he’ll make a final decision about stepping back in the octagon.

“People always ask me if I’m going to come back, and I make an analogy,” St-Pierre said. “Bernard Hopkins said it best. They always asked him after his fight, ‘Hey, Bernard. Are you going to retire?’ And he would say, ‘You cannot ask a women who just gave birth and suffered for hours if she wants to have another kid after she just gave birth.’

“It’s the same thing. When you finish fighting, you don’t want to hear these things because of everything you’ve been through in the fight and the training camp. For me, I just finished my rehab, and I just started enjoying my time and my vacation now. I need time to know if I’m going to do this.”
