MANILA, Philippines – Ultimate Fighting Championship (UFC) welterweight champion Georges St-Pierre (GSP) welcomes stricter drug testing in the sport after being accused by an opponent that he took performance-enhancing drugs (PEDs).

St-Pierre was accused by top contender Nick Diaz of using “plenty of steroids” in the build-up to their UFC 158 clash, which St-Pierre won via a dominant unanimous decision.

After the event, St-Pierre adamantly denied taking PEDs and said he is open to stricter drug testing in mixed martial arts.

“Never took steroids in my life,” said St-Pierre, as quoted by MMA Fighting. “I’m for Olympic testing in my sport. I’m up to do the test, for the Olympic test. I have no problem with that.”

“I’m not a cheater, (I) never cheated in my sport,” he added.

St-Pierre said he is open to being tested any time. “No problem. I’m for the testing. I think it should be more regulated,” he added.

The Canadian mixed martial artist said he takes it as a compliment that Diaz believed he was in steroids.

“For someone to say to me I’m athletic, I take that as a compliment. For him, in his mind to say, ‘He needs to steroids, he’s very athletic,’” St-Pierre said.

“For me, it boost my confidence by saying that,” he added.

Aside from St-Pierre, UFC lightweight champion Benson “Smooth” Henderson has also advocated for stricter drug testing in MMA.
