Nick Diaz: ‘Georges St-Pierre was on steroids when I fought him’

Nick Diaz has never had a problem speaking his mind. If anything, his refusal to play by the rules of others – from in-fight taunting to refusal to stop smoking marijuana to shocking quotes – has been a major part of his appeal.

At UFC 158, Diaz (26-9 MMA, 7-6 UFC) had the opportunity to face Georges St-Pierre ( for the welterweight championship. Diaz lost the bout by unanimous decision, but he hasn’t exactly moved on from the bout with the all-time great.

“I’m pretty convinced about everybody is on steroids,” Diaz said during an appearance on Chael Sonnen’s “You’re Welcome” podcast. “I mean everybody. Me and my brother, I don’t think (Frankie Edgar) is on steroids, but a lot of these guys, they’re on steroids. That stuff messes with chemicals in your head. I’m just talking (expletive) on everybody right now cause as far as I’m concerned, everybody’s on steroids.”

Wil Diaz’s most recent opponent, Anderson Silva, actually did test positive for steroids after picking up a unanimous decision win, it was “GSP” he singled out.

“Georges St-Pierre was on steroids when I fought him.”

Diaz explained issues he had with the drug testing for the bout, which took place March 2013 in St-Pierre’s home city of Montreal, including the procedures used to collect urine for the tests.

Interestingly, Diaz also referenced his own clean tests for the bout as proof that things were not on the level.

“They didn’t test us because I would have tested positive for sure,” Diaz said. “I thought it was my last fight ever. What do I care? It was almost asking too much to win and not give away that fine.”
