UFC superstar Nate Diaz is very vocal about PED use in mixed martial arts.

With the news of Jon Jones being flagged by the U.S. Anti-Doping Agency for a potential Anti-Doping violation, the issue of steroids was brought up with Diaz in a recent interview on “The Buzzer.”

“No one ever says what people get busted for when they test positive for steroids,” Diaz said. “But when Nick got busted, ‘what did Nick Diaz get suspended for? Cannabis.’ How come we all know that? How come it never goes away? How come it’s repeatedly talked about all the time?”

“But like when certain fighters start popping for steroids, they’re like ‘he tested positive for a banned substance. What banned substance? We don’t know.’”

“Silva, when he f—-ng (said) he (was) taking Viagra or some sh-t. So anytime we want to say that we didn’t do steroids, we say we’re popping Viagra? Get the f–k out, I ain’t buying it. You guys all did steroids, like why are they hiding it from people? To make the sport look better?”

“If anybody gets busted for something (and) no one’s saying what it is, it’s f—-ng steroids. And you’re all on steroids.”

Diaz went on to say that fighters continually blame not doing their research on what is on the banned list.

“Oh you accidentally took an Advil that had steroids in it? I’m not buying it motherf—-r. You did steroids, ok.”

Diaz showed his classic sense of humor and didn’t completely rule our steroid use in his future.

“You can test me every day of the year,” Diaz said proudly. “Piss loaded with cannabis, no steroids. You ain’t gonna catch no steroids in me for the rest of my life.”

“I can’t say that, maybe I’m 60 and don’t work no more, I’ll just take a steroid,” Diaz said laughing.

Nate Diaz is set to rematch Conor McGregor at UFC 202 on August 20 in Las Vegas, Nevada.
