Former longtime UFC welterweight kingpin Georges St-Pierre dropped a shocking revelation yesterday as to what had an impact in him deciding to take a hiatus from the sport.

“Rush” told Canadian media outlet RDS.ca (translation via MMA Fighting) that despite consistently pushing for stricter drug testing, it fell on deaf ears and eventually left the major pay-per-view draw disillusioned.

"The only thing I want to say is, I wanted to do something to help those who are honest in the sport. Believe me or not, I never took drugs in my life. I'll take a lie detector test, I don't care. I'm for anti-doping tests. I think it's a big problem in the sport,” St-Pierre said.

"This is a relatively new sport. There's one organization that has a monopoly, so the fighters don't have much power. They can't really talk because if one says what he thinks, he will get punished.

"If we want the sport to be accepted worldwide, like baseball, hockey, football, soccer, I believe [drug testing] is the thing to do. I think it's just a matter of time before it happens, it's just that I tried to make it happen now.”

UFC CEO Lorenzo Fertitta said he was “extremely disappointed” by his star employees remarks, stating that he believes the UFC institutes some of the strictest drug testing in professional sports.

St-Pierre won a hotly-contested split decision over Johny Hendricks at UFC 167 in November, his 12 straight win and his ninth consecutive successful title defense.

Immediately afterwards, the French-Canadian superstar announced that he had to take a break from the sport since he was feeling burned out.

Less than a week later, he lived up to his word and vacated the welterweight title.

During the buildup for the fight with Hendricks, GSP announced he would utilize the labs at the Voluntary Anti-Doping Association.

Instead, Hendricks opted for drug testing with the World Anti-Doping Agency, and when neither side could reach a middle ground, no extracurricular drug testing took place.
