Ultimate Fighting Championship (UFC) Heavyweight Burgermeister Roy Nelson is fed up (no pun intended) with the amount of cheating in the sport of mixed martial arts (MMA), to the degree that he's now "jaded" and "hates the world."

But he's ready to put his money where his mouth is.

"Big Country," who fights Dave Herman at UFC 146 this Saturday night (May 26, 2012) in Las Vegas, Nevada, tells MMA Fighting he's ready to start his own battery of pre-fight drug tests under the guidelines of the World Anti-Doping Agency (WADA), even if he has to pay for it himself.

"The sport of MMA leaves a sour taste in your mouth. It pays to cheat. I used to be passive about people that cheat. I might have to do WADA. I may even have to pay myself for testing my next opponent. I mean I'll do the blood tests, the whole nine yards. Whoever fights me next will have to do random blood tests, and it can even come out of my pocket if the UFC doesn't want to pay for it. If they don't want to test, it just shows how corrupt this sport is."
