Mark Hunt has described the USADA drug testing of Brock Lesnar as a complete waste of time, but says: "I've been fighting against cheats my whole life".
Speaking with The Daily Telegraph from Las Vegas, where he faces Lesnar at UFC 200, Hunt said the WWE Superstar would already be enjoying the benefits of being "juiced to the gills".
In fact, the Sydney slugger joked that he would ignore the 120kg limit for UFC heavyweights in a bid to help "even things up" by fight night on July 9 (US time).
"They should have tested Brock before he signed the contract - not now," Hunt said. "It's a waste of time, testing him now.
"It doesn't matter if he's cleaned up. The benefits will already be there.
"They should have been testing him when he first started training for this fight ...
four months ago."
Asked if he was concerned about fighting an opponent he believed had been using PEDS, Hunt continued: "I've been fighting against cheats my whole life.
"Besides, what can I do about it?
"All I can do is punch his face. Punch his face several times.
"Actually, I'm not going to worry about making weight, even things up a bit. Right now, I'm weighing in at 'fat'.
"So I won't worry about a cut. Or maybe I should even start using myself.
"But really, I just want to get out there and punch Lesnar in the lips."
While Lesnar was initially granted a drug testing exemption for his UFC return, USADA has ramped up testing in recent weeks - visiting the American megastar five times in the space of a fortnight.
It comes after the UFC initially waived its usual policy that says athletes coming out of retirement give USADA four months' notice before fighting. Lesnar, 38, has not fought in the UFC since a loss to Alistair Overeem in 2011.
After the exemption was announced, Hunt told Fox Sports Australia: "I don't think that's fair. I think it's load of bulls**t, I think it's rubbish.
"I don't think anyone should be exempt from testing. If they're trying to clean the sport up - mixed martial arts - this is a bad way to do it. I don't care who you are. It's ridiculous.
"I don't think it's a great move. I think he's juiced to the gills - and I still think I'm going to knock him out."
