Heavyweight contender Dillian Whyte is no stranger to stirring up the pot.

According to Whyte, the sport of boxing has a real problem with fighters using performance enhancing drugs - and he believes there are many boxers who are "legally cheating" - and he believes WBO, IBO, WBA, IBF champion Anthony Joshua is among the culprits.

Joshua was scheduled to face Jarrell Miller on June 1 at Madison Square Garden in New York City.

But Miller was pulled from the fight after failing three pre-fight drug tests. The boxer came up positive for banned performance enhancers EPO, HGG and GW1516.

Whyte explained his description of how boxers are legally cheating. He believes there are fighters cutting corners by securing Therapeutic Use Exemptions (TUEs) to allow them to use banned substances legally.

“Look at it like this - there’s loads of fighters who are legally cheating," Whyte said to The Mirror.

“There are many fighters on TUEs - Therapeutic Use Exemptions - who are legally juicing, the doctors just give it to them saying they’ve got asthma, they’ve got ADHD or whatever, and they’re legally juicing.

“That’s the bigger question in sport that needs looking into and needs shining a lot on, it’s TUEs, because you’d be shocked to see how many fighters are on stuff.”

And he feels Miller's state of mind was to take as many performance enhancers as possible, to even up the odds with Joshua.

“I think he’s thinking ‘I’m fighting a juice man so I’m getting on the juice too’. He kept on going on about Joshua’s therapeutic use exemptions so he knows Joshua’s on the TUEs," Whyte said.

“He’s thinking ‘boy, I’m gonna make my own TUEs up!’ He knows Joshua’s on TUEs so he probably just got scared. It’s a big fight and he doesn’t want to get hurt, he probably just got scared and thought ’sh*t I’m going to get killed, I’d better do something drastic.’”

Whyte himself tasted a two year ban after failing a random drug test stimulant that was found in a supplement called Jack3D, which Whyte had bought over the counter from a nutritional supplement shop.
