AMIR KHAN said he is yet to be drug tested four weeks into his training camp to fight Kell Brook.
The welterweight rivals recently put pen to paper to at last confirm their bitter grudge match, set for February 19 in Manchester.
And Khan, currently training in Colorado, revealed the contract included drug testing - often done at random - but has not yet started the process.
He told: "I just sent a message to my wife the other day - I also copied my lawyer into it - saying, 'Can you please push whoever's like, Sky or Boxxer, Mr Shalom, Ben Shalom, saying the testing needs to be done'.
"I mean, I'm sat here, there's no testing being done, why? I'm waiting to be tested. I'm the one who had to push that.
"I said, 'Look, why's the tests not been done? It's a bit strange.
"Testing normally gets done when I normally work with VADA, or USADA it normally gets done like straight away.
"At a press conference they could turn up. But for some reason, I've been in camp for four weeks and there's no testing which has been done, which I find quite weird."

Sports lawyer Geoff Cunningham insisted that testing is contracted leading up to the fight, which is less than two months away.
Khan said: "Geoff Cunningham said to me, look it's in there.
"But I've not been tested yet and it's coming up to like my fifth week of training. And I'm like, 'What's going on?'
"We wanna be tested, I wanna be tested because it gives me that piece of mind knowing that it's a fair fight."
The 35-year-old pair have spent their entire careers linked to each other, and despite near-misses, a deal was never finalised.

Amir Khan ahead of his Kell Brook fight
It means their rivalry has continued to build and will now come to a climax when the first bell sounds next month.
But despite all the animosity over the years, Khan insisted the feud and eventual fight is not personal and will not let emotions deter his performance.
He said: "It's business, nothing personal with Kell.
"When you let things get to you personally, you lose that game plan and go in there with a lot of hatred and you want to hurt the person.
"I never want to make that mistake, I just want to go in there and box smart and do what I do best."
