UFC president Dana White has responded to Jake Paul's previous drug-test challenge by reiterating his own willingness to test despite branding the wager "not serious".
The promotion's president was accused of using cocaine by Paul who issued a wager that he would be get tested for steroids providing White is tested for use of the substance.
Terms also included an increase in UFC fighter pay and improvement in the healthcare that they receive as the pair continued their row.
White has dismissed the challenge once again as Paul "joking around" but is happy to hand over any drug records for his UFC fighters who are regularly tested.
"I wanted him to do this and you saw his response," White told TSN. "This guy isn't serious he is f****** joking around and whatever.
"I know I don't do cocaine... you want to test, let's test and then he comes back with 'oh that's a compliment I have been lying around eating' well whatever if you have been cheating USADA (US Anti-Doping Agency) will get you.
"You want to take a drug test? No he does not. So obviously he didn't accept my challenge and if you are somebody that is going to fight him in the future push for hardcore drug testing.
"Oh and by the way he came back and said he will do it if I test all of my fighters. How did the warlock not tee him up and let him know that we f****** test all of our fighters.
"Our fighters are tested frequently and through the toughest drug testing policy in all of sports."
White accused Paul of using steroids and called for him to get tested, something which the Youtube star quickly dismissed.
A leak confirmed Paul had passed his drug testing for the recent rematch with former UFC champion Tyron Woodley.
Paul has made an enemy of the company's president since he first began his boxing career and has begged him to release his stars to hold talks over potential boxing fights.

He has even called to fight the president himself naming him on a boxing 'bucket-list' as his trolling continues.
The YouTube star has even begun MMA training in anticipation of meeting a UFC fighter in the cage or even competing under the Bellator or PFL banner.
For now White and Paul's feud has been largely shelved but UFC legend Chael Sonnen believes the YouTube star has picked the correct enemy.
"Jake can't go wrong, he just can't go wrong," Sonnen said on his YouTube channel. "All you're looking for when you look for an enemy is you're looking for a partner, that's all you want.
"You come after a guy and act like you're trying to ruin his day, but all you're really hoping for is that you get a response that spills over until tomorrow.
"And as long as you've still got a feud going with one guy you can just ping that back-and-forth until the audience is done with it.
"And Jake found himself the greatest nemesis that anybody could ever have."
