UFC heavyweight and light heavyweight champion Daniel Cormier showed off his spotless USADA testing record recently on Twitter.

Cormier, who won the heavyweight title vs. Stipe Miocic earlier this year, is looking to face Brock Lesnar in 2019 after the former champion is cleared to return.

According to his post, Cormier has been tested 67 times since 2001 by USADA, including 24 times since 2017.

“This is my @USADA testing history, from wrestling to MMA,” Cormier wrote. “67 tests!!!!!! 0 issues!!!!! Know what your taking. It’s your job!!!!! No excuses!!!! Fight clean!!! All the cheaters out there suck!”
