The Beast Incarnate Brock Lesnar went into UFC 200 after nearly five years out of the octagon and beat a heavyweight contender pretty cleanly. Of course some people believe Lesnar was on something to get in the shape he was in for the fight and many believed he was somehow exempt from drug testing. Reports have surfaced that Lesnar was drug tested mightily during the run-up to his fight with Mark Hunt. Moreso, Lesnar is technically under some kind of UFC contract and will be subject to random drug tests by the United Stated Anti-Doping Agency.
Last time Brock was in the UFC they were not under the watch of the USADA so his return has been made under much more stringent drug screenings until Lesnar informs them that he is retiring from the sport. At that point if he were to retire, Lesnar would have to inform the USADA that he was coming out of retirement at least four months in advance and put under USADA drug testing. Of course, retirement doesn’t look to be in the cards at this time with the word going around that Brock is looking to get another fight later this year or possibly early 2017.
