Conor McGregor savagely hits back at Joe Rogan following PED comments

McGregor hit back at Rogan in a tweet that appears to have been deleted.

Conor McGregor has hit back at Joe Rogan's suggestion that his urine would "burn a hole" through a drug testing cup. Rogan made the claim on an episode of his podcast in which he spoke to popular bodybuilder and performance-enhancing drug (PED) expert Derek, who runs the YouTube channel MorePlatesMoreDates. This was after Derek had exposed Brian Johnson a.k.a. The Liver King for his steroid use. Both Rogan and Derek agreed on the podcast that UFC fighter McGregor clearly "doesn’t pass the eye test” now that he has left the USADA testing pool. McGregor has previously suggested that athletes recovering from injuries should be allowed to use performance-enhancing drugs. “It seemed exactly like [McGregor was justifying PED use],” Rogan said about McGregor’s recent tweets, which he has since deleted. “Not only that. He’s taking his shirt off and posing constantly and he looks like his piss would melt that USADA cup,” he said. Now, McGregor has brutally hit back at Rogan. In a now-deleted tweet, the Notorious wrote: Joe looks like his piss melts his knickers, in the company that long and never took a fight hahaha @ufc oh tae kwon do competition, call the cops hahahahaah."
