“It stings me, whoever this guy is, to insinuate that I cut corners, I broke NFL rules in order to get healthy. It’s a joke. It’s a freaking joke,” Manning said, reiterating that he did not use HGH.

Sly told ESPN’s Chris Mortensen that he isn’t a pharmacist and wasn’t at the Guyer Institute in 2011, as Al Jazeera claimed. State licensing records indicate that a Charles David Sly was licensed as a pharmacy intern in Indiana from April 2010 to May 2013. His license expired May 1, 2013.

Sly also said he recanted his story to Al Jazeera when he realized that it had used information he had “made up” to British hurdler Liam Collins, the undercover reporter who Sly said was trying to get into the supplementation business.

“When I was there, I had never seen the Mannings ever. They were not even living there at that time,” Sly said. “Someone who worked there said they had been there before. That was the extent of any knowledge I had. I feel badly. I never saw any files. This is just amazing that it reached this point.”
