A bombshell report released Saturday night placed Peyton Manning in the middle of a drug doping ring and could serve as a stain to the future Hall of Famer’s pristine legacy, even as he denies the allegations.

An Indianapolis anti-aging clinic shipped human growth hormone to the quarterback’s home in 2011 as he was recovering from neck surgery, an explosive Al Jazeera documentary will reveal Sunday, according to the Huffington Post.

A former pharmacist at the Guyer Clinic says the health center mailed HGH, which was banned as part of NFL’s 2011 collective bargaining agreement, to Manning’s house, addressed to his wife, Ashley, so the star’s name wouldn’t be implicated. Manning, who left Indianapolis for Denver the following year, had missed the entirety of the 2011 season after multiple neck surgeries, including a spinal fusion surgery.

“All the time we would be sending Ashley Manning drugs,” pharmacist Charlie Sly says in the video. “Like growth hormone, all the time, everywhere, Florida. And it would never be under Peyton’s name, it would always be under her name.”

Manning issued a strong denial Saturday night, saying: “The allegation that I would do something like that is complete garbage and is totally made up. It never happened. Never.”

He added, “I really can’t believe somebody would put something like this on the air. Whoever said this is making stuff up.”

Manning’s agent denied many of the report’s details to Al Jazeera — calling them “outrageous and wrong” — but did not deny that HGH was shipped to the Manning household.

“Any medical treatment received by Ashley is a private matter of hers, her doctor, and her family,” the agent said.

Sly says he supplied Manning with the drugs, but the legend is just one big-name athlete incriminated in “The Dark Side: Secrets of the Sports Dopers,” which will air at 9 p.m. Sunday. Sly also says he provided Delta-2 — a hormone supplement that is “steroidal in nature,” which Sly advertises as undetectable in drug testing — to Mike Tyson, Ryan Howard, Ryan Zimmerman, Julius Peppers and James Harrison, among others.

Sly also states he hooked up Green Bay linebacker Clay Matthews with Percocet, a prescription painkiller, before at least one NFL game.

In one scene of the documentary, according to Huffington Post, Taylor Teagarden, an eight-year MLB catcher who had a cup of coffee with the Mets in 2014, openly discusses his use of performance-enhancing drugs.

Sly, who was filmed undercover throughout by Liam Collins, a British hurdler, later backpedaled to Al Jazeera, saying his own statements in the documentary were “false and incorrect.”
