Peyton Manning has been listed in a new Al Jazeera report as one of several prominent professional athletes who were supplied illegal performance-enhancing drugs from a pharmacist who once worked at an Indiana-based pharmacy.

Manning was reportedly given a supply of human growth hormone in 2011 while he was recovering from his 2011 neck surgery from a pharmacist then employed at the anti-aging Guyer Institute in Indiana. The report cites the pharmacist, Charlie Sly, who allegedly spoke to an undercover reporter working for the network.

In the report, titled "The Dark Side," Al Jazeera says in an article shared in advance with The Huffington Post that steroids and other drugs were shipped to the home address of Manning in 2011 in the name of his wife, Ashley Manning.

Sly also accused Manning and his wife in the undercover video of going to the clinic after its normal business hours for intravenous treatments.

Manning strongly denied the claims to ESPN's Chris Mortensen: "The allegation that I would do something like that is complete garbage and is totally made up. It never happened. Never. I really can't believe somebody would put something like this on the air. Whoever said this is making stuff up."

He went on to say that, "Yes, I have been a patient under Dr. Guyer. I have had nutrient therapy, oxygen therapy and other treatments that are holistic in nature but never HGH. My wife (Ashley) has never provided any medication for me to take. Ashley and I never attended the clinic together after hours. There were times when I went in the morning and there were times when I went after practice so this thing about `after hours' is so misleading because it may have been 5:15 pm because their office closed at 5."
