More than four days after a report alleging to link Broncos quarterback Peyton Manning and his wife, Ashley, to human growth hormone (HGH) was published, new details about the report's primary source and the doctor who treated Manning in 2011 have come to light.

In al-Jazeera's undercover investigation, " The Dark Side," Charles David Sly, a man labeled as a pharmacist, was filmed saying HGH was shipped from The Guyer Institute in Indianapolis to Ashley Manning "all the time, everywhere, Florida. And it would never be under Peyton's name. It would always be under her name. We were sending it everywhere. It would go to Florida."

Peyton Manning was a patient of Dr. Leonard Guyer while recovering from four neck surgeries in 2011. In a televised interview on ESPN Sunday, Manning said he received only holistic treatments from Guyer, adding that any treatment his wife received is "her business.

"I don't have a whole lot to add to what I said on Sunday," Manning said at the Broncos' facility Wednesday. "The report wasn't true Sunday, it's not true today and will never be true. I'm still angry about it."

Manning, upset his wife was drawn into the controversy, said he hasn't decided if he'll take legal action and doesn't want "to deal with it until after the season."

The connection to HGH is not new for Guyer. As noted by The Indianapolis Star, a 2007 federal indictment against Thomas Bader and College Pharmacy of Colorado Springs alleged Guyer received Chinese HGH that was not approved by the FDA from College Pharmacy "on or around Feb. 22, 2007."

Bader was found guilty in 2010 and sentenced to 40 months in prison for illegally importing human growth hormone from China and other charges related to his sale of HGH.
