Private investigators working for Peyton Manning visited the source of a report that he and other star athletes had obtained performance-enhancing drugs before the documentary aired late last year, according to a report from The Washington Post on Thursday.

In December, Al Jazeera reported that an intern at an Indianapolis anti-aging clinic was secretly recorded suggesting that Manning's wife received deliveries of human growth hormone in 2011. Manning, then with the Colts,Air Max 90 Essential White And Black Womens, was rehabbing from neck surgeries.
Manning's lawyers launched the private probe shortly after Al Jazeera started contacting athletes who would be named in documentary in December.

Fleisher did confirm to the Post that the Indianapolis anti-aging clinic shipped medication to Manning's wife. But, citing her right to privacy, he declined to say if it was human growth hormone.
They hired investigators to identify, locate and interrogate Sly and sent a lawyer to examine Peyton and Ashley's medical records at the Guyer Institute of Molecular Medicine in Indianapolis, according to Ari Fleisher, the former White House press secretary and crisis management consultant Manning hired.
Fleisher told the Post that Manning's investigative team didn't interfere with subsequent investigations nor did they remove any medical records or coerce Sly into recanting his statements.
