Hunter is almost certainly on PEDs but congrats.
His perfomrance is so singular and rare in an era where PEDs are so common and where there is such great incentive to cheat (esp HS where there is no testing and a college scholarship for 250k is in the offing), that it is almost impossible to presume he isn't using EPo or test to help him. I know for a fact that even B level cross county kids use EPO to improve their times in regular communities, it would be very logical for Hunter to be using.
I strongly suspect that guys like Ryun, Elliott, Snell and other greats used testosterone (not illegal then and widely used in Europe since the 1920s by athletes, Paavo Nurmi used it and used by soldiers in WWII, Vietnam). The entire metaphor of Captain America is based on the discovery of synthetic testosterone. Our athletic, military and man culture has been defined by PEDs since WW 2.
Who?
Looks like it was made by a millennial in his basement
