"You've got HGH, something that doesn't show up on a test, and you've got guys out there trying to provide for their families," Peterson told ESPN.com's Kevin Seifert on Friday. "They're going to try to get that edge, get that advantage, especially if they're not worried about trying to get caught. Yeah, it's being used."
Peterson admits he has heard the whispers. His 2,097-yard campaign was met with a fair amount of suspicion on Twitter, as lackeys (led by @HGHPeterson) badgered Peterson with questions about using performance-enhancing drugs to fuel his heroics.
Said Peterson: "(Testing) will bring a lot of people to light. It'll clear a lot of people, on the outside, their curiosity when it comes to different players. So I'm all-in for it. I don't worry about those types of supplements, using those, because I'm all natural."
