Report: NFL, NFLPA to use former players to track HGH effects

A day after the NFL Players Association "tentatively agreed" with the NFL on in-season HGH testing, reports that dozens of former players will be administered human growth hormone as the league and the players union try to determine the impact of usage on players' HGH levels.

The tentative plan is for roughly 100 former players to participate in the study, with two-thirds receiving HGH and the other third receiving a placebo. Their HGH levels will be measured before and after the trial.

It's part of the scientific design of the population study that will include blood draws from all current players to determine the so-called decision limit -- i.e. the highest HGH level a player can have without facing discipline under the new performance-enhancing drug policy that is still being finalized, the people said.

It remains unclear if the former players targeted to be HGH guinea pigs have agreed to participate in the study, when the HGH would be administered, or how the HGH would be obtained.

Vikings players were notified of the plan Wednesday during a visit from the NFLPA, according to the report.

Meanwhile, Minnesota's best player, running back Adrian Peterson, has said recently that he welcomes HGH testing. There had been some not-so-quiet speculation that Peterson may have used human growth hormone to recover from a Dec. 2011 ACL injury after he returned nine months later and rushed for 2,097 yards, nine fewer than the all-time single-season record held by Eric Dickerson.

"Seriously -- especially with the amount of work I put in," Peterson said. "Guys say that to me, or if I hear someone saying that -- it makes me feel good. When you know you don't do it, and someone's saying you do, you're like, 'Wow. They think I'm on HGH? I'm doing that good? Well, hoo! Thank you, Jesus!' It's a compliment. I don't get mad about it at all."
