Did HGH have anything to do with Brett Favre's retirement? The NFL currently has drug testing for steroids but not for human growth hormone (HGH).  Supposedly it is coming this season or next as a urine test.

Favre is 38 and remained a QB well past the time most are still in the game. He was able to run and throw with the best and last season was one of his best!

HGH helps older players deal with the tough game and with the wear and tear on their bodies.. It decreases the chance of broken bones, boosts immunity against getting sick and increases muscle mass.

Did Brett Favre look at MLB Pitcher Roger Clemons' troubles and decide it was better to be remembered for his 16 year career with the Green Bay Packers, winning 1 Super Bowl, 3 MVP awards, 9 Pro-Bowls and breaking all types of NFL records?

He is heavily involved in a lot of charity/social projects, a definite for NFL Hall of Fame and being retired would lead to a lot of endorsements and advertising money.

Who knows?
