Buccaneers running back Earnest Graham said on a radio show Tuesday that he believes 30 percent of the NFL's players are using human growth hormone. "They don't have a [drug] test for [HGH]. It wouldn't shock me if a ton ... I'd say a lot of NFL players are doing it," Graham said on 1010 WQYK-AM. "I would say, I've heard a lot of people, even in Hollywood the average person is [using] HGH. It's supposed to be this great thing. Especially in a sport like football. You know, I would assume that a lot of guys have access to it and are using it. I would assume so. I wouldn't doubt it, man, with what's at stake. Especially in this game, not having guaranteed contracts you know with so much riding on your performance, a game that tears your body down like that, I would assume that a lot of people are making that decision to use HGH. Especially if there's not a test for it. Because at some point you feel like you're not cheating, you're not doing anything wrong. I would say definitely. I would not be shocked." "I mean, you know, sometimes. It gets done by, you know, just knowing a guy. Seeing how it benefits another guy. That's how it ends up, you know. Most guys don't have access to it, don't know how to go about it, probably won't take the time to check on it. So usually another guy refers it, you know, to someone and that's how all that starts."
