Interesting story out linking a number of footballers and deer-antler extract. Ray Lewis is the poster-boy on this one, although he's denied being a user. The active ingreedient is a offshoot of HGH, so it sounds like something that would both be attractive to atheletes, especially when the "NFL said it is not detectable with the league's current testing methods."
Since Lewis is slated to retire after the Super Bowl, there's little the NFL can do if the story was true. Most punishments are suspensions, which would only have any weight if Lewis took some sort of coaching or front-office job.
The Tide players who are alleged to be on the stuff might be a different story.
Rhino horn's been long thought to be an aphrodesiac, but college football players shouldn't need any help on that front, especially their QB.
