Report: Clemens Took Viagra to Help On-Field Performance?

Is there anything this guy wasn't taking?

No wonder he's so hard-headed?

He told little white lies ... and he took little blue pills.

Roger Clemens, whose claims he never took steroids are under federal investigation, has apparently discovered the benefits of another performance-enhancing drug sweeping the sports world - Viagra.

Clemens stashed the clearly marked, diamond-shaped pills in a GNC vitamin bottle in his locker at Yankee Stadium, according to a source familiar with the clubhouse, perhaps keeping the drug undercover to avoid the inevitable wisecracks about all the girlfriends he needed to please.

Clemens wasn't alone. The pitcher, who is believed to have scored the drug from a teammate, joined the burgeoning number of athletes who have turned Vitamin V and its over-the-counter substitutes into one of the hottest drugs in locker rooms.

The drug is so widely used for off-label purposes that it has drawn the attention of anti-doping officials and law-enforcement agencies in the United States and beyond.

"All my athletes took it," BALCO founder Victor Conte, whose acolytes included Jason Giambi, Barry Bonds and Marion Jones, said of an over-the-counter supplement he claimed mimicked the effects of Viagra.

"It's bigger than creatine. It's the biggest product in nutritional supplements."

Viagra, apparently, has its benefits outside the bedroom.

Helps build endurance, especially for athletes who compete at high altitudes.

Delivers oxygen, nutrients and performance-enhancing drugs to muscles more efficiently.

Counteracts the impotence that can be a side-effect of testosterone injections.

And, of course, it helped most for Clemens' nightly booty call.
