Illegal Steroids Still for Sale.

Since the first CBS News story aired last March, the Food and Drug Administration (FDA) has begun to crack down on designer steroids like Tren, but as CBS News correspondent Kelly Cobiella reported on "The Early Show," they're still very available -- and very dangerous.

Using a hidden camera at a supplement store, Cobiella spoke with an unidentified salesman who, referring to Tren said, "I saw a decent amount of size -- and it leaned me out."

Cobiella says that, since Part One of "The Early Show"'s "Early Eye" investigation on over-the-counter steroids aired Monday, there's been plenty of talk at supplement stores, in gyms and online about so-called "prohormones" such as Tren, including discussions of how they work, and the effect they can have on organs like the liver.

Maryland Congressman Elijah Cummings told "The Early Show," "I would guess that 85 percent of the people know exactly what they're doing. There's been too much publicity with regard to this area. They know."
