In some ways, steroids have been a part of mainstream media since the muscle-men of the 1970s. The lure of a "buffed body" among teens, however, is more of a recent trend.

That same survey found 57 percent of teen steroid users were prompted to use by reading muscle magazines -- and there are at least half a dozen of these magazines nowadays.
