I couldn't find the direct link but TLC (the learning channel) and discovery had a story about a body builder who was in a roid ring and how he used steroids to archive the largest biceps. He served time in prison for selling roids etc..

The show was called "The Man With Exploding Arms" and his website is GreggValentino.net - Welcome to GreggValentino.net

Its pretty crazy, if you ever see it on its a very interesting story.
