steroids get a bad rap. Used responsibly, they can improve quality of life greatly.
Unfortunately, even if they are banned for the wrong reasons, it's probably good they're banned for adults.
We all know that the vast majority of idiot kids today drink and use marijuana, even though it's illegal for them to do so. If AAS was legal for adults, kids would get it and use it. And you'd have ten million teenagers with seriously screwed up endocrine function, sterile, liver damage, bitch tits, etc. And they'd all blame the gear. And they'd sue the companies, and some jury full of soccer moms would award the idiot kid $100 billion (or some other silly amount) for his troubles. As a result, steroid companies would go out of business anyway.
In this world - if you're smart enough to make good $, you are in a position to get test from a doc, or gear from another source. The 'barriers to entry' for these dumbass kids is very high.
