I think teens Don't consider the dangers of juicing at a young age because its the last thing on your mind, when your trying to get big enough to be noticed by a division one college to play ball. The pressure from the coaches too, they wont tell ya to do it but they don't say not too. One went as far as to telling me they can't afford to test for them. I don't agree with them taking them that young. But IMO that's why we see it the rate we do.
