Really, when I read that trash this morning, I wanted to throttle whoever wrote it and slap his/her editor. A typical example of yellow journalism. It presents a boy who uses protein supplements and misleadingly conflates that with the side effects of steroid use. Repeatedly and deliberately. Also notice how long is the list of just plain stupid retractions and corrections they've already had to attach to the end of the article, as of 0600 this morning.
The article also implicitly states that weight-training and dietary control are wrong because the only legitimate route to athleticism is genetics.
I'm sure a few kids are harming themselves through overtraining and misusing supplements. However this article misses the mark entirely. And it's hardly an epidemic. When I happen to drive past the high school, what I see are hordes of shockingly obese kids waddling down the street, sucking on sugar water as they go. That's the epidemic.
