And considering how weightlifting at that age can prevent the bones from thickening normally resulting in early onset osteoporosis I'm going to bet that this sport is not going to be allowed in another 20 or so years. Once these kids grow up and hit 25 or 30 and have to start dealing with their fucked-up health, I expect the lawsuits to be rolling in. The East German Olympians from the 60s through the 80s are a great example of what happens when you delay growth in kids and then give them hormones. They grow up with some seriously fucked up health and mental issues. It's really sad.
