Ok many times we have warned young people from doing gear on this forum and one of the many concerns is closing of growth plates.....what exactly will stop?
1-Height growth?
2-Bone density growth?
3-Bone length?
4-Natural Muscle growth?
5-body organs development?

What exactly is gonna stop! If someone does juice when they are very young, will they never be able to build muscle naturally unless its on juice? Will their bones stay prematurely smaller?
