thats true what gutshot said...as steroids basically are a 'man testosterone' so when you young or going through puberty youre not or only getting small doses of this as youre growing. when you inject the steroids...you are giving you body the testosterone of a grown adult...which in turn like gutshot said...stops your growth...by capping the bones.

and please can you guys call it resistance training or weight training...as well weight lifting is more directed at the bodybuilding
