HGH works very well and is very very expensive.... a cycle should only be for about 4 weeks, nothing more. the most predominantly side effect would be acromegaly, or a noticible thickening of the bones(notably the feet, forehead, hands, jaw and elbows) HGH can also enlarge vital organs such as the heart and kidney, and has been linked to hypoglycemia and diabetes. like i said before, it is very expensive! you'll be spending minimum 1000 dollars on a cycle for just a few weeks, your better off staying to anabolics...you dont need HGH at your age either.
