I've read posts on other forums about people warning those younger than 25 to stay away from HGH altogether, with warnings of "messing up your endocrine system". While I'm sure anyone can screw up their body's balance with massive levels of HGH, I'm more interested in what the negative effects of a 20-25 year old person using 2iu a day for 6 months? Why bother with such a low dose some may ask, especially at that age when your body is supposed to be producing lots anyways? Mostly for help healing some injuries that just seem like they need a boost. sounds stupid? just sick of always these dumb injuries from older training days sticking around and never going away no matter how much rest and exercise modification, rehabiliation, etc. etc.
