ok ive heard that HGH makes your bones grow and will make you taller. ive never taken it so thats why im asking all you that have, did you get any taller or have any wierd side effects like longer toes or fingers or cave man fore head? also how does it make new muscle cells that are not their all of a sudden appear and make new ones. ive always been told that you can never have more muscle cells than you were born with, so how can all of you tell if your growing new cells?
