Yeah, it's a little too late for the GH as far as adding height. Now if you were to utilize it right before puberty, you could have made it to 5' 10"- 5'11".... I write this "tongue in cheek", but it is pretty much true. If you were to use it now, your bones would fuse much quicker than what is allready predestined. Welcome to the 5'8" and under club!!! We have fun here... we still get pussy, but not that premium pussy, we look better as bodybuilders than taller guys, and we usually live longer....
