i have many reasons i'm starting HGH soon, but one big one is the increase in collagen synthesis which in turn improves connective tissues. i have issues with my rotator cuffs. i've had the problems with them since i was about 15 and i'm 28 now, and nothing else i've tried has really helped them much. just wondering if any of you have had personal experiences where this stuff has dramatically helped any joint issues you have, particularly rotator cuff related? also, how long did it take to really notice a difference?
