I think gh and the mill of peptides serve a wonderful purpose for healing of tissues for tears, strains, sprains, etc, but for certain things like alignment and mechanics of movement, or various growths like bone spurs/other mineral deposits, scar tissue... manually correcting the injury by way of surgery is sometimes the only option...
case in point... I had a neck fracture back when I was 17 from a car accident and two of the vertabraes were dislocated (subluxation) as well as fractured (C5-C6)... I wore a halo (head/neck traction) for 3 months and altho the fractures healed within the first month (I also took mega doses of glucosamine/chondrotin daily which I think helped), from all the various scans I had every following month to monitor my progress, the ligiments that had over stretched (as it was explained to me in basic english by my neurosurgeon) but didnt break (to basically keep me alive and/or not paralyzed) healed but never regained original elasticity to keep everything back in its proper alignment so surgery was my only option to keep the vertabraes in a non "floating at will" state...
I did the fusion and been happy every after (of course after rehabing all the muscle and soft tissues in my neck to get rid of the "rubber neck" LOL). I still have the little dog bone shaped plate with two screws in place even tho my doc told me after around 5 years i could have it removed if I wanted since the bones would naturally fuse together thru calcification...
