absolutely gh will repair connective tissue damage!!
That was the reason i first used gh.. to repair damaged knees and a rotator problem..
6 months of 2ius EveryDay and i have NO knee pains anymore (except when it rains or i squat real heavy) and my rotator does not lock out anymore like it used to, so does it work theraputically.. ABSOLUTELY!!
in fact gh is more designed for recovery and therapy rather than building muscle; well it is better for the former.. combined with aas it will get your past genetic potentials and it does burn fat the longer you are on... but it can not be beat when it comes to therapy!!
Now, anavar and gh

that is the most synergistic combo!!! That is what i used my dear.. gh and var for the 6 months i mentioned above! They just work so well together.. low doses over longer periods of time is the key! 10mgs a day..
there is tons of research you can do on both as well, just to better educate yourself

good luck.. you are gonna love em both IMO!!! and the fact that you are under a doctor's supervision is even better!!!
