I am 50 years old, 511, 225, in pretty good shape. Competed in bodybuilding up to last year )Masters). I have a torn rotator. will be doing surgery at the end of next year (2006), I am currently doing TRT. I was going to do 4 iu's of GH up to my surgery next year. Would that be too long to be on GH? I just want to keep some fullness until I go under the knife. Very limited on shoulder and chest exercises right now due to the torn rotator, I just do light set to get a pump. Thoughts????
