I had the same exact surgery as Manning. I used GH during my recovery. I have never been able to get back the same strength I had prior to that surgery/injury. I still have small quirks due to a bruised spinal cord. Did the GH help me? Maybe in a faster recovery. Did it make me as good or better post surgery? No, maybe 90% on my best day. He may have used it, I really don't think he did but I'm a huge UT Vol fan, so my opinion is skewed. But if he did, more power to him. That's a tramatic f-ing injury, having a damaged spinal cord is equal to a brain injury. Except instead of controlling thoughts, the spinal cord controls motor skills. And being a QB at the highest level it's amazing he's even still able to play after that injury much less being almost 40 years old.
