No matter what you take, is what you do to yourself that will make a difference between fast recovering and a couple of complications. Go with the Doc advice and take it moderatly and intelligently. No pressure on your kneck, no quick movement , try to sit down when you do dumbells or barbells. I think that
HGH or some low
test cycle will speed a litlle the recovery, but try to have a professional advice on the risk of having trouble with your immune system and the effect of high blood pressure on your new bone part. Testosterone is known to improve the immune system and prevent bone loss.
