I know how hard it is to deal with nagging injuries...it really sucks. I've been looking into getting my own injuries to heal, and there is no better hormone to take than hgh--if anything can assist your body's healing it would be hgh/IGF-1. Deca also seems to help people, and testosterone is positive as well.
But I honestly don't think that any of them will necessarily heal your injuries and make them like new. I can see that they would help...maybe your injuries won't hurt as much, and there might actually be a strengthening of the tendons and ligaments, but I don't know if any of these will give you brand new joints unless maybe you run hgh for a year at 20IUs a day.
That's what I know...it's not as much as I'd like...the problem is that there isn't much in the way of articles published in medical journals that have investigated this topic adequately. There are definitely articles showing how these hormones help connective tissue proliferation, but I don't think that there are any articles that specifically take MRIs of damaged ligaments and joints of people on hgh or testosterone and compare them to controls on nothing...you can only do your best, run your cycle, and see what happens.
My opinion of including the testosterone? I probably wouldn't run it if I were just looking to heal injuries. Most of testosterone's positive effects on connective tissue seem to be because it inhibits the somatostatin, and increases your hgh naturally...if you are taking hgh already, then it might not be worth it unless you're looking for testosterone's benefits on other aspects of your physiology (muscle hypertrophy, agression, etc.)
