I found some interesting information on Human Growth Hormone... some of this I already knew, but some I didn't... and I am sure there is more out there... seems there always is http://www.growthhormoneclinic.com/ I knew as we grow older we don't have as much as when we were younger, I guess not so much that we don't have it, it is harder to get to or to be released... The Protein Power Plan trys to increase the GH so it is easier to lose weight...
