So I was reading one of my family members articles and in a past issue he discussed an oral GH pill. The pill increased muscle mass in elderly people, but I am guessing it could have some decent bodybuilding uses.
Apparently ghrelin also can help improve brain function and reduce stress-induced depression.
Anyway, seemed like an interesting drug and thought I would start a discussion on it.
