I want to thank very much who had answered to my questions about coenzyme Q10 and NADH. I want to ask you a new question. Is there anybody trying Growth Hormone for PD? I've red a book by an American doctor (Markus B. Lens), working now in Milan, where, with a lot of cautions, this therapy is proposal. Two Web sites (Life Extension Foundation and Dr. Fazzini's) say that it's might be helpful, when GH level is lower than normal. Thank you. Ciao! Massimo Paolini Roma, Italia [log in to unmask]
