One more comment on DHEA and NADH. Paul takes 100mg DHEA twice a day. He has muscle wasting and this has helped some. He does the same excercises but now can see some results, where before he took DHEA there no results that we could see. He does some upper body exercises. He took NADH for just a few weeks. I think it was 5 mg taken once a day. He couldn't feel any difference nor could I tell any difference. He has a prescription for the DHEA but it can be bought at some health food stores. We go to Peggy's in Los Altos, CA (800-862-9191) when we are in California but she mails stuff when we are here in Kauai. The cost of the DHEA is $36.00 for 25 days, and ours is not covered by insurance. The cost of the NADH was around $90.00 for not too long a supply, again not covered by insurance. Jan Potter for Paul
