I purchased his longevity now program. To be honest when it arrived I was going to send it back. A pack of CDs and a book didn't seem worth $600 (Cdn). It comes with a 30-day money back guarantee. I let it sit for a couple weeks before I really got into it. After going through the book and just touching on some CD info I knew this info was (is) a keeper. Lots of great information. I can't tell you how many times I have referred back to it not just for myself but for my clients (I'm a nutritionist). I am loving the information and knowing more about superfoods, herbs, etc. It's his research wrapped up into a nice package. If you are exploring or are into raw foods and superfoods, and want to give yourself the greatest health ever.....then you won't be disappointed. I'm not!
