I too have had remarkable results with The Healng Code and The Healing Codes (I did get the Manual, which is now digital so less expensive). I've had all sorts of things heal. But you do have to keep working it. I do Codes every day. I really enjoy it, and love the results! I feel and look better than I did 10 years ago.
Yes, their marketing is a turn off. They don't neeed the hype, The Healing Codes work so well on its own, as users attest. In fact, what they market is not even their own products, which are pretty good, but other people's stuff. (There's a quick way to do a Healing Code, called the Q Codes, for instance, which I use when I do Codes for others.)
