DeVany has found a system that works for him, it doesn't mean that he understands physiology. Watch the CR-IV DVD and see how some of the biologists react to his misunderstanding of what they're talking about.
But, I still found value in his stuff and subscribe to his private blog. Then, I had three of my comments removed on both the private and public blogs about him stating that the DVDs will sell for $59.99 and then not following through. I don't care, I would have paid $139.99 since I'm a curious guy if he had said it would cost that all along. I just expect grown men to follow through with what they say they're going to do. So, I've lost a lot of respect for the man, regardless of the accuracy or inaccuracy of his information. I won't be buying the DVD now, so I guess I need to pick up some of the stuff this site is selling now.
