I have't done the ultimate fast yet, but from what I've read it seems to be very effective. I believe that the combination of fasting + PB-shakes will do far more than for example just taking Oxypowder , colonix, etc.
The user "hopinso", who is very knowledgeable also highly reccomended the ultimate fast, because it gave him the best results.Maybe you can find some of his posts. I would say the ultimate fast is the next best thing after the incurables Program.
I think I read one of your posts on Uny's natural healing forum and I think you mentioned, that you are from Germany. I also live in Germany. Do you know how I can get Bentonite in Germany. I've searched, but without success. Or do you have it shipped?
