I also am not particularly convinced by the MP claim. What no-one else has noted yet is that the Toxin Absorber (P&B) contains apple pectin - no wonder it comes out the other end rubbery!
I'm on my 5th day and have passed a fair amount - I just feel rather sceptical of the notion that much of it is MP and not simply the P&B. It comes out foul-smelling because all waste comes out foul smelling.
I've followed the programme to the letter, but in my heart-of-hearts I just don't feel very convinced. I wish I did!
