Hi Volta Fan
I've tried the original Master-Cleanse
as well as version of Master-Cleanse
+ P&B Shakes, and the original Master-Cleanse
works best for me.
On the last 2 days of my 14-day MC last year, I did take Oxypowder
(4 capsules with a glass of water with juice of half a lemon), just to see what I would get in my bowel movements. MC does loosen up the gunk on our intestinal walls and the Oxypowder
helped me get rid of that gunk.
So, for myself, I would use Oxypowder
again but only at the end of my MC (as an extra cleansing) but not during the main length of the MC.
