I was considering trying Colon Blow but instead, copied the ingredients & instructions off of their web site and bought something comparable at the health food store for less $. Since the instructions for Colon Blow say to do a liquid fast, I just did the MC, taking 2capsules herbal laxative with a P&B shake, 3 times a day. At the end of day 1, I had a fairly major blow out, but it didn't exactly look like mucoid plaque, although it was holding its shape fairly well. I decided to continue it for a couple of days, ending up doing 5 days of that regime, passing what looked like it could be mucoid plaque, holding its shape but not firm or black. On the last day, I did an enema, and I am almost postitive that I passed a goodly amount of MP: firm and shaped like my intestine, but it wasn't black.
