nope, haven't tried his products, but every commercial cleanser is similar and I've tried ones with similar ingredients. I don't countenance using laxatives to get more than one BM a day, this ends up weakening the colon over time. As long as you have one BM a day you're not poisoning yourself so why do any intervention for more? Not all of us have extremely fast transit times. So lnog as every meal is coming out the next day that's good enough!
