Depending on your eating habits, be it junk or healthy, I've used the colosan and the oxypills with good results. I drink lots of water from 4-6pm, about a gallon then take the powder then chase it after a few minutes with acidervin, I think the water helps draw more decay out. The first time should take about 15-45 minutes 2-3 times, as you progress it lessens and you will notice, about 7-10 later you should be cleaned out, especially if you can go 2 times a day on it. 1st few nights sleep with a towell.
hope this helps
