I have been using Oxypowder for over a year now. My elimination track was completely clogged from years of abuse. I started out with a full cleanse of Oxypowder and then had a few colonics. Even though my system is still trying to recover, at least I'm about 90% better than I was a year and a half ago.
Oxygen based colon cleansers are not for everyone. I have noticed that men seem to do better with the fiber cleanses than women. But if you do try and are successful with the oxygen cleansers I would say you are on the right path.
Yes, I did lose weight initially on the Oxypowder and there is no doubt that my system is eliminating better. I still have a way to go though as I'm fighting a family who are in love with Nacho Cheese Chips and other processed delicacies.
