I take Oxypowder , same thing as homozone. I dont have a clear answer for you. However, it looks like no one is responding to your post. So I will tell you what I know.
I took Oxypowder for a couple weeks while i did P&B shakes. It did GREAT. But I have read on other posts that it does not clean the colon. That is why I added the P&B shakes.
Once I finished that cleanse I backed off the oxy because my stools were not watery or black anymore. Im not sure how long to take it. I started 2 months ago.
You may want to post on Andreas forum since he recommends this particular cleanse.
