i havent done a master cleanse so im not really qualifed to answer but i will give you my experience. i did a 30 day juice fast and used the master cleanse liquid often thru my fast. when i here you say would it be alright to use oxyowder on master cleanse i often think of the two trains of thougth.

one is you do it strictly to the letter and i mean by following the guy who discovered master cleanse sorry cant think of his name - is it stanley someone (sorry it's late at night).

two is doing what works for you.

on my juice fast i tried to be really really strict nothing but juice and water. well it just didnt work for me i had to add veggie broth and herbal teas and i was so worried about not being pure but it got me thru my fast adn really worked for me. the other thing i struggled with immensley was laxatives i tried enemas, herbal lax, smooth move, physilium husks and not taking anything. well after my fast i went on the oxypowder program (7days) and i can honestly say i wish i had this during my fast.

however i did reconmend this to another friend of mine and she did not have very much success. making sure i am being somewhat objective here.

so my advice is give it a go if it dosent work so be it and if it does great.

i think fastign is an amazing thing to achieve and elimination is a huge part of it so whatever you can do (obviously within a realm) to make it easier on you should be a personal choice and dont worry about what is and isnt strictly correct.

hope this helps somewhat and good luck go for it. my favourtite (dazzle) saying is this is an amazing gift you give yourself dont look at it as a restriction more as an expansion of your experiences and a path to better health.
