While I have heard of folks using the zapper while on Miracle-Mineral-Supplement and I have not heard of anything negative as a result, it might be best to inquire on one of the Miracle-Mineral-Supplement forums.
Personally, I do not see any difficulty appearing between the two. If you find anything that would indicate otherwise, please let us know.
I have heard from many HIV positive zapper users over the years and the all love their zappers. Many of them use both ParaZapper and Beck protocol together.
