I asked them about the positive offset and they claimed that it is a positive offset, that it never goes negative - exactly, because I learned too that if the zapper goes to negative offset it actually promotes the parasites.
I think you might be right in that I've increased their numbers by something, probably using this zapper/frequency genrator.
Thanks for the suggestions re: doctor Sutter. But what if my Tapeworms are only in my tissues - would the Zymex 2 work also outside the intestines?
