The Paratrex is a 6 week cleanse, it is one I am currently doing as well, you will need two bottles to complete the cleanse. I have also completed a
colon cleanse and a liver gallbladder flush, in preparation for this cleanse. Just by doing these cleanses first, it should help with the die off from the parasites. So far I haven't had any complaints with the Paratrex, it has gone well. I have to say, I used Oxy-Powder to complete my colon cleanse, it is like a night and day difference in the way I feel. Feel free to checkout my
cleansing blog site, it has all my cleansing experience, and it may be of some help to you.
