You have been around for awhile so you know of all the different protocols which are suggested here.
I personnally follow Andreas Moritz views. If you want to read his views I would suggests to buy his book Timeless Secrets for Health and Rejuvenation http://www.ener-chi.com
In the left bottom corner of the website you will find an index with all the subjects he writes about. Also read his forum so you get some idea what he is about,
Ask Andreas Moritz .
His views are sometimes different. He feels when you do bowelcleansing ( Oxypowder ,not P&B shakes) and liverflushing that will take care of parasites too.
He improves health with the right lifestyle, but not with supplements.
My health completely changed by doing liverflushing. Later I added the lifestyle etc.
