I believe the magpulser is better for pumping lymph nodes and also effective for pain relief of the neuromuscular type. The clark type zappers are better for killing viruses and parasites. I also like the Blood Electrification devices a lot like the Gozilla for localized reduction of parasites and germs. You can check that site out below. Probably the most reasonably priced and effective unit you can buy for cleaning blood and reducing parasites is the Godzilla. I like the Silverado Deluxe and Terminator 2 for regular zapping and portability.
