The Beck Blood Purifer will kill most of the pathogens in your blood. It runs at 4 cycles per second.
The reason for the low frequency is that lower frequencies penetrate the body to a deeper level. Even so, with the Beck Blood purifier the current doesn't go much further into your system than a few millimeters. Hence the recommended attachment points to your two pulse points on the wrist.
A higher frequency device will tend to not go deep but keep closer to the surface of anything it is attached to. It will more or less travel over the skin and not penetrate as much. What the hell good is that?
With all that being said. The Godzilla is a device everyone says is stronger and etc. etc. but when you run a higher frequency it's simply not getting through the skin barrier and into the blood. Last, I researched the device and haven't found any real, tried and true data to support this device's promises of better performance.
From personal experience the Beck Blood Purifer is very powerful and kicks major butt. After 11 months of using it I still can't bring it up to full power.
I've used the Beck Blood Purifier for 11 months now for 2 hours a day. During the first two months I had die off like no tomorrow. I got sick, flu, colds, laid up in bed for half a day and so on.
After that I haven't had a cold, flu or any kind of sickness.
I looked at all the devices out there and finally decided on the Full Bob Beck Protocol, the Dr Hulda Clark basic zapper and Tens Machine. These three devices are doing a very good job for me. I don't get sick anymore, my parasite levels are down to a level where they don't affect me and I do not have anymore body pain.
I think that is pretty good considering I only spent $400 USD for the whole shooting match.
Last, there is a great deal of information available to you on the internet regarding the Beck Protocol, Basic Hulda Clark Zapper and Tens machine. I researched for months and printed out all the information I could find on these units and also downloaded all the videos available.
If you actually read and watch all the information available you will be spending hour upon hour day after day becoming educated.
