In response to your message:

I have increased the zapping duration to 2-6 hours and sometimes longer every day. I sleep with the zapper on. I've gone through a lot more batteries in the process!

Beck did say that in the two hour cycle ALL of the blood flows through the arm. I don't know frankly. I have considered pulsing on the ankles pulse points).

As I understand it, the purpose of pulsing is to move the virus from the lymph system to the blood stream where you can kill it. It is not necessarily to kill the virus in the lymph system (addressing your concern about virus in the lymph system). According to Beck's own research, just zapping alone wasn't enough to kill the virus (which you corroborate) but you don't seem to acknowledge the other parts of the protocol.

I use SOTA Instruments for all parts of the protocol and I think many others can speak to the quality of their products. They seem top notch and consistent with the Beck studies and requirements.

You and others have suggested longer zapping periods and I will try this. I will work into my routine one weekend a month where I wear the zapper the entire time. Before I do that I need to go get tested (to see if there is a before and after affect).
