Which magnetic pulsers are you saying are better for fighting infections? I've tried a zapper in the past which also had little effect. I've never tried the blood electrifier, but that would not seem to work in my case since my infection is not blood borne.
The MPG5 was designed for the "Beck Protocol". Everyone has pathogens in the blood that your immune system is fighting. If you cleanse the blood your immune system will have more resources to fight the infection. If you take Colloidal Silver you are putting yet another nail in the coffin of the disease. Ozonated water removes dead pathogens and oxygenates the body. They all work together.
The MPG5 might work over time but it is designed to keep you from reinfecting yourself from the Lymph, Brain, Liver etc.
