As I have just mentioned in a post left here, I am definitely finding that different frequencies cause different side effects and benefits. For example, wearing a zapper at 30 hz at the waist day & night absolutely increased my energy levels a lot (after the intial strong die off at just an hour of wearing, & build up on time). However, wearing a 15 hz zapper, purchased months later, helps me with neuropathy in my feet.
I hope you don't just rely on zappers, though. Different bugs and pathogens respond to different treatments from what I am experiencing.
