From what I've read briefly, it seems he uses small silver electrodes which ionize in a small amount of silver ions through the skin using a small current.
Beck mentions not to use table salt because it will ionize the toxic salt compounds into the skin and surrounding tissue.
Possibly ingesting silver colloid and mag pulsing would mimic a similar effect?
Might explain how he grew his hair back, by applying silver colloid then the mag pulser put a small electrical current into the tissue stimulating it?
Sounds fairly simple to do, but I will look into it in the coming months.
