I don't doubt something beneficial happens to people when they pulse. Beck's copies of PCR tests shows that something significant happened. For those who do not know, PCR testing is a definitive FDA-approved methodology for detection of pathogens involving life-threatening diseases. We cannot argue with those reports. Speaking of which, I don't know how anyone will be able to accomplish "double-blind" studies. Electric current is felt on the wrist, unlike Sugar pills, which do not feel any different from real pills. My usage of the word "antecdodal" is due to the fact FDA testing has not been done, which might be necessary to determine complete safety. Efficacy is less of an issue for me. Something that is effective may not be entirely safe for everyone, like a lot of drugs out there. Just trying to cover all the bases.
