Anyone?
Not sure, I know it works for allergies. On safety, ask Sammy or Dream.
@SammyG is there protection against tumors??
I’m assuming since you still post fairly regularly that there was no tumor development in all this time? 
Fields like senecesent cell removal or anti cancer are great for preventing cancer.

Oh, man, f… It, this is the last time I’ll make this experiment.
I have tried using HGF with some earbuds, for 10 minutes, while having a throat constriction (maybe anaphylactic, maybe not, Idk), and it was quite bad, maybe a slight difference, but far from the Amazing and fast results which I get using speakers or the phone speaker.
It’s way more efficient with speaker, at least for me.
Btw, I’ve already done it successfully a previous time, a couple days ago or so, so, yeah, even using earbuds can give some effects, after some looping, but no way near the fast and strong effects I get from speakers.
