Sorry, I didn't quite get your meaning
What I meant was theoretically if a doctor did agree to it they would be responsible for their actions as well of course as whoever asked them, not that I'm suggesting anyone should. However the doctor would be legally responsible for any harm caused by an unapproved treatment if that could be proved of course and it also depends on the countries regulations
Apparantly some do use or have used IV Miracle-Mineral-Supplement in Mexico however, I don't know about any elsewhere
Doctors do things all the time that are harmful and they usually get away with it but they do it with approved methods sadly.
I myself keep well clear of doctors these days and wouldn't ask them to do anything if I could avoid it
