The more proof the doctor gets that the treatment is safe and effective, the more it makes sense for the doctor to charge his patients.
He claims that five years ago he successfully completed clinical experiments on the restoration of lost hearing, but when I asked him to show me, I was ignored. This clinical study has never been published and he claims this was five years ago? And his best answer is that he hopes to publish in the coming years, but is in no rush?
He did it successfully and never published it?
But he won't show anyone this apparent study. If he wants to be taken seriously he should have published these results into a medical journal already. He's happy to take everyone's money but is offended whenever anyone, rightly, questions him.
He seems to like people who don't query anything or ask for scientific evidence, and his price also seems to be pulled out of thin air. There's no logic to any of this whatsoever.
