What he said is that he doesn't see high bromine in the urine using a mass spectrometer.
First off you and everyone here should be tickled pink that you have someone here with a mass spectrometer willing to engage in discussion. The amount of progress this community could make with such a person is beyond calculating... unless he is a scammer, which remains to be seen. Nothing you posted hints at that conclusion.
He never said it wasn't a detox; he said it wasn't a bromine detox.
The obvious and polite question is to ask him to test all the halides and a broad spectrum of heavy metals, then we can get some real data.
The rudeness of people on this site never ceases to amaze me... talk about looking a gift horse in the mouth.
