So many red flags I don't know where to start. My interpretation folks is that they are responding because they are trying to make a buck, which is so unprofessional when you do not have a solid proof and recognition from the literature, and before any trials.
I could go on and on, but this one smells worse than a lot of bad things I have seen. I had read the interview with FT, and that one also has plenty of red flags (for me at least)...
