"Question 1. Do they have FDA approval given that this is a 'genetically engineered strain'? (i.e., FDA approval for use in humans given you can do pretty much anything you want in research)"
No. They have done none of the preliminary work that would be necessary to gain CBER and FDA approval for any research program at all.
This is why I have said that if they were telling the truth, then they would be breaking not just FDA regs, but the Nuremberg Code.
Of course, they are not conducting any research whatsoever, human or otherwise, and never intend to.
This is a pure fraud, a criminal conspiracy to defraud the naïve and gullible.
