Oh. I agree with that. The whole thing is unproven hokum. Dealing with ice crystals might be the only part of the process where they've done some research and can put an argument together. And indeed, that might be because it's one area where they've been hit with some criticism which would have threatened their revenue stream.There is no non toxic method currently known to science to thaw out cells and the tissue they make up without irreparably damaging them.
Again, Im a layman and no expert in any of this, but that is the bottom line.
