If it's the fda approved piece, I think it will come and go. It's expensive so not intended for direct to consumer use. It will be marketed at big companies.
the science is legit. It uses gas chromatography, which also means expensive running costs.
compared to resapp, it's only advantage as I see it is it was made in the US so already has a foot in the fda door (oh and that it doesn't have our BOD or pfizer running it).
I would still rather be on the resapp side in a head to head competition.
