We are clearly using too high a dose at 5-40mcg or more regularly, especially since we are using enhanced methods of diffusion that would bring much more of it to everyones nose. I am thinking 1 microgram or even 500 nanograms should be tested. LAL has a 2mg/10ml oil dose which is 4 microgram per drop maybe also as a starting point. Instant Female Magic it seemed had around 13 micrograms per spray or so.
It seems to be detected however in the main olfactory epithelium of humans however and not the VNO as originally thought.
