Found it!
MHarris:
"Yes, the sprays will tend to be more obvious because of enhanced diffusion created by the delivery method and the Neroli/Orange “cover scent” package used. (which was designed for us by the same folks who designed Andron for Jovan more than 25 years go, as well as a bunch of other famous colognes, including Drakkar Noir)
The downside, of course, would be length of results. Oils diffuse slower and give you muted effects compared to our sprays, but upside is that they last longer.
Let me know how long you’re seeing effects, and if any of the effects differ from oil A314 itself.
I couldn’t make an exact duplicate of A314 in spray form, since the diffusion curves of the pheromones differ in this format – i.e., I had a use a little more of some mones, and less of others.
Adjustments may still be needed to achieve the very same effect."
