Layering pheromones question

I have been wearing two sprays of ammo and two sprays of IS on my neck. I have been doing this by spraying the ammo first on either side of my neck and then waiting a few minutes before putting the IS on each side.

Does it cause a different effect if you spray the IS directly on top of where you sprayed ammo compared to spraying next to where you sprayed ammo?

No, not really with those two.

Some of the MX’s are more heavily fixed with DPG, so they can have a little effect in how you layer them bit TBH, its not much.
