Does it matter what you use first when you layer on the same part on the body? For example say you want to put Ammo & IS on your wrists; would you spray Ammo then IS, or does it matter which goes on first? 
Let me just say when it comes to applying mones it should never be able to get that technical 
Actually a few other members and myself tested this theory out. It possibly increased hits but was such a mild change it ended up not being worth the bother.
Plus there is to many other factors to consider like molecular weight. humidity, diffusion etc etc …

I’ve actually divided my neck into sections that get certain mones to them.
I’ve tried doing this. Be VERY careful though. With 2 mones it works a treat, but any more (for me personally) my phero cloud is a mess. It sends of too many conflicting signals. Both men and women don’t know how to interpret it, and i generally get confusion from people.
I keep to having 2 mones front of the neck and a third back of the neck. Having them on my wrists does nothing for me.
Instead of layering I personally take the mix on skin approach. what I do is lay out what I want the mix to be, then spray it all on my neck and spread it around with my wrists… this both mixes it so everything is everywhere, and puts it on my two main point which are my neck and wrists
If you want different spots to have different effects I suppose you could do that but the cloud is going to be bigger than the distance from your neck to your wrist so I really don’t see much of a reason for it.
Tish is right about diffusion being a bigger factor. That’s why since I like my signal to be A314 based I use three drops and usually one, but never more than two sprays of other products. A314 being oil based diffuses slower and if I outnumber it with other products the signal seems to get lost.
I have to agree Rad… i’ve been finding the exact same thing… A314 makes for a solid base for other (but not too many) additions.
