Applying IS and IG: same spot or separate, and where does cologne go?

What is the best way for me to apply IS and IG? Should I put one spray on the neck and one on the wrist (keeping them seperate), or should I just apply them both to the same spot together? Also, should I put my cologne on a separate place or right on top of the mones? Thanks..

I’ve personally layered (all on the same spots) with pheromones and cologne. I’ve also seperated. It didn’t have any noticeable differences for me except when its hot out. I work out a lot and for some reason anything on the chest or neck seem to diffuse quicker. I tend to balance it out between arms and neck/chest so that the heat isn’t the same, also I don’t get as sweaty on my arms. During the winter time it didn’t seem to matter to me, only in the summer, I experimented with everything on the arms but I just didn’t feel the same results as I do when I put them on in both.

For example, for AMMO I used to spray once on a wrist, dab together, then run down the sides of the neck, I did it again after it dried out and wrists/neck. I applied cologne (if any) afterwards and left. This was all before I started mixing and getting into single molecules. Our chems might be different so I’m not sure how it would apply to you. But if you have the same makeup then there shouldn’t be much of a difference.
