Hi Julian and welcome.
Best advice I have is to try them each individually and at slowly increasing levels to see their effect on you and those around you. Then try combining them when you feel, you have an idea of what they do individually at a proper level.
Start with a spray of Instant shine to your Adam’s apple, then go to two sprays.
A314 to the wrists or neck behind the ears.
IFM is best away from your face, as it can have a depressive self effect to some men.
Ammo, use as any other cologne, pulse points, chest, and neck are good places.
