i use one good spray of ammo to the chest or neck and 3 to 5 drops of a314 with good results. i put a314 on my chin ,back of ear lobes and one drop to the crown of my head. this works good for social environments and at work with me. lots of ioi from the opposite sex. some times males seem a liltte intimidated. more than one spray of ammo seems to stong for me if used with a314 but i quess for some people it might work if it was that strong.
