NPA for men is a new pheromone Additive containing about 5 times the androstenone of the old Pheromone Additive just for starters. This new pheromone additive is also designed to be added to your own favorite cologne or after shave.

It comes in two separate and scientifically based formula, one for men and one for women. This one is very concentrated! Only to be used for mixing with cologne or aftershave. NPA comes in a small 5 ml and large 10 ml bottles, both with a convenient eyedropper lid for convenience.
