The word pheromone is derived from Greek and means a communicator of excitement. In fact, they work so well that some people call them aphrodisiacs. This particular formula has a woody, spicy, floral scent that women are attracted to. The book, The Joy Of Sex suggests that pheromones act directly on the brains center to heighten arousal, but at a level below the threshold of awareness. 3-5 sprays on your clothing seem to be sufficient. Best applied on collars, cuffs, and wristbands. Compact shape of the spray bottle allows you to discreetly take it everywhere you go, just in case. 1 oz.
