If you are new to the pheromone perfume scene and are looking for an economical price then IR is for you.  The versions come in 3 different fragrances (Seduce, Invision and Desire)

For the human pheromone professionals  out there, these spray bottles have screw-off caps making it very easy to add your favorite additive.

I have seen women wear this type of pheromone perfume out in the club scene and I can tell you now that it successfully attracts men easily.
