I\'ve read a ton of suggestions on how to use pheromones with cologne but I\'m still unclear when using a pheromone such as PI do you put the pheromone on one location and the cologne on another. So if you put a drop of PI on your neck do you spray cologne somewhere else or is it ok to spray the colgone over the same place you have the pheromone. Which pheromone is the best obviously PI is the most expensive due to the amount of pheromone you get but are there other pheromone/cologne combinations that are just as effective for equal or lesser cost. Just wondering any advice helps.
