Most pheromones won't work too much magic, what they sell on the street is mostly watered down and less effective, the stuff that could really work is not available for the common customer and prices are beyond what I think reasonable for anything. What you get in the store is not really effective enough to boost your success (I know this for a fact).
My suggestion, forget about all the chemical stuff, you have enough of those in you as is to get the ladies. Work on your body language, get a confident look around you, and I guarantee you'll get more looks from women than you could ever get with synthetic pheromones.
