I think the human pheromone spray is a product that can enhance your attraction when it comes to bringing someone you want closer, but it's not like the oil based formulas. To increase pheromone fragrance attracting properties you should choose a scent that's suited to your natural scents.....
They've been trying to sell these products for decades, and they don't seem to ever catch on. If someone likes the way you smell, without adding anything, then there's a good chance that they'll be attracted without the need for anything else. Just keep yourself clean.
