Well, AMMO is typically the suggested as an all around cologne for attracting women, but as you start experimenting with mones you will find what works for you. Personally, I have found good responses with A314 mixed with some socials like IS and IO more so than with just AMMO, but I have also had responses with AMMO as well.
Where are you planning on using your pheromones? If you are out in the club, I suggest AMMO, but if you are meeting women in the course of a normal day and would like to up the ante I suggest using something like A314 with some socials.

Also, you might want to try IG, which is a laid back alpha kind of feeling. It is like A314, but friendlier and there is no need to buffer it with any socials for an attraction setting.
