Has anyone had dates or approaches fail while wearing pheromones?

No, not that you don’t need to, remember that 1/3 of the total pheromones in AMMO only consists of Androstenone. All I’m saying is you probably won’t need a lot of it to be effective. Usually that is the reason people say to find your sweet spot. Once that’s established you know how much pheromones you could use.
