This is my first time using pheromones, I wanted to try it and see if it would help give me that extra edge in my game. I must say I'm unimpressed with the results thus far... the one girl I'm seeing commented that my new cologne "smelled like a port-o-potty", the other one commented that she liked my other cologne better. As far as attraction I didn't notice anything out of the norm other than my dog craving extra attention. Maybe a combo of my fav cologne over Chikara? Also, how many sprays are optimal per application?
