Do pheromones really work ?

I tried the ones in a bottle, didn't notice a difference. I did notice when I would wear different colognes, I would notice different reactions. I notice there were some colognes that had women going crazy at work. I notice when I would wear good cologne I would have about 2 to 3 girls at work giving me compliments. Its like magic because I would notice more girls starting conversations with me. Even when you don't notice, if a girl likes your cologne she will tell other girls and it makes you attractive in a way. Pheromones didn't work for me at all but cologne did.
