Interesting. I've heard the opposite. I think the fact that chikara has 7 pheromones in it, I interpret that as ... it will work for a wider range of women, but not work as strongly.
Wherein, if you wear only 1 pheromone it will attract a certain type of girl.
I could be way off base, but as you know certain women are attracted to certain pheromones. I guess it has to do with the subconcious connection humans use when choosing a mate.
I watched a long ass show on it @ Nat Geo, how we choose mates by a subconcious genetic connection, picking partners who have differing immune systems and all this wacky stuff.
I'll just keep lifting weights and gelling my hair. It seems to work
