Do Pheromone's work.?

Just asking as one of my friend's goes out around Sheffield, and seem's to have allot of luck with the ladies. You could be stood with him, and he seem's to have amazing luck. He's about the same good looking as me but seem's to have a built in magnet. I asked him and said he wear's Pherx spray. But I haven't seen him for a while but does it work...
