I was testing recently pheromones in the cinema. I tried A314, IS, IO, IS+IO, IO+IH. The best fun was when I used IO alone, x4, 2 sprays. I sprayed it on neck. The moovie was “Drag me to hell” - horror-comedy. Girls that were seating around me were screaming very laud every time something horrible rapidly happened. 
People within radius of a couple meters were talking more than usual.
Conclusion: A-nol can lower the tension and provide more fun while watching horror movies. It lets to take it easier.
