"Should be renamed "Instant Conversation". Very good base for many other pheros, I use it almost everyday. Makes the user more upbeat and conversational, seems to make others more friendly and talkative. Supposedly sexual in very high doses, haven't tried that yet, so far I've only got the "friendly vibe", which is worth it anyway. I apply a spray to either side of my neck and one to the chest normally. This is one product you really can't go wrong with."
