I tried my P104 yesterday, not sure about the results. My husband, myself and one friend each used 2 sprays (sorry dont know the concentration) to the wrists. There were two other friends present who dont know about pheros, both men. We had been drinking champagne for a few hours before we added pheros to the mix. We had been having a fairly positive, productive, casual type meeting. After the P104 came into play everyone seemed to get really lethargic. I started to get waves of mild nausea and headache. I also found myself getting somewhat irritated. that could have been the company though. I washed it off after a few hours but still felt icky. My husband used a little ifm on me though and that seemed to help
