There´s only one way to find out which products work best for you and on the people you´re trying to get reaction from: try them out and experiment.
Maybe you´re a -nol person or a -none person. PI/w is the best product for -nol in terms of value for money for -nol. I would not worry about the minute content for copulins in it either. I´d definetely stay away from PCC and EW however-UNLESS the guy you´re after is bi.

One more thought, you´re already friends with this guy so he´s bound to be familiar with your own natural phero signature especially if he has some sexual interest in you! So go easy with the pheros around him in case he gets confused. good luck
