My wife has been experimenting with P103 for quite a while now…
Experiment: P103 at the office
Target: Boss, male, sits 24-36" away
Quantity: varies
So She started the day by going in to work without any pheros on at all. The Idea was to survey the land. As usual, her boss was in a grumpy as hell mood. During break, 2 hrs into her shift, the wife goes out the car and applies 4 sprays P103 @ 10mcg each. Within 2 minutes of my wife’s return to her desk, the boss had a nice big grin on his face. Within 10 min. --I shit you not, he was singing-- kill da wabbit kill da wabbit… And telling jokes. The wife ran this experiment with 2-4 sprays of 10mcg P103 5-6 times more with similar results. P103 rocks!
