so if you intend to use P75, I’d make it well buried in a “nice mix” and a slow release substrate… P.S. for a good lingering vapor cloud, Jojoba Oil seems to be a solid choice, although it remains oily… so put your pheromone-jojoba streak where it won’t matter if it gets on clothing… I’m playing around with Jojoba (a super stable naturally esterified oil)/ Monolaurin (a biologically OK waxy coconut fraction)/ C12-C15 alkyl benzoate (very light cosmetic ingredient, smooths well to skin, reduces greasy “unctuousness”)… anyway, a wee pinch of P75 probably gives that hint of “wild teen guy exploding with hormones” signal… which MAY trigger (not unwisely) a self protective, radius increasing response if used in excess or out of balance… with a good offsetting of empathic -mones like P74, EST, Nols, dienols it may give a slightly goofy 
outrageousness to the proceedings…
