Leather. Why leather ? Because leather IS skin. Pheromones are an evolutionary outcome of… skin. The glands located in… skin, the largest ORGAN in/on our body that has a multitude of complex life protecting and life support functions…
For that reason I believe, my best rates of diffusion and most consistent results have come about when pheromones have been absorbed into leather and re-released as they would from a collagen matrix substance.
I discovered this method. Winter technique. Make a strong mix of XYZ, pour it into your hands, and rub it all over your hands. Then put on a pair of leather gloves, natural fiber lined (wool or cashmere), thin deer or goatskin are the best, city gloves that can easily fold up and fit into your pocket.
Wear these around for an hour until the -mones diffuse into the leather, you’ll be charged up for about a week.
You could also go to a leather store and buy a sheet of medium weight hide, and use a sharp x-acto knife to cut a rectangle that could discreetly fit into a pocket, or an couple of extra leather belts. Take a -mone solution, put it and the leather into the freezer for a couple of hours (you don’t want everything evaporating away all at once), then quickly swab the -mones onto the leather with a cotton ball saturated in the solution, then stuff the leather and the saturated used cotton ball into a large Ziploc freezer bag, squeezing all the excess air out. Let this sit a room temperature for 48 hours while the -mones diffuse throughout the leather and reach an equilibrium state. The belt will then slowly release a “force field” of pheromones around you slowly and evenly…
Start with low concentrations and work your way up until you find the ideal dose for that particular type of leather (tanning chemistry varies, although all tanning functions by cross linking collagen), the chemicals use to finish it that affect absorbtion, etc.
I have found this approach to be FAR SUPERIOR to putting an exterior coat on human skin, that releases too much at first, then tapers off too quickly as the mones have nowhere to go except by evaporation.
Your best belts will be the thicker hide belts that funky leather stores sell, the less effective are the skinny hard leather corporate jobs.
For extra credit you can get yourself a vacuum sealer, such as the infomercials demonstrate preserving lamb chops for the coming millenium, and vacuum pack your belt. This will drive the pheros DEEP into the structure of the leather. Before you do this, though, you must pre-pack the belt in a bag, and freeze it overnight(with the pheromones already applied) and quickly pump it cold, or the pheromones will be pumped out with the air.
