I used nbully’s calculator (Mix Calculator 10.0) with a target spray concentration of 15mcg and found that I needed .06ml of the chemset A1 in a 5ml togo. Sooo…I had a togo of Shine that was a freebie and simply added two drops of A1. I let it sit for a couple of days and viola…an unknown mix that mitigates pms. Since the A1 is a bit pricey I’m not risking a whole bunch of cash with this mix but it does seem to do the trick. YMMV and good luck
