SteveO, i think 1:4 is correct. One of the pheros was massively weak and i only ordered 2.5mcg dosage. Fortunately, one of the MX in my stash had it at 12.5mcg and i was able to try 25mcg:7.5mcg with reasonable volume. Its never good to DRIP pheros.
I know i posted on here about a great kissing session i had, but i cant find it. Maybe i should PM Visionary…
