Is it known how much PG is carried by the flavors we use by brand? I ask because my first DIY was mainly TFA flavored (did have one FW flavor in it though) 70VG/30PG & was WAY thicker then my second recipe, which was an LA-flavored recipe & was made at 75VG/25PG & seems really thin. I'm just wondering if LA flavorings are higher in PG than TFA or not?
