Yes, all flavours are PG based, so it says on web site, and yes definitely peppery-like throat hit. I'll mix berry one tomorrow as it shake and vape people said, see if it still there.ok, so you are obviously adding pg to your first mix to get to the 30pg / 70vg total (using vg nic as stated ) as there is only 7% flavour total assuming pg based flavours ?. and obviously less pg on your second mix as you have 15% flavour total on that one ( i'm asuming you're using pg based flavours ... correct ? ). and you are definately getting a peppery taste ?
