Guy sir can't give you the exact ratios (trade secret) and you can't customize the blends on what Vapor4Life sells, but can give you the ranges on the different juices-
Premium (what's in cool cart prefills)- 100/0 pg/vg min, 80/20 pg/vg max.
Wow- 70/30 pg/vg minimum, 50/50max
Recently added wow flavors- 70/30-60/40
Wow VG- 0/100 The wow vg contains no pg in any of the flavors
Hope this helps sir.
