I got mine from the health section at Sprouts Farmers Market. I just make some. The VG is a lot thicker than one would think. That's, from what I've read, is the reason for the PG. I went ahead and made mine without the PG. It didn't seem right to use a petroleum distillate in my oil. Oils almost gone now but yesterday a salesperson at a vape shop told me without the PG in the oil is so thick it will burn up the heater coils.
How are you going to make your oil? Have you ever done it before? Experimenting is my thing. I would like to follow along and see how it comes out.
