I think I remember Porphy saying that the juice is made of specific ingredients and that a PG version isn't possible? (I could be mistaken, but, I remember it along the lines that it would upset the balance that is Boba's Bounty??)
Either way, I'm with Keith, I too have a PG intolerance. I can vape it, but only in small portions. AV's 100% vg is the best of all vendors I've tried.
