Does anyone have any recommendations for 100% PG free flavor concentrates to buy from DIY Vapor Supply that are either Real Flavors or Natural Flavors? I'm allergic to PG so I can't have anything with PG whatsoever, not even a drop. I was looking at reviews for a couple of them but there's barely anyone commenting on each flavor concentrate or rating them on the site so it's hard for me to choose stuff. Let me know what ones yall think are good or great, the more insight on the PG Free Flavor Concentrates from DIY Vapor Supply the better.
