Well, while most juices I prefer are heavy VG, alot of them still have some PG, like 10-20%, due to whatever reason.
The 100% VG blend from High Caliber promises no more than 5% PG in their juice. Every juice Ive tried from High Caliber, has been solid to wonderful. I basically dont even worry with these guys anymore, every juice is flavor correct based on its name, without wierd exhale notes or aftertaste. For me anyway. You can get them 50-50 from Electronicstix, and 50-50 or 100vg from MyVaporStore. I can vouch for both vendors, Ive spent a good amount of money at both and always get 2 things. Very fast shipping and wonderful after purchase support.
There is plenty more that is mostly VG, but still has maybe tops 20% PG.
