I DIY and buy premade from several USA vendors.
I prefer 100% VG eliquids...I have to know that I'm getting no more than up to 20% PG, so if a vendor doesn't disclose, I'm afraid to order and/or go make my own

Some vendors that I've tried for some good eliquids, I'll name Heather's Heavenly Vapes because I can get 100% VG and they are full of flavor, but most need to age a week or more before the flavors develop, as with most juices IMO.
Other's would include: Vapors-Choice, Good Prophets, Orb Vapor, Virgin Vapors, Alien Visions, Highbrow, HighDesertVapes,
