Review on 🍃 100% Pure Vegetable Glycerin (USP Grade-Kosher) - Nature's Oil - 10 lbs (Gallon) by Doris Tran

I use VG for vaping. I've been blending my own juices since 2007 when vaping first started. The quality of the VG and PG is very important, otherwise I start coughing. My starting point is the main VG and PG depots. Their quality is top-notch, although their prices are higher. VG should taste sweet and have no aftertaste other than sweetness. If you feel bitterness behind the sweetness, don't use it for vaping. This VG is sweet, but I get a slight aftertaste mixed with sweetness, making me think it's not USPS food grade. On the other hand, I don't cough, which tells me I can vape.
