Review on 🔒 Certified Kosher Propylene Glycol: High-Quality Grade for Various Applications by Kenny Sarma

It used to be very valuable as a base liquid for mixing your own vape juice. But they keep increasing the price so I started buying another brand from another website because frankly PG is PG. As long as it is all GRAS/Kosher/USP there is no difference in purity or quality from one manufacturer to another. If the quality was low, the PG would be colored and it would be obvious that it had impurities and the like. So save your money and get the cheapest food grade USP PG you can find.
