You want USP grade stuff, and it should be clearly labeled as such. Frequently USP grade is advertised as Kosher as well (and to make matters more confusing, also as "food grade") but that doesn't mean all Kosher or food grade VG/PG is also USP.
TL;DR: if it doesn't have USP on the label, avoid using it
My walmart carries USP VG in the pharmacy dept. been using it for months with growing any extra limbs.. I'd recommend it over this.
Wait, What? Wal Mart carries USP VG (At least your store does)? Could you provide the link from Wal Mart's website that shows what your Wal Mart sells?
Couldn't find the link on their site but found this thread on an ecig forum. The pink and white bottle is the one I have. (Sorry I'm on mobile)

I didn't read the thread and I'm sure there's going to be some "youz gonna die!!" comments but I've been using it for quite a while... Guy that got me into vaping used it for all my juice before I started making it myself.
So I did the math on the VG you get from Wal Mart, it would take 6 bottles to = one 1 Liter bottle from Freedom Smokes. My Wal Mart sells VG @ 3.99 for 177Ml for a total of close to 24 dollars. 1 liter from Freedom Smokes = about 18 dollars. Why not save money and buy from Freedom Smokes?? Just wondering is all.
KSA stands for Kosher Supervision of America indicating that it's 100% kosher. It's OK to use.
USP > KSA, by orders of magnitude. "Kosher", with reference to glycerine, just means it comes from vegetable sources. It means nothing about the purity of the product. USP means 99.7% pure with a maximum of 0.3% moisture, and very strict standards on impurities, in the parts per million.
Vegetable glycerine is produced via the transesterification of a triglyceride (vegetable oil) by an alcohol. For any food grade glycerine, this is done using ethanol. Purification of this includes carbon filtration to remove organic impurities, ion exchanges to remove salts, and multistep distillation. Contaminants most often include ethanol (which is fine), ethylated fatty acids, (which will coke on your vape and taste horrible), water (which will require higher power to vape), ethanol reactants from impurities in the oil (many of which are carcinogenic), chloride salts, and heavy metals (which can be present in the feedstock).
Short answer: don't do it. Kosher is a set of laws described by desert nomads in the prescientific days of humanity; USP is a science-based description of absolute purity. Vape only USP grade chemicals, or risk your health.
In depth, to say the least. Well, I'm glad I didn't vape it. I just cannot find USP VG anywhere around here.
Thanks :)
The big box drugstores (Walgreens, CVS) and Walmart all sell rebranded Humco glycerin; IMO it's not the best VG I've encountered but it is USP and it is vapeable :)
If you can find NOW glycerin (I get mine at a local Better Health store but hear Whole Foods also carries it) it's well worth a try.
> Kashrut(kosher) laws are Jewish religious dietary laws having to do with the preparation of food products and really have nothing to do with the labeled purity of the product. Also, Kashrut(kosher) laws are jurisdictional(handled differently in different places). In some cases a rabbi must come to the manufacturer and verify processes and equipment conform to kosher law and in some places it's enough that the manufacturer says or thinks he is conforming to the kosher laws. In any case USP and Kosher are 2 different things.
From this thread on ECF. I'd stick with USP glycerin.
If it is USP grade, is it required to be on the label?
