Guys are we talking pharma grade - not food grade or organic - pharma grade is very pure (least impurities) , most often synthetic
Yes USP/pharmaceutical grade. You may want to check out the many threads in DIY about glycerin and PG if your needing more information. The best one is- http://www.e-cigarette-forum.com/forum/diy-e-liquid/277267-purity-pg-vg-peg-short-version.html
edit to add:
Most of what is sold is VG, vegetable glycerin and soy based. It is a by product of fuel production if I recall correctly.

been making my own juice as close to 100% VG as possible for awhile ... USP pharma grade - thats certifiable - is the best of VG you could vape - food grade is more for ingestion than inhalation.
all the sites im finding on the web list usp as pharma grade. 99.5% or higher.
and many of the sites selling it also state they add purified water for consistency and workability to pharma grade.
i think you may be paying much higher prices for something thats not very different in purity levels..

High Desert Vapes stocks WL nic/PG/VG and has VG in stock as I'm typing this, just ordered another bottle along with VG-base nicotine.
Yep, the stuff I got from Wal-Mart to start with is pharma-grade 99.5%, it's over in the pharmacy area, under skincare or balms I believe.
i know the MSDS and cert of analysis from essential depot state it tests at 99.7% or higher pure glycerine
so i think maybe the pharma label is an easy markup for some companies..
I know im not going to sweat it when the impurities are listed in the 10 parts per million range lol

About USP
About USP header
The U.S. Pharmacopeial Convention (USP) is a scientific nonprofit organization that sets standards for the identity, strength, quality, and purity of medicines, food ingredients, and dietary supplements manufactured, distributed and consumed worldwide. USPs drug standards are enforceable in the United States by the Food and Drug Administration, and these standards are developed and relied upon in more than 140 countries.
USP standards are developed and revised by more than 900 volunteer experts, including international participants, who work with USP under strict conflict-of-interest rules. Since its founding in 1820, USP has helped secure the quality of the American drug supply. Building on that legacy, USP today works with scientists, practitioners, and regulators of many nations to help protect public health worldwide.

I want to make sure to handle a possible confusion between USP (pharmacopoeia) organization and pharmaceutical grade VG or what have you. Most people are selling USP food grade - NOT pharmaceutical grade which would be a purer - less toxins (impurities) - substance
Certificate of Analysis
The Good Manufacturing Practices (GMP) Certificate of Analysis shows the content and purity of a pharmaceutical product. When a product is accompanied by such a certificate, it has an exact quantity of active and non-active compounds, and is made according to standardized levels of purity.
Read more: GMP Certificate of Analysis | eHow
Good manufacturing practices for each pharmaceutical product in the United States are provided by the U.S. Pharmacopeia (USP) in form of monographs. The Food and Drug Administration (FDA), the International Standardization Organization, and scientists from other institutions are creating and perfecting GMPs for new and old products. Sometimes the monographs change, as research and purity requirements change, thus the old GMP is replaced by current GMP's (cGMPs).
Certificate of Analysis
The certificate of analysis ensures content and purity of a product
The certificate of analysis goes beyond the assurance label of USP, as it offers additional information on how the product was made and what it contains, according to methods of analysis which are standardized.
Essentials Depot has a COA for every product. So does Wizard Labs.

You can purchase Glycerin USP (USP is pharma grade) in 6 oz (177 ml) bottles at any local drug store in the USA. It is made by Humco and is labeled with whatever store brand name the store wants on it.
Here is an example. I buy two of these for $10 (no shipping charge!) at the local drug store. They have an expiration date that is about five years later than the bottling date, not a one year expiration date. These have the same USP grade as a 55 gallon factory drum of Glycerin USP. These are factory sealed bottles that have not been repackaged in open air which would reduce the shelf life to one year.
Once these bottles are opened, use within one year. Sealed, store it up to five years away from direct light and without refrigeration.

I read that post by rolygate a while ago, and I remember wondering about the distinction between usp food grade and usp pharma grade. I can't find any support anywhere for that distinction (doesn't mean there is no difference, I just haven't been able to find any reference to one). Several glycerin manufacturers websites I looked at stated that usp IS pharma grade. Also, roly states that usp doesn't state percentage of contaminants allowed, but other references I am reading says that usp does specify percent purity guidelines. In fact, if you look at the usp monograph for glycerin, it states percent of glycerin right at the beginning, and later lists percentages of specific contaminants allowed.
Glycerin Monograph | U.S. Pharmacopeial Convention
I go with usp grade myself. If I can find some sort of legitimate documentation that usp pharma is significantly different from usp food grade, I'd consider changing.

Hi richieducati,
The Rolygate link is confusing - I know it confused me for a long time
DOW PuraGuard USP/EP (PG USP/EP) | Dow Propylene Glycols
This link is Dow PG, but it may help your understanding of the "marketing". In this case, the same PG (Dow Puraguard 99.8%) is marketed in four different "grades".
What your looking for is the USP. And the purity starts at 99.5% and goes up.
Amazon.com: Vegetable Glycerine Kosher USP - 1 Gallon (128 oz.): Health & Personal Care
Amazon also has Essential Depot which many like.
Or you can get good quality at RTSVAPES or WIZARD LABS.
100% Pure USP Vegetable Glycerin: Food Grade VG Liquid | Buy Vegetable Glycerin
Good luck
Glycerin USP is pharmaceutical grade glycerin and the highest purity grade of glycerin sold in the US. The "purity" percentage for USP grade is 99.5% but many manufacturers (like Humco) produce a 99.7% product. They do this to meet the 99.5% USP specification with a little safety factor over the required minimal specification.
The .3% is water.
Once a factory sealed container of Glycerin USP is opened in open air it no longer meets USP specification.
Once exposed to air the glycerin should be used within a year to 18 months if stored without refrigeration. If you store it in a freezer then it will keep for years.

Pretty much sums up my research to date as well... based on reading the same article some time back. But I will dog it out and find out if there is a real difference between USP food grade and Pharma grade. I been vaping food grade - and sometimes organic food grade which is equally as easy and cheap to get. Food grade VG is the primary substance by far I am inhaling so it would be nice to know if there is a purer form. The other big area is what "heat" does to the mix, the metal etc. Specially with sub ohming which is where my sweet spot lies. Doing a bunch of research there as well - ( not worried about oxidizing wick) - concern would be about temp at the coil which if one is vapping at 1 ohm or less - is hot - real hot and the real reason so many are melting their center post insulators on RBA's in my humble opinion.
