For those of you that are interested in smaller quanitities (one gallon or more) of glycerin (USP Grade Glycerin - 99.5% Vegetable Based, the gallon that I ordered said it is 99.7% USP) can order it from https://www.usglycerin.com/USGLYCERIN/ .
LOL, what a coincidence that you just brought up compounding pharmacies here, and I just did too, but in a slightly different context, here:

Omigod, and posted at the exact same time!
Lorraine, PG is not as sweet as glycerine. I don't detect soapy either, but who knows how our tastes might differ.
Hey hobson!
I didn't see your name in the Texas Group. PM Lika and ask him about joining Tejas Vapin. We have over 60 people in Texas. Lika is the only one who can add new mwmbers.
Hope to see ya there.
Cheers;

Glycerine can also be extracted from animal fat. I use only 100% vegetable glycerine, seems safer to me. I believe the Now brand is made from coconuts but I know it is 100% vegetable based. It is rated for topical and internal use. Most of the other glycerines I have seen that do not state 100% vegetable based say only for topical (external) use. Like the Walmart/Walgreens stuff. I bet it has animal fat in it. I am not vaping that sheot.
where do you get your vg, then? Thanks in advance.

NOW brand is available in health food stores.
Jim, it sounds like you are thinking that there is some diference between VG and glycerine. But there isn't, really. Vegetable glycerine may have a different route to the shelf than a glycerine that doesn't carry the "vegetable" in its name, but by the time it's bottled and sold, it's the same thing.
Glycerine is also sometimes called glycerol, and sometimes even spelled glycerin, but all four terms are 100% interchangeable for our purposes, so long as the grade remains constant (USP grade here in the US, or BP grade in the UK for the best assurance of purity).
Nuck, and I've seen the claim that VG is more sticky than G.
Yes, vegetable glycerin is derived from vegetable fats, and glycerin/glycerol without the "vegetable" in it's name may be derived from animal fats. That's why I acknowledged that they may have a different route to the sales shelf in my post. But the bottom line is this: The resulting chemical compound, no matter what it is called, is C3H5(OH)3.
Could it be that the 1% or up to 5% impurity makes enough of a difference for people to detect a difference between brands? I don't know. But I do know that if the chemical compund is the same, what you got is the same. So unless someone is a vegan, or has other similar reasons to avoid anything made from animal fat, there is no difference, for ecig purposes, between vegetable glycerin, glycerin, glycerine, or glycerol.

Two brands of VG, both USP/food grade can differ because of the amount of water they contain. Even a slight difference in water content (1 or 2%) can make a marked difference in viscosity.
