USP
As long as the two are together on the label, it meets the pharmacopoeia standard. Anything else on the label is marketing and liability notices.
My friend pays extra for his because once it's opened, whatever is not used is disposed of so small bottles with lot numbers that peel off for records is what he's getting. (He owns pharmacies now so doesn't do much compounding nowadays, but his pharmacies specialize in compounding and he started from scratch.)
My first big PG purchase was labeled for livestock use only from TS. It was USP. I've dealt with standards of a wide variety for quite awhile in my professional life. USP was new to me so I discussed it with Greg (my pharmacy friend). USP isn't much different than any other standard I've dealt with, just enforced by a different government agency is what I found out from Greg and my own research. Standards have a nearly mythical aspect to them until you're hip-deep in them. So I scoff at UL certs. Know an HS-10 AASHTO structure is probably actually HS-20, but not HS-15. Just because it meets APEX standards it may not be right for your specific potentially explosive environment. Ballistic ratings are nothing like what most people expect.
USP PG and VG seem to be very misunderstood. But even people who deal with AASHTO standards all the time seldom actually understand what they mean, so it's understandable.
I'm still amused by it all. I usually wonder why the folks that claim the additions of marketing or Kosher on the label make something less USP don't go for reagent purity which can be higher that mere USP.
Glycerin is a medicine used to get bowels moving. And that labeling may spook some folks too.
In case anyone is wondering, the difference between a ROHS compliant gizmo and one that is not compliant could be a single screw with the wrong rust resistant coating. And it's a crappy job being the guy who has to track all that down and document it to gain ROHS added to the label. That was a short-term contract thankfully. I had more fun working on an Eli Lilly project, but they won't let me talk about that and the FBI is the enforcer on that NDA, so I can say it was fun and really cool, but only a couple dozen people and will ever see my work there and can never say what I designed for them.
(Now you know more about Hoosier than you probably wanted to know.)

I found what I wanted Glycerine, USP 
--- you know I may be paranoid (not may be ---am) but that's what I wanted. I see so much crap mis-labelled and stuff that I feel much better having it exactly the way it is listed in USP and am a happy camper.

I thought you hinted at that I was wrong stating that USP isn't self-enforced but enforced by the fda in the states by law for pharmaceuticals, and since vg/pg we use are simply stuff e.g. gotten from healthfood stores etc. then they can of course test for usp compliance and label it on there bottles, but dosen't have to label it in any specific way, as opposed to others defined in I believe food,drug and cosmetic act or whatever... I mean instead of USP over, under or next of product name, then ten lines down etc. I remember reading parts of that act, allthough it was for canada, but whatever, that e.g. healthfood or what they called it, was recommended to follow same labeling, to avoid medication errors or something...
Second, @All, allthough off-topic, I have to seriously apologize for my spelling! I'm not very good as spelling english, but will now install a spell checker if I can find one for my dwb linux browser. However, whats worse, is that I forgot to close down the lid of my laptop some time ago when I went to sleep, and then my cat has walked over the desktop, so some buttons dosen't react so much anymore, and I tend to forget to recheck my posts before submitting! Sorry!
Edit: aspell-en freshly installed on my arch linux box... Promise to improve from now on!

@mhertz- I and about ~95% of Americans can just barely speak one language. Don't worry yourself to much how well you spell your second language
