Bulk Apothecary sent me a bottle of 100% pure PG. Nowhere does it say USP on the bottle. The VG I received says USP on the bottle. Here's what they sent...Pure Propylene Glycol | Nature's Oil
Is This Propylene Glycol Ok To Use

I wouldn't.
Send them an email and ask if they have USP PG. If they claim the stuff then sent is USP ask them why it wasn't labeled as such.

This is the actual product I ordered and it states it is USP PG Wholesale Propylene Glycol in Bulk...Cheapest USP Propylene Glycol Online So I don't know what affiliation they have with Natures Oil
Natures Oil and Bulk Apothecary are one in the same. Natures Oil is their branded products division. Official link below confirming this.
About Us
That said, most of their products are for soap & lotion making and are of good quality. They are advertised as USP Grade, though it may not be on the label. They may be overlooking it, or they may simply not add it to their product labeling, but the only way to know for sure 100% would be to get in touch with them directly.

I just got off the phone with CS and they assured me it was USP grade. The lady claims they sell in bulk to many ecig vendors and juice makers.
Man, that is a heck of a lot of PG.
I ordered a quart of PG and a quart of VG 2 years ago and still haven't used it all.

Water has a density of about 1 gm/ml (at standard temperature and pressure), so 1 pound would be about 15.33 fluid oz.
PG is a little denser (@1.04gm/ml), so 1 pound of PG would be about 14.74 fluid oz
VG (@1.26gm/ml) is a little denser yet, so 1 pound of VG would be about 12.17 fluid oz.
For quick and dirty calculations, I remember from high school chemistry (many years ago - but it stuck with me) that when figuring the weight of water that "A pint's a pound the world around!"
A pint of water is around a pound and a gallon is around 8 pounds.

16 ounces = 1 pound but volume is measured differently so I'm not sure what you're asking. 16 ounces of water equals 1 pint. VG is a little heavier than water so it should be a little less than 1 pint.
