Need to mix something with no visible vapor

[G and C]

Make sure it's USP grade from Amazon. They've started selling some Kosher PG ad VG that suggest it's USP, but it's not labeled that way on the bottle you get. I've always ordered my Essential Depot PG and VG from Amazon with no problems.

Check out this thread.
Can I use this

Agreed, the only PG or VG that I use is Essential Depot with the USP label.
