Needed some VG so I picked this up is it safe?

I was wrong. I was reading to much into the part of the sticky that said "It is possible that a USP product can either be pharma grade or food grade. The USP designation only refers to a general production regime and does not cover the exact contaminants as long as the minimum standard is met". My apologies to any alarm I may have caused if any.

I've read that before, but that's the only place I've ever heard any implications that USP might not necessarily mean pharma grade. I think maybe it is poorly worded, or perhaps even just plain wrong.
