ok got a question, Is there anywhere that has a list of what grades of PG is used in what items? I'm just curious because both the USP and the Tech is 99.X% pure I think the last tech grade I looked at was 99.98% and the last USP I looked at was 99.5%...
Its kind of like my Tech grade lye is more pure then the food grade I can buy at the same place....
Thanks
