I'm usually pretty resourceful but holy crap USP grade PG is hard to find!! So far the closest I have come is a "Propylene Glycol - Oral Solution" Veterinary Use Only - From an agricultural / livestock store .. The label doesn't say USP anywhere on it so I am not going to chance that .... .. PLUS, it lists Choline Chloride, Potassium Iodide and Cobalt Sulfate among the active ingredients .. No literature (Tech. Specs, MSDS, etc) I can find on PG lists these nasty ....ers anywhere. No Thanks !!
I have also found one large company that distributes PG USP but will not sell privately and the compounding pharmacies I've contacted will not sell it either.
.... Why is this stuff so hard to find?
