Is this glycerin ok to use? It says that it is usp on the cvs website, but it does not say usp on the bottle from the store it just says "pure glycerin". I mixed 50/50 with my liquid and it seems fine, just more clouds and less throat hit. The cvs website says it is "pure glycerin usp" and it has the same sku # as the website. Does anyone else use this?
