You are better off buying VG and PG separately if you are planning on making flavored
eliquids, which is what I'm going to assume you will want to do. The reason being is that the flavors you add may be PG based which will change your overall percentage of PG/VG, and your nic base will also change it. And you most likely will like trying several recipes with different percentages of flavoring added, which will also make your PG/VG vary. It's just way easier to have both separate so you can fine tune it all easier once you know what all you want to add. You can still use up what you bought already though, but you will probably need to buy VG and PG separately still to add to it as you go.
