Most of them are PG. If they are TFA you can look on the flavor apprentice site and most of them will tell you for sure. Not sure about the other brands and how to find out for sure.
Thanks. I'm going to the web site and checking out the different concentrates that I have and marking them in my Android recipe app if they are TFA or something else and PG based or not.
