Kathy123....I'm no expert by any means but have learned alot from the friendly folks here. I went to a Pharmacy today that had na compound mixing lab and bought 473ml(1 pint) og USP Propylene Glycol for $10.50. WOW! They are going to order me some Vegatable Glycerin for about the same cost. Here are a few sites that Hoosier was so kind to mention: xtremevaping

I do think the VG has a sweeter taste....guess thats why they put it in gummy bears. I like to mix the two myself. Hopes this helps!.........JB
