Decided to take the plunge into DIY today. My local B&M has an EZ DIY premix, so I bought 120mL of 9mg premix. I already have some PG and VG here at home, although I don't much use the PG. I only bought a few flavors, figuring they're only $3 for 6mL, so I can go back for more once I get use to mixing. I ended up with Strawberry, Blueberry, Cherry Cola, Bavarian Cream, and Vanilla Cream. I also bought a bottle of sweetener, a couple of syringes, and a few 10mL bottles. I was told that with their DIY premix to use about 12% flavoring to 88% base. I downloaded the ejuice-me-up and have been playing with that a bit, plus the one on Steam Engine. Is there a calculator for the iPhone by chance? Also, does anyone make a straight 'flavor sample?' By that, I mean, using VG and flavor just to see what the flavor is like. Any suggestions? I'm totally open to suggestions.
