I don't recommend Blueberry Extra as a standalone or omitting Blueberry Wild in this recipe. Although good right away, After about a week the creams come together very nicely with the blueberry. This is by far the best Blueberries & Cream I've mixed to date. Enjoy! :)
Edit**** Super Sweet is an optional addition if you like your Eliquid sweet. To avoid coil gunking I personally like not using it, But this is of course up to your preference. :)
Modified the OP's recipe as it needed fixing to my liking. If you like a creamy blueberry poptart tasting flavor, then this is it. Recommendations always welcomed for improvement :) enjoy
