Here's a hint. Choose a recipe or two from the VU recipe forum or ELR or All the Flavors that sound good to you. Just buy the flavors to make those recipes and mix them at the indicated percentages. There are numerous DIY calculators around that you can use to tell you how much of each flavor to add. The calculators on ELR or All the Flavor are good ones. If you use a Windows PC ejuice me up is a good stand alone calculator. The calculators will tell you how much nic, pg, vg, and each flavor to put in for the size you want to make.
