I'm not sure if it is my place to ask. But the whole reason why I want to get into DIY is to save money. But honestly, even with recipes, I haven't found any flavorings yet that can really beat the brands. Brands like Epic juice, Halcyon, and Fuzion Vapor. I know that Fuzion uses TPA, but even so, I can't imagine something like that coming from a blend of TFA flavoring. So what do the "real" companies use for flavoring? Do they make their own (that would be too difficult)? Even though I can make my own juice, I still find myself buying juice too often.
