@susieqz - I like and use TFA Peach and/or TFA DX Juicy Peach (has no ethyl alcohol that the regular Juicy Peach has in it), in eliquid recipes that I make for myself and a few other people. IMO, they're both good tasting "peachy" flavorings, when used at approx. 5-7%
in a recipe, along with other flavorings. However, I don't know of any Peach flavoring that's good as a single flavor in an eliquid. Most all eliquids require the use of some blenders (creams or similar flavorings), and fairly often an additive or 2 (sweetener, coolant, nutty tasting flavoring, etc.) to make a good tasting eliquid.
The exception to that could be a Peachy flavored "One Shot" that you might be able to find. That would be an already mixed bottle of flavorings (peach and others)...that you would use by itself...added to your own VG, PG, and nic base.
