As mentioned, these as stand alone,some will be bleh....i can see juicy peach being best solo out of these....need some creams and sweetener to improve or blending with other complimentary flavors to round things out(think of some of these flavors as building blocks, put together to work better...some not all) Cool of you to test solo though, gives a good idea of individual flavor tastes, but many from tfa do need some supports...many other companies out there to try that may provide a better flavor for you too(ex...took many orders to find my raspberry I wanted, not tfa)...trial and error part of diy to Hone in on what you want specifically, good luck with your diy!
