I picked up a 30ml of TFA Ry4 I really need a good recipe to use this... I have mixed up just a little.... and the flavor is just mediocre. Today hopefully I can place an order for a few more TFA flavorings..so need help in which I should get to add with the RY4. Ive heard Cotton Candy, Menthol, Vanilla....etc etc etc... Just need a good recipe to use this. I am only going to buy TFA flavorings, so please keep that in mind. If anyone has a good everyday vape using TFA flavors, please please let me know. %'s if possible, so I can replicate it. Also, I do like a powerful flavor. So far all my efforts I am only getting a hint of flavor. Ive used this in a Vivi Nova, and a AGA-T genesis.... taste is a little better in the genesis, but not much.
