I have flavor arts and 4% would be way too high for me. I only use at 1-1.5% and it kind of gives off a rind or skin taste that may be a bit unpleasant. Honestly it's to realistic for my taste. Try in those percentages and whist to your palate.

I have FA Cucumber, and that shit is stupid strong. I tried it at 1% with some watermelon, and all I could taste was sweet cucumber skin. It also made my tank smell like cucumber for a month. I had to wash that tank with vodka and a fine brush. This flavor went into my 'never use again' pile along with FA Black Cherry. If someone twisted your arm to use it, either dilute it, or use it at 0.5% or less. Best of luck.

I have CAP Cucumber and I use it at 7% in a cucumber watermelon recipe and you can taste it, but it doesn't overpower the watermelon.

I'm running FA cucumber at 4% and really enjoying it. I have some other flavors toning it down tho
