Review of WS-23 Flavor:

Like Dave M, this is that something I've been looking for for years! I've tried all the menthiools, mints, and other additives just hoping one day to find an additive that gives me that true cooling, menthol hit. I usually use this at 1% for cooling, 2% to increase the TH , just an extra bonus to this produces! Buy it, Try it, and be happy you finally found the answer!
