I’m using 1.5% fa spearmint, 2.5% TPA cucumber, 2% INW melon, and .25% INW watermelon. I think fuzion might use a ‘sour’ flavor or maybe my percentages are just off, or maybe I’m using the wrong flavors entirely. This is by far my favorite juice, but I just can’t bring myself to buy anything for a dollar per mL. Thanks!
