I add enough water to equal about two gulps worth into a plastic kiddie cup. I add a little less than a scoopful of outlift and put top on (with small hole). Put finger on said hole and shake a few times quickly. Release finger when so the pressure doesn't pop off the cap. Drink the frothy brew and enjoy the strong tart flavor. Tastes just like sweet-tarts, has no bitter medicine taste at all. This product has the best flavor of all the pre workouts that I have tried. I just hope they don't mess with the ingredients like they did last spring without warning. At least it is still very enjoyable to drink.
