This pre is so strong that I don't even need a whole scoop. I feel focused and energized throughout my workout...and most of the time even until the evening because of how much caffeine is in it. The grape flavour literally tastes like a purple freezy, I love it! Green apple I could take it or leave it, tastes really sweet and artificial but not horrible. For those who are caffeine sensitive I recommend half a scoop (which is awesome because it'll last you twice as long).
