Quality Ingredients
The fact that the measured ingredients are in the athletic-must ranges, and it ISN'T over caffeinated makes it a MUST try. It did not disappoint. Now, I don’t like Cherry or Kiwi, but I have had worse. Combined was humorously bad tasting For Me. You might like it. But in 15 minutes I was ready for my HIIT training and never crashed after. Give it a try and enjoy for sure.

    So Far It's the Best Pre-Workout I've Tried, I've had others, Been from Nasty Taste to Just plain Horrible, I started taking regular BULK, I liked it, my workouts were great, so I decided to try BLACK, Now this is a great pre workout!!! The taste is the best I've had among the others that I have taken and the results are obviously noticeable,, but not in a slap you upside your head way, you just don't want to leave the gym, I find myself sometimes looking for another exercise to preform, but i have to make myself leave once i get over two hours, I have not experienced any nasty after effects, no headaches, tummy aches, just pure clean workout energy. I love the stuff. If you see a flavor you like I suggest get it when you see it because it wont be there the next time you look, at least that happens to me, I like the Black Cherry and I'm trying the Cherry Kiwi in the next hour, I'll come back and let you know.

    This pre-workout is unlike any other caffeinated beverage i’ve ever consumed. The feeling isn’t that of a typical Pre Workout. Its visceral. It is the only pre-workout that gave me a legit high. Not from the supplement itself, but instead acted as a precursor, enhancing my workout, sauna routine, cold shower and overall stamina throughout the day.

    After using it all up, I decided that maybe the price point wasn't justified. I thought, maybe I could get the same thing from a normal, everyday pre-workout. It would take 3 different types/brands of pre for me to realize that this product is truly unmatched in its category

    I really do love the transparency, not so much the taste

    Flavor Name: Cherry Kiwi

    I have tried two different flavors so far and both have a bitter stevia aftertaste that is super overpowering. It's not undrinkable but it's not as delicious as Cherry Kiwi would have you believe (as a black coffee drinker I can tolerate some bitterness). I can tell there is some sweetness there that tastes good underneath the bitterness, so maybe if you don't experience the stevia aftertaste you will be in for a treat – I can't say for sure.

    What I do like is that the ingredient profile is actually pretty solid for a pre-workout, it's not just a ton of caffeine and low doses of unnecessary fillers. It does work to amp me up before a workout, although I like to add just a touch more citrulline to the mix. The transparent label is also extremely rare to see and something I think is worth pointing out (even the amount of flavoring is labeled in mg…when was the last time you saw that?).

    While the cost is higher than other pre-workouts I think the informed choice program adds a bit to the value here and gives me an even stronger sense of their commitment to offering a quality supplement and providing exactly what is on the label. If it wasn't for the bitter stevia aftertaste I could easily recommend it to anyone but I'd only consider it if you are someone who doesn't notice that.
