Best Pre-Workout That I have tried! ( It's Good)
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.

Original is better
USE TRANSPARENT LABS REGULAR PRE-WORKOUT! I have high caffeine tolerance but this blend just made my bpm sit around 150 during a hard workout and didn’t come down between sets and overall killed my performance at the gym with 1 or 2 scoops I tried both, but their orgininal formal works great lets me squeeze out a couple of more reps and lets me lift more, but the black pre workout made my heart beat out of my chest and didn’t help me lift heavier or for more reps I just felt like I was going to die.

Yum
The flavor is fantastic not too sweet but the formula is slightly different than the formula on Amazon there is 325mg caffeine from black coffee bean not the green coffee bean and there is no dicaffeine malate that would be making it 350mg total i still love it tho you dont need 350mg caffeine 325 is plenty and I couldve sworn it was 270mg the last tub I bought but flavor is on point with the cherry kiwi

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

Works as claimed!
I’ve tried a LOT of pre workouts. Including Insane Labs, which I am convinced uses crystal meth in its “proprietary blend”. This stuff is clean energy and doesn’t taste terrible.

Cherry Kiwi is much better
I like this flavor MUCH better than the Black cherry flavor (which tastes like cough syrup to me). Really appreciate the stevia so I can stay away from the artifical sugars like aspartame & sucralose that populate other brands.

Doesn’t Mix Well and Tastes Chalky
Have used a lot of preworkout over the years and this is not one of the better ones. Most immediately prior to this had been using Glaxon’s pre-workout but they went out of business. Saw this was highly rated in a bunch of online articles so thought I’d give it a try. First off, it doesn’t mix well. Even using 50% or more of the recommended amount of water to mix it with still wind up with a bunch of powder in the mixture. It doesn’t taste particularly good and because it doesn’t mix well is very chalky in texture. I didn’t notice any significant amount of energy or improvement in my workouts. If I drank the pre and then got delayed in starting my workout then would get tingles and antsy. Will not be buying again and will have to try and find a better pre.
