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.

Don't waste your money . . .
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
