This is a well thought out combination of ingredients that play very well together. I got a really nice pump from this formula but the mental clarity and focus were the dominant drivers here. I got a really nice sense of euphoria and focus shortly after taking this and it lasted with me for hours after my workout was over. If you are curious about how the ProGBB and Yohimbines feel, they aren’t overpowering and for me, I didn’t feel like they made me feel uncomfortable in any way. Yes this ends up being a “sweaty” pre-workout for me but again, not to the point of feeling anything negative. The flavor I used was the Blackberry Lemonade which was very good as well. Taste is not high on my list of “needs” but when a pre-workout tastes good, it’s such a nice added bonus. Worth noting is the amount of caffeine per 2 scoops which is 500mg total yield. Even at this amount, everything just comes together quite nicely and very smoothly for an excellent experience.
