Love this product better than the dyno. Gives me a clear focus on my 5am workouts. I stack with quadralean and cla. The taste is ehh but overall love the pump it gives.

This is really good and allows me to push through a two hour cardio session. I only take half a scoop to get me by. The flavor isn’t too good but I’m not using it for the taste.

This product does as described. I use it along with Amino focus, pump boost, and ReGen BCAA. One serving of this and pump boost before my workout. Then a serving on Amino focus and Regen bcaa while I work out. I've been able to pump out many new PR's. No one rep maxes but 15's and 20's. This stuff just makes you want to keep going. The flavor is ok. I have orange. It's not bad, but not good either. Over all I am super pleased with this product and will buy again

I recently gave this preworkout a try, and it's great!! It gives me the energy I need for working out in the wee hours in the morning, but it doesn't give me the jitters - due to not having as much caffeine as other products I've tried.

Jul 15, 2018

"Fast Fuel® Energy Matrix: 500mg ** L-Taurine, Caffeine Anhydrous, N-Acetyl L-Tyrosine" - as seen on the label 500mg of "Fast Fuel Enery matrix" and they dont even specify how much of each individual ingredient make up this "matrix". For all you know there could be 499mg of caffeine which is way over the recommended daily dose for an adult and can potentially cause serious problems. I used this preworkout when I first started lifting and at that time the label said 400mg of caffeine which is ridiculous nobody needs that its unsafe. The fact that the label doesn't clearly specify how much caffeine is contained in one scoop is criminal. I dont recommend buying this preworkout for this exact reason. I used it and it worked fine but no better than a pre workout such as C4 that only contains 150mg of caffeine and at least they clearly specify that on the label. None of this ******** "enery matrix" marketing ********. Be mindful of the amount of caffeine you are ingesting it can cause serious heart problems.

I really love this for my pre workout. Great energy and pumps without a crash. I wish would carry the Orange flavor as well as RSP bringing back the grape flavor. Thumbs up!

Overall, I like the product. No edge or jitters if used as directed. ;) My only complaint is the dissolve rate is very slow and requires a lot of mixing.
