Ratings & Reviews
I have tried many different pre workouts from Labrada, ON, GNC, Cellucor, Performix, etc. I have found I really respond well to fast fuel. Great value for the money as well. Some of the pre's I've tried were the same price but did not even last a full month. Another great product from RSP!
I guess it might depend on the flavor, but to me, this product has a "medicinal" taste to it. (I am going to try a different flavor once my current supply runs out.) I also have noticed that it tends to cake, particularly on the bottom of the container and this despite the oxygen eater cards inserted into the product. Other than that, I definitely get a surge of energy. I take this about 30 minutes before training and it does what it promises. It doesn't cause jitters at all. I've also "experimented" a bit to see how it feels when I take this before a workout versus when I take a cup of coffee straight up. No comparison--Fast Fuel gives me better results.
My first time trying RSP and it's perfect! I take it before the gym and it gives me the kick I need to get through my workout and then some. The fruit punch flavor doesn't taste much like fruit punch, but it's still a good taste nonetheless and does it's job by giving you a perfect workout
In my fitness journey, I am always on the hunt for the best products that will aid me. After talking to a few brand ambassadors from RSP, I deduced to purchase some Fast Fuel. Taste wise, it's okay. Though, I felt like it was missing something flavor wise. Mixes extremely well and there was no chalky texture which is a plus. As far as what it supposed to do, it exceeded my expectations. I had a good amount of energy that didn't waiver during my training session. The pump was INSANE! At one point, I questioned if I could handle any more pump. Overall, it's a good product. I would have given it a 10 but the flavor caused me to give it an 8.
If you're looking for a pre-workout, this is not it. This gives absolutely no energy, and I even tried upping the dosage to two scoops. Treat this like BCAAs at the most
Definitely a great tasting pre that gives me enough energy so I can tackle my workouts without feeling like my heart is going to pop out of my chest.
Perfect amount of caffeine for a workout, worked better than most pre workouts I have tried. I highly recommend this product.
It was a good pre workout overall it gave me enough energy wake up to start my workout. It is great for someone sensitive to caffeine but I am very caffeine tolerant.
Fast Fuel is by far the best pre-workout supplement that I have taken over the past few years! Incredible flavor especially both fruit punch and blue razz. Both these flavors are excellent and easy to take. My good to flavor though, has to be fruit punch. I have never had a bad experience with fruit punch. With Fast Fuel, you get a great tasting product and the perfect amount of caffeine to kick start your workout! I suggest that everyone needs to give this pre-workout a try! Overall excellent products from RSP Nutrition!!
This stuff works amazing. Really recommend it.
