Key Ingredients Benefits*



Red line graphic


Citrulline is a direct precursor for arginine and arginine is converted to nitric oxide (NO). Citrulline malate ingestion before resistance exercise can lead to better workout performance.*



Red line graphic

Carnosine is one of the most important acid buffering compounds in muscle cells. Regular Beta Alanine supplementation leads to accumulation of carnosine in muscle enhancing the buffering capacity during high intensity muscle action.* This supports gains in strength and training volume over time.*



Red line graphic

TeaCrine™ works to increase alertness and focus during exercise.* At 125mg, TeaCrine™ is able to work with caffeine to support cognitive benefits during exercise to Never Waste a Workout!*



Red line graphic

Arginase enzymes maintain lower levels of free arginine in the blood and tissue. Arginine can, in turn, support healthy blood flow to and within working muscle to aid workouts.* Blood flow supports the popular skeletal muscle “pump” felt during and after training.*



Red line graphic

Betaine (trimethyl glycine) is found in a variety plant sources, especially beets. Betaine serves in the building and recycling of key energy and other molecules as well as methionine.*



Red line graphic


Caffeine is one of the most commonly used stimulants among athletes. It provides stimulation of the central nervous system to support alertness and energy during a workout and can support strength for some during resistance exercise.*

Support Nutrients*


Red line graphic

Tyrosine is an amino acid and the acetylated form of tyrosine (N-Acetyl-L-Tyrosine) can increase stability. In addition to serving as a building block for protein, tyrosine is used to make key neurotransmitters in the brain, namely dopamine, norepinephrine and epinephrine. Serving as a precursor for key neurotransmitters acetyl-L-Tyrosine may support mental cognition during workouts.*


Red line graphic

Taurine is an amino acid which is not used to make protein. (non-proteogenic) Taurine is one of the most abundant free amino acids in the CNS. Taurine may support CNS activity during exercise.*


Red line graphic

B- vitamins support energy systems at rest and during exercise.* Folate and Vitamin B12 play a role in methionine recycling and Methionine is a critical amino acid in production of all proteins.

Coconut water / Fruit Powder

Red line graphic

Extract from the exotic coconut fruit.

Got the Chilled Fruit Fusion as a sample. It was awful! Didn't mix well and I had to take a min after drinking it to make sure I was going to keep it down. The pre-work out ***** was fine but the flavor was terrible.

This is the best prework I have ever used. When I want to push super hard I use a full scoop and usually make a new pr. It lasts at least my hour and a half workout. When I just want a good pump and energy I take 2/3 to 3/4 scoop. Never a crash. Start with half a scoop and work up. I use another pre every other day (lighter days) so it never stops being beneficial.

Good energy and really, really good pumps with no crash. I think a lot of the negative reviews are because people just don't have a F** clue what they're doing. The potency of this product is very strong. I am very sensitive to caffeine, but I have no issues because I only take a 1/2 scoop. I may do 3/4 scoop on occasion. I really think a full scoop is overkill. Sometimes less is more. Know your body and listen to it.

I got this as a sample that came with a product that I had ordered from here and lemme tell you......this gave me the jitters and made me feel so UNCOMFORTABLE that eventually went away but nonetheless this product is NOT for me. Flavor is decent but I will stick with what I USUALLY take rather than this CRAP!! Buyer BEWARE!!

The price is too high. The market offers much cheaper and better products.

I got to try Cherry Watermelon flavor. I like the kick and the pump that Dymatize Pre W.O. gives. The old version of this pre would clump up and make it nearly unusable, but this version of the preworkout, there is no longer any clumping! The flavor was ok, I definitely could tell that I was drinking cherry watermelon. No chemical aftertaste, but it is not my favorite flavor. Great preworkout overall. It does not have anything exotic that anyone needs to worry about like some preworkouts and works great.

I received this as a sample and tried it. It is the most horrible tasting product I have used. It did not dissolve completely and it gave a burning sensation for a few hours after use. It did give the boast to energy for the work out but the burning and itchy feeling was the worst.

I first tried this product a year and a half ago in the cherry limeade flavor. It was a horrible experience for me. I was not a fan of the extremely tart and bitter flavor. Additionally, I experienced lots of tingling in my body and headaches. I believe these occurrences happened due to the amount of caffeine in the product. I'm sensitive to caffeine in general and often refrain from teas and coffees. Usually, for a pre-workout, I'd just use creatine. But I received this product as a sample, so gave it a whirl. It was unpleasant. Fast forward 18 months later, and I receive another sample, but in a different flavor. This time it was orange-pineapple crush. I'm not sure if the caffeine amount from 2017 was lowered or not, but the second time around was more favorable. I did not experience the tingle or head pain but did experience body heat. I felt a constant burning sensation throughout my body for about 30 solid minutes. This did not impede my ability to work out, however. Yet it was very noticeable. What I loved about the product was that not only did it push me through my stretching and warm up with a huge energy boost; it also sustained said energy and focus to complete my full workout at a faster rate than I normally would. What I disliked was the burning-again, the feeling eventually wore off, but it would be great if it didn't have it at all. Perhaps Dymatize could make a caffeine-free version in the future? I also didn't like the flavor mashup. I understand supplement companies are trying to be unique with blends. But I rather save the surprises for the Whey Protein shakes as a reward. For pre and intra workout drinks, I want the endurance and energy to push through. I don't want to be distracted by exotic flavors on my palette taking me off my game during my workout. Go simpler for the flavors next time. If those particulars aren't important to you and you're considering this product, absolutely try it. It's great (my rant aside). :)

This is one of the best (if not the best) pre-workouts I’ve had in 12 years of taking such supplements. I’ve been alternating this product with other products for a year to avoid becoming completely used to it. It’s not over the top as far as energy but there are no jitters and the teacrine provides a noticeable boost in focus and mood. Skin tingle is definitely present but subtle without feeling like a reaction of some kind. Cotton candy is too sweet for me but other flavors are palatable. Even if this product doesn’t fully dissolve every time I don’t see it as a reason to lower the rating to an 8- the people who complain about that probably wear lifting gloves.

Pre workout gives awesome boost. One of the best ones I've tried in a while. The only down side to this pre is that it does not dissolve well. The company spent a lot of time on the energy effects, but failed to properly get the product to dissolve. I will keep using the pre due to the actual results in the gym. It will not be the only pre I use though.

Product worked well in all aspects that it claims but after a couple days I started breaking out really bad, I've never taken anything that made my back break out like this and it took me sometime to figure out what the problem was. After several weeks I finally narrowed it down to either this or another supplement and turns out I'm still taking the other and the breakouts are gone but scaring is not. There must be something in it that I was reacting to. Now taking another Pre workout and all is better.
