The Ultimate Pre-Workout

The word "ultimate" gets tossed around a lot these days. People love to claim they've created the ultimate training method, diet, or supplement, often without substantial evidence to support such bold statements. So what makes C4 Ultimate worthy of its name? How do we back up the word "Ultimate" to ensure this is the strongest, most effective, most powerful pre-workout on the market?*

Take a look at the key factors
that make C4 Ultimate.

Powerful Key Ingredients

Ultimate Energy

Caffeine (300mg)

Caffeine is a well-studied stimulant that has numerous energy, performance, and even fat-loss benefits.*


Tetramethyluric acid, or theacrine, is an alkaloid structurally similar to caffeine. Preliminary human study results suggest that the body doesn't adapt to TeaCrine as quickly as it does to caffeine, therefore prolonging tolerance.*


This plant extract may act similarly to yohimbine, and its effects are amplified when paired with caffeine.*

Ultimate Pumps

Citrulline malate (6g)

A precursor to arginine and nitric oxide production, 6 grams of citrulline may support an increase in nitric oxide levels. It supports the ultimate pump, especially when paired with arginine. Note that 6 grams is the entire scoop size of some pre-workouts. In C4 Ultimate, it's just the pump foundation.*

NO3-T creatine nitrate (1.5g)

A university-studied form of creatine formed when creatine is bonded with nitrate anions. On the individual level, Creatine and nitrate are powerhouse elements, but when fused together, they create an unstoppable bond.


Shown to significantly increase arginine and nitric oxide levels for up to 3 hours.*

Arginine AKG

Precursor to nitric oxide that promotes nitric oxide production in the body.*

Ultimate Performance

CarnoSyn beta-alanine (3.2g)

A full, clinical dose of this patented form of beta-alanine supports muscular endurance. Beta-alanine can sometimes produce a harmless skin-tingling sensation.*

Betaine anhydrous (1.5g)

Helps maintain cellular electrolyte balance and promotes hydration.*

Ultimate Focus

AlphaSize A-GPC

Supports an increased mind-muscle connection in the gym.*


Supports positive mood and cognitive function.*

Huperzine A

A nootropic that may support memory, learning, and concentration.*

Taurine (1g)

Helps support mental performance when paired with caffeine and B vitamins.*

A Legacy of Excellence

We've been pioneering, building, and perfecting pre-workouts longer than most brands have been in sports nutrition. For nearly a decade, the C4 family has led the pre-workout category with explosive energy and performance, the best flavors, clinically studied ingredients, and cutting-edge formulas.*

We're obsessed with research, improvement, and results. We're innovators and leaders, and we're not new to our work. We have a legacy of building the best, most effective pre-workouts available.

We can comfortably say, without a doubt, that the C4 Ultimate line is the strongest series of pre-workouts we've ever created.*

C4 Ultimate is the culmination of a decade of hands-on work in the pre-workout space. We're not talking about building a product in a matter of months. C4 Ultimate combines everything we've learned over years of study and real-world product development to deliver energy you can feel, powerful pumps, muscular endurance, extreme focus, and peak performance. Consider C4 Ultimate a masterpiece from pre-workout craftsmen.*

Clinically Studied,
Patented Ingredients

No matter how big the scoop size or how revolutionary it claims to be, a great pre-workout starts with best-in-class ingredients used in effective doses. Since ingredients are not created equal, patented ingredients are important for multiple reasons, particularly because they're backed by quality manufacturers who rigorously test and research their products to ensure efficacy and safety.

Patented ingredients are the best in their categories, or they're so novel that they're complete category-creators. We're proud to say that C4 Ultimate contains six patented ingredients from leading ingredient companies of the highest caliber:

The Ultimate Formula

C4 Ultimate Container

Creating the perfect pre-workout for people who demand nothing less than the best from themselves and their supplements has been no easy task. It's taken us years of work, the best ingredients from around the globe, and a consistent commitment to innovation, formulation, and product development.

We're proud to say that the formula powering each serving of C4 Ultimate delivers an ultimate experience on every level: the ultimate in energy, pumps, endurance, performance, and focus. This is not a pre-workout for the weak for weekend warrior. C4 Ultimate has been engineered for athletes, lifers, and lifters who aren’t afraid to work, sweat, and hustle for their next best.*

The C4 Ultimate formula delivers the explosive energy and performance you love from C4, plus a powerful combination of nootropics, mood enhancers, pump amplifiers, and endurance support to push you to your ultimate limit.*

The Cellucor Difference

Every tub of C4 Ultimate is the result of rigorous testing and research to ensure you get the highest-quality product possible, without compromise.

Our commitment to the following areas makes Cellucor stand above the pack:


We put every flavor of C4 through 100s of flavor tests. Seriously. And we don't settle. If a flavor doesn't measure up, we move on. We're dedicated to making the industry's best-tasting products, and nothing less will do.


We utilize an industry-leading evaluation method when working with ingredient suppliers, and we conduct additional stability testing on our raw ingredients to make sure our formulas have great physical stability. We also visit our key ingredient suppliers directly so we know exactly what we're putting in products, and we're very selective about working with only the best partners. (The same is true with our packaging.)

Product Development

Our in-house product development team has years of research and expertise, and a true passion for sports nutrition. We don't rely on a single person's opinion to build product. We have a team of world-class formulators who evaluate, debate, and discuss the latest research before we even put a formula down on paper. Add our incredible relationships with the world's best ingredient manufacturers, internal testing, athlete feedback, and years of leading the industry, and you get a development process that's second to none.

Commitment to Customers

We're committed to your results. At the end of the day, C4 Ultimate is your product. If you don't like it for any reason, we'll gladly refund or replace it. We're here for you.

Amazing pre workout but the new version (clear evolution or whatever) is way better, and don’t know why you guys are selling this old version rather than that new one?

I received a tub of the C4 Ultimate CLEAR in the strawberry watermelon flavor from a promo win. The clear version has no dyes, no artificial flavors,and has ALL the ingredients listed with no prop blends. After using it 6x in the past 3 weeks where I used it in between other pre's this is my final thoughts on it. The powder mixes very well with just a little foam that settles very quickly and just a bit of sediment on the bottom of the shaker cup. The flavor in 12oz of water has a slight strawberry flavor at first but then the watermelon flavor takes over so I would say it's a 30% strawberry 70% watermelon and sipping on it you kind of get a jolly rancher type flavor. I honestly don't think anyone is gonna have an issue with the flavor cause I found it easy to drink and enjoyable each time I used it and it's not overly sweet. The energy kicks in about 20 min after consuming it and for me it was very smooth and I would say it lasted about 90min before I felt it taper off. This has 1mg of Alpha Yohimbine and I feel that this is the key ingredient in the stimulants added that really helps give this PW it's kick and without it I think it wouldn't do much on the energy. The energy from this version is good and 1scoop is all you need as opposed to the other versions in the yellow tubs where 2 scoops are needed. If your slightly sensitive to yohimbine I don't think you'll have an issue with the 1 mg in this formula. The focus factor for me was pretty weak and I honestly never really felt much focus from ANY version of C4 that I've used in the past so for me the energy definitely out shines the focus. Pumps on this version are pretty good where you'll get hard vascular pumps and if your in shape your muscles will definitely have more pop to them as you train. The pumps aren't big puffy swollen pumps cause there is no glycerol in this formula so if that's what you want then you'll need to add at least 2 gm of glycerol to experience those types of pumps but on it's own it delivers pretty good pumps. Overall I would say this is a pretty good PW where I liked it for certain body such as arms, shoulders, and pecs and it's a good conventional PW to through in between using more heavier stimulant based pre's so that you give your body a rest from the heavy stimulants. If your someone who is use to using exotic stimulants each time you train then I honestly feel you won't feel the effects of this one and if your someone who uses the regular version of C4 and it's not hitting well in the stimulant dept then I would strongly suggest trying C4 Ultimate cause with this one 1 scoop is all you need and the effects are stronger than the regular version of C4.

Orang Mango is easily the best tasting pre-workout I've ever had. Icy Blue Razz is also good but is VERY blue, just dont be surprised if things (inside and out) change color

  • 6 Sour Batch Bros

Looking for a break from exotic stims (DMHA, Eria, etc.), I decided to finally give C4 Ultimate it's chance. I had used the original C4 in the past and never really thought much of it. Seemed like a pretty safe pre-workout, albeit underdosed in a few categories. C4 Ultimate really lives up to its name, however. There's no underdosing on this label, as you get full shots of Cit-Mal, Beta-Alanine, Betanine, and Taurine. The 300 mg of caffeine falls right into the sweet spot for me, as 400 mg is reserved for days I want my eyes to pop out of my skull, and 200 mg for those low-key workouts. It's a clean energy ride, and doesn't feature a crash at the end. Only real complaint I have is that despite the caffeine amount being disclosed, the rest of the Energy & Focus blend is not. Also, the only flavor I tried is Sour Batch Bros. It's not necessarily bad, just mundane. More like a mute gummy-worm flavor, yet it still mixes easily and doesn't come out like syrup. In all, I'd say this is the best non-exotic stimulant pre-workout I've tried.

Have been using Dymatize pre-workout for sometime. Good product but I decided to try something different and went for the Cellucor C4 Ultimate. The flavor Orange Mango was not bad. More importantly it thoroughly dissolved in the shaker. No grainy residue on the bottom of the shaker like Dymatize. My workout at the gym was even better than when using Dymatize. Seemed to have more strength and stamina. When I finish the last of my Dymatize I will be switching to Cellucor C4 Ultimate. For info, I am a 67 year old male who has been training for about 40 years.

The worst pre workout ever. No energy, no effects on my workout. I was using Pre-Gym and Nitraflex before this and both of them were amazing. After reading the reviews, I decided to change my pre-workout and I'm highly disappointed. Stomach issues, blue stool and fatigue are just some of the problems with this product. DO NOT ORDER! I thought because of the premium price Cellucor might've put better ingredients but no. This is as bad as they come.

I normally don't write reviews, but these flavors required it. I chose the Sour Batch and Strawberry Watermelon based off ratings and they were both terrible. Both me and my husband (who loves sour) had a hard time getting them down. The strawberry had a weird, but strong plastic flavor. The Orange Mango, which I ordered on a whim, was fantastic and easy to get down. Highly recommend!

Aug 12, 2019

Didn't do a thing to me but it tasted real good! I felt no difference in energy, no tingles, no pump.

Aug 10, 2019

Def had great pumps and strong lifts with this pre workout def one of the better ones out there. I had to stop using this because my stomach didn't agree with the artificial coloring and flavors for some reason this would destroy my stomach

Balanced dosage in the various ingredients.

Now that's a good pre-workout buzz...... Liked the stuff. Has most of what I look for in a pre-workout. And all the energy. Got me hopped up for my workout. Recommend.

Mar 31, 2019

Disclaimer: I havent had a pre workout in a very long time and received this as a sample from another product ordered. With that said, I found that this product greatly enhanced my workout and will consider purchasing, but at the price listed I'm tempted to look elsewhere hoping for similar results.

This is a great Pre workout! Love the energy boost, the pump is great. Keeps me focused and going the whole workout! However.... The Blue Razz is little heavy on the "FD&C Blue#1. I feel like it doesn't really need to be so heavy on the blue dye lol, but that's my opinion. (It is the dye C4 uses to make it blue. It is a very strong dye and if you are like me, my body does not process it well and most comes out later. something to keep in mind, but does not stop me from using this amazing product!)
