Product Overview

C4 Extreme
C4 Extreme Container

Performance Energy Evolved

Over two years in the making, spanning multiple formula tweaks and hundreds of flavor tests, C4® Extreme has been re-engineered and re-imagined from the ground up to help support explosive energy, extreme performance, powerful pumps, and mental alertness.* This is the product that defined a category, now evolved and updated.

We ran C4® Extreme through several hundred rounds of flavor sampling to make sure it exceeds every expectation, and we didn't settle for anything less than the best. If a flavor didn't measure up, we moved on. We're proud to say that C4® Extreme's flavor array wins in every way — including our new, naturally sweetened flavors.

Featuring

Nitramax (NO3-C)™

Unlike Citrulline or Citrulline Malate, which work through a single mechanism, Nitramax™ supports two mechanisms of NO creation, the arginine pathway (eNOS) and the nitrate-nitrite conversion system, to help promote the ultimate pump.* Created by bonding citrulline with patented nitrates, Nitramax (NO3-C)™ is an advanced compound that delivers dual-pathway nitric oxide (NO) support.*

Introducing Project Clear Evolution: our mission to set a higher standard in sports nutrition. To elevate the entire C4® family—and beyond—by pioneering the next generation of premium, better-for-you performance supplements.

We're swapping artificial colors and flavors in favor of natural options, peeling back prop blends to showcase all the performance ingredients that make our products tick, and boosting our formulas with enhanced inputs for extreme performance.* This is the future of sports nutrition, and it starts with the all-new C4® Extreme.

I used this after a 4 week steam break. I am very happy with it and would highly recommend it. The profile is clean and straight forward, the taste is awesome, and the energy is great and lasting. You will not be disappointed.

Solid product. Taste is phenomenal and the profile is nice and simple. Fully disclosed and natural flavors and no dyes. I'd imagine this would be Cellucor reacting to the trend whores who wanna be "all natural" and fully disclosed. Either way, the result is solid. Killer energy, pumps, and focus. Love this stuff!

Cellucor does it again with new C4 Extreme. The Icy Blue Razz is on point, and provides me with the needed energy to hit the gym after long day at work. Noticed that the itchy feeling I would get before is gone, but the energy level still awesome! I have recommended it to my gym buddies as I usually the first one to try new items out.

I had the chance to try the new C4 Extreme after a very intense athletic event. On a week I was spent from the weekend I hit both a leg day and upper body day. The results were great. I had too very laser focused session that didn’t that over stimmed felling you can get. The Beta-Alanine hits just right to give you the endurance you need to power through. I definitely recommend giving it a try.

I knew that something was different when I opened the container and the scoop was on top!!!! It has a light, fresh aroma that transfers to the taste when mixed with water. I used it in the gym, when pulling flood soaked carpeting and padding from a house and in a long, 2 day softball tournament in the blazing and humid Missouri summer swelter. Sure do like the fact that it is free of artificial dyes and flavors as well as those 'secret' proprietary blends. The Carnosyn dosage works well for me. Due to the extreme heat and humidity conditions, I lightened up the dosage as I was drinking incredible amounts of water those two days. It worked wonders. I was still hitting home runs in the last championship game at 5 PM as I was at the 8 AM game. Definitely recommend it for sports strength and endurance. Keep producing effective, high quality products, Cellucor!

Cellucor does it again; flavor is on point and one scoop gives you a great burst of energy that lasts without any crash. I appreciate the transparency of the label and lack of proprietary blend, and I am glad Cellucor dropped artificial dyes and flavors for this product. Overall, and excellent product with a cleaner and more transparent label. Definitely worth a try!

This new variation of Cellucor C4 surprised me because it dissolves great because it is such a finely ground powder, gave me a very smooth uptick in energy (no spike - no fall off a plateau), and the flavor is on point like always!

The flavor of this is spot on. Not too sweet, and not too watered down. The energy I get from this is good. It does not make me feel cracked out with energy, but yet I still feel I have enough to get through the workout with ease. The pumps I get from this is awesome! Even after my first exercise, I can feel my arms and chest feel more full and pumped! I like Cellucor is moving towards the Clear, transparent label with no prop. blends. I also can tell there is Beta-Alanine in this with the tingles! Overall a very good pre!

I love the simple yet effective energy blend in this preworkout. The only reason I gave it a 9/10 for the flavor is because I am not a huge fan of blue razz flavored stuff since I mix my preworkout with carbonated flavored water and I have a hard time finding flavors that go with blue razz. Otherwise, it is a great product! It didn't take too long to kick in and didn't leave my skin tingling or feeling prickly like some of the other preworkouts I have tried.

I recently received this new C4 and I’m loving it! I am a huge fan of the fully transparent label, the 200mg of caffeine is perfect, it mixes great, and taste great. I’m not a huge fan of blue razz but I like this one! Can’t wait to do some of the other flavors down the road.

I have recently started using this before runs and has really helped me keep me on task. I am better able to focus on the mechanics of my stride and I am finishing my runs stronger than before. It also makes me feel pumped and ready to go, but not anxious or jittery. I am going to keep using it and I am excited to try other flavors too.
