Cellucor C4 Ultimate Review
Get ready for a pre-workout like none before - Cellucor C4 Ultimate Pre-Workout is here! You're probably already keen to try this product. Anything with the word Ultimate in it has to be pretty good, right? Well sit tight, have a read of our C4 Ultimate review, and let us tell you about the ins and outs of this monstrous new pre-workout. We bet you'll be itching to buy it when we're done.

Cellucor has engineered C4 Ultimate to be the most hard-hitting, intense, focused pre-workout on the market. It's a pretty big task as there are a lot of pre-workouts on the market today. It's an even bigger task as while Cellucor's previous versions of C4 have been wildly popular, many users find that the latest C4 Gen4 Pre-workout ) just isn't enough to get them pumping at the gym. Even Cellucor's C4 X50 Pre Workout, which claims to be 50% more explosive than the original C4, doesn't impress some of the hardcore PWO fans.

Let's take a look at a comparison of all the current pre-workout's available from Cellucor. (Note: Only C4 Original and C4 Ripped currently available for sale in New Zealand).

c4 ultimate review

Quite simply, Cellucor have loaded C4 Ultimate with some serious doses of intense pump amplifiers, endurance boosters, mood enhancers and nootropics to enhance physical performance. C4 ultimate matches your obsession with being better than you were yesterday. This isn't a pre-workout for your first time. C4 Ultimate is designed to help you push yourself to your ultimate limit. Ultimate energy, ultimate focus, ultimate pumps, ultimate endurance, and ultimate performance.

But anyone can make claims that this is the "ultimate" pre-workout. We've written this C4 Ultimate review to help explain how and why this is the most ultimate pre-workout, and help you understand how this product works. If you don't really care what's in it and just want to know whether you should buy it or not, we'll list the Pros and Cons first.


  • Includes well dosed ingredients to enhance physical performance (6g Citrulline Malate, 3.2g Beta Alanine, 1.5g Creatine Nitrate)

  • Mostly transparently label

  • Extreme energy and focus(300mg Caffeine as well as TeaCrine and Nitrosigine)

  • Smoother longer lasting energy with no jitters or crash

  • Massive muscle pumps

  • Full body feeling (you'll feel this in more than just your hands)

  • Increased workout performance and endurance

  • Increased strength and power

  • Hits hard like the first time every time (We know, we tried it!)

  • Great tasting flavours (Orange Mango is a must try)


  • Large scoop size and ingredient doses means price is $3.22-$3.99 per serve

  • Full 3.2g Beta Alanine dose may be too much for some people

  • Only 1g Creatine so still need to supplement with Creatine

  • 1.5g Betaine Anhydrous not full dose to achieve strength and power benefits

  • 300mg Caffeine is quite high

  • Not for first time users

Depending on your level of experience with pre workouts, you're probably thinking "yes I need this!" or "no, not for me". If you're somewhere in the middle, try half a scoop to assess your tolerance. You'll still see plenty of benefits from just half a scoop and can always use the full scoop next time.

Onto the science stuff of the C4 Ultimate Review!

c4 ultimate scoop

Cellucor have made the "what's in it?" part easy for us - C4 Ultimate has a mostly transparent label. That means that they've listed most of the quantities of the ingredients in the product.

6g Citrulline Malate

Citrulline Malate is an amino acid compound that acts as a nitrix oxide booster. By boosting nitric oxide levels, Citrulline Malate increases circulation, vasodilation, and muscle pumps. This helps your body transport more nutrient and blood to your muscles for enhanced performance. Citrulline Malate also supports ATP production which is the production of energy used for the biochemical reactions involved in any muscle contractions.

3.2g CarnoSyn Beta Alanine

The clinically studied dose of Beta Alanine that is used in most pre-workouts is around 1.6-2g. Cellucor have loaded C4 Ultimate with 3.2g so get ready for some serious tingles! Studies do recommend taking 3.2g Beta Alanine per day but advise splitting it into two or more doses throughout the day to limit side effects such as tingling. While the tingling is a harmless side-effect called paresthesia, it can be quite startling if not experienced before. This side effect usually decreases as your body becomes accustomed to Beta Alanine, however some people do avoid Beta Alanine because of this side effect.

This endurance booster has been used in previous c4 versions but never at this dosage. Beta Alanine supports the body's ability to buffer lactic acid (that muscle burn feeling you get during an anaerobic workout). The build up of lactic acid during exercise can effect workout performance so if the body can buffer or clean more lactic acid, workout endurance, power and strength will increase and we will feel less fatigued.

Creatine Nitrate NO3-T 1.5gc4 ultimate muscle pumps

NO3-T is the patented version of creatine nitrate. It contains just over 1g Creatine Monohydrate so you’ll still need to supplement with creatine elsewhere for the daily recommended dose of 5g. But the reason Cellucor really included NO3-T is for the nitrate content (487.5mg) which helps sustain the nitric oxide boost from the Citrulline Malate. Nitrates also help improve blood flow, endurance, power and pumps!

Betaine Anhydrous 1.5g

This muscle building compound is derived from sugar beets and acts as a power and strength booster. Studies show that 2.5g Betaine Anhydrous significantly increases strength, power, and endurance, while alleviating soreness from exercise. At a dose of 1.5g you will still see benefits but probably not as much of a strength and power boost as studies have shown at the full 2.5g dose. You could always top it up with an extra 1g Betaine Anhydrous for the full benefits.

Nitrosigine 1.5g

Oh you thought we'd finished listing the pump amplifying ingredients. Not even close. You're going to need new t-shirts from these massive pumps, perhaps just switch to working out in singlets.

Nitrosigine is a new version of the nitric oxide booster supplement – arginine. Nitrosigine is a patented bonded arginine silicate complex developed by Nutrition21 . Arginine is bonded to silicate to increase it’s bioavailablity.

Nitrosigine begins working in just 15 minutes. The benefits of Nitrosigine include:

  • Increased nitric oxide levels

  • Enhanced bloodflow and vasodilation.

  • Increased muscle pumps

  • Increased energy

  • Reduce muscle damage from exercise

Not only does Nitrosigine boost nitric oxide levels immediately after taking it, but it has also been shown to keep baseline nitric oxide levels elevated for up to two weeks.

Arginine Alpha Ketoglutarate (AAKG) 1g

And more pumps. We told you.

Haven’t we got enough? No one uses arginine anymore! Acutally arginine synergizes with nitrates to reduce nitrate tolerance. This means you won’t build up a tolerance to the nitrates and C4 Ultimate will keep working like the first time without having to increase the dosage.

Taurine 1g

Taurine is a conditionally essential amino which acts as a cell volumiser in skeletal muscle. Taurine supports muscle fullness and endurance, as well as improves performance by enhancing mental focus and cognition.

Ultimate Energy and Focus Blend (805mg)


N-Acetyl-L-Tyrosine is the main focus enhancer in most other c4 preworkouts but here it is only part of the blend. N-Acetyl-L-Tyrosine is used as it is better absorbed than L-tyrosine. It improves mental focus by increasing the two neurotransmitters, noradrenaline and dopamine. It also supports mood and reduces stress.

Caffeine 300mg

At the higher end of the caffeine dosage scale you definitely don't need two scoops anymore. Caffeine is a stimulant most people consume in some form every day. It increases energy, focus, mood, alertness and performance.

Kinetiq Citrus aurantium fruit extract (standardized for p-synephrine content)

This is the branded version of natural Citrus aurantium (bitter orange) extract. It is a non-stimulant ingredient that may support energy and increase alertness.


Teacrine is a patented form of theacrine which is an alkaloid naturally made from caffeine in certain plants. Theacrine provides longer-lasting smooth energy and makes the pre-workout experience feel "like the first time" everytime. It prevents a tolerance build up to caffeine so you will continue to get the full benefits of the 300mg caffeine with each use.

Toothed Clubmoss (Huperzia Serrata) aerial parts extract (standardized for Huperzine A)

Huperzine A aka Toothed Clubmoss Extract prevents the breakdown of acetylcholine - the "learning neurotransmitter". Huperzine inhibits the enzyme directly reponsibly for the breakdown of acetylcholine so indirectly supports the mind muscle connection and sharpens your focus.

As you can see, Cellucor have really loaded up this pre-workout for the ultimate workout experience. You'll need to be quick to get your hands on this one as we predict it will be flying off the shelves.
