Nowadays, C4 Sport Cellucor is one of the most recommended products by bodybuilders and athletes thanks to its surprising results in promoting energy boosts and improving the transformation of muscles and more.

Cellucor C4 Ingredients

There are a few ingredients that compose Cellucor C4. The product has both individual ingredients as well as an “Explosive Blend,” providing results and benefits for the performance and overall response for muscles, cognitive system, and even some organs.

Beta Alanine

One of the main ingredients, Beta-Alanine, is an amino acid that increases muscular levels of carnosine, promoting fatigue resistance. It comes in a 1.6 gram per Cellucor C4 scoop.

Creatine Nitrate

cellucor c4 ingredients creatine

Creatine nitrate, another main ingredient of the supplement, improves strength, power, and resistance during exercises. It provides water retention in muscles, making them more likely to support weight training for long hours, getting excellent post-workout effects as well, as stated in this research.

L-Arginine AAKG

L-Arginine AAKG is a compound that can be found in the supplement as well, which enhances body functions like blood flow, muscle oxygenation, and increases nitric oxide levels for more efficient nutrient delivery throughout the body. And of course, it also helps to promote more resistance and concentration during anaerobic and weight exercise, according to some studies.

Caffeine Anhydrous

Caffeine Anhydrous, a main ingredient of the product, can also have improvements in the body and mind. As a caffeine low in water, it is specially designed to provide a much faster effect on humans. According to this study, it helps to increase performance, strength, and concentration.

Tyrosine and Theacrine

Tyrosine and Theacrine can also be found inside Cellucor C4, an amino acid that improves neuromuscular performance. When they are combined with caffeine, the supplement works even more efficiently, providing synergistic effects that increase fatigue resistance, more focus, and an active release of adrenaline for a more extended work out activity.

cellucor c4 claims explosive energy

Explosive Energy Blend

On the other hand, we have the famous “Explosive Energy Blend,” which is supposed to come from six ingredients, like niacin, vitamin c, folic acid, mucuna pruriens, and vitamin B12. This blend helps to improve blood flow and dilate blood vessels, convert dopamine into energy, and release stress for better heart rate performance promotes a better recovering phase after workouts, enhances energy and resistance, offers more brain capacity for focus, and eventually makes the nervous system work more efficiently, improving concentration.

How to Use Cellucor C4

The proper way of using it is by taking one scoop of the Cellucor C4 mixed with water 30 minutes before training.

For those who need a performance boost, it is recommended to take an additional scoop mixed with water before or during training. However, it is recommended not to exceed this intake.

Apart from that, the product indications affirm that taking a lot of water before, during and after workouts with Cellucor C4 can improve performance even more. Other Cellucor products like Alpha Amino can increase the effects of the supplement even more.

Bottom Line

Cellucor C4 Benefits

Whether you use the Cellucor C4 50x version or the simple Cellucor C4 blue razz original formula, there’s no doubt it can provide excellent results.

Despite this Cellucor C4 Sport review and many others, no real research validates the benefits and results of the product advertises. However, many other research studies to prove the benefits of Cellucor C4 ingredients, including TheaCrine, L-arginine AAKG, Caffeine Anhydrous, Tyrosine, Beta-Alanine, and creatine hydrate.

On one study for the TeaCrine (Theacrine), it was concluded that the product helped athletes to improve concentration, energy, and focus on a lapse of 2 to 3 hours. Also, it boosted the willingness to exercise and motivation, while reducing fatigue with no side effects or health problems.

cellucor c4 may improve cognition

Another study made on 21 military cadets using Tyrosine during a week of training delivered excellent results on task performance, reducing stress, improving resistance, and promoting anti-fatigue hormones for a much more efficient production both in cognitive and physical events.

For the arginine AAKG, there is a study which concluded the product was not effective in improving muscular performance. However, there is another one who proves the effects of the product on college athletes, finding excellent results for recovering from injuries and a slight increase in performance in training.

For beta-alanine, a research study was done to analyze the results and effectiveness of the product on men and women during exercise. It concluded that the product does help in reducing fatigue and providing more resistance to physical stress by augmenting muscle carnosine.

We can also find Tyrosine in the supplement. This compound is said to promote memory and multitasking performance, a useful feature for exercise and other physical-related activities.

Lastly, we have the results of a study for creatine nitrate, where it was approved and validated by athletes that the product improved physical performance exponentially. In the long run, it promoted muscle growth and better resistance, according to the Journal of Strength and Conditioning Research.

Cellucor C4 Side Effects

The different types of Cellucor C4 gave incredible improvements in performance, strength, and resistance. However, the product is not exempt from side effects. Despite not having any studies disapproving the product with highly dangerous side effects, there are some of its ingredients that could make you hesitant of buying this supplement.

For example, arginine is said to cause diarrhea and other problems in the whole gastrointestinal system. However, it was mostly due to overuse or poorly digested amino acids with arginine.

Tyrosine, another ingredient of the supplement, can also induce specific side effects like stomach irritation, migraine, gastric problems, and nervousness, according to PubChem. This happens due to the mental impact the product has, especially when it is ingested incorrectly, or it is overused.

cellucor c4 potential side effects

But despite these side effects, there are some studies which approved other ingredients, like arginine, as totally safe for the circulatory system. While creatine seems to provide the same type of side effects, improving muscle creation and blood flow without damaging health in any way.

Then we have TeaCrine, or in its compound form, Theacrine. It was studied for eight weeks, and it gave safe results that make it one of the healthiest and highly active ingredients of the supplement.

Caffeine, a popular ingredient in products like Cellucor C4, comes with the risk of side effects like increased heart rate, elevated blood pressure, jitters, and sleeplessness.

Apart from that, it is essential to remember that GNC Cellucor C4 is a product which blends and mixes many ingredients at the same time. So, if single products by themselves do not dangerously affect health, it is still possible that all these ingredients together, as in the supplement, could damage body functions. This is all because there is a lack of evidence from scientific studies directly related to the product Cellucor C4 side effects.

Cellucor C4 Scientific Research

As you may already know, Cellucor C4 50x or any of its other presentations like Cellucor C4 Blue icy razz, provide excellent results for performance, strength, and resistance. But it doesn’t have any research validating these effects or consequences, especially when it comes to studies directly related to the supplement.

As for its ingredients, there are various affirmations and research that could prove how the product works. For example, there is one study that analyzes how Theacrine and caffeine together can improve specific human capacities. It came with results about the increase of performance and how they both were safe. However, it didn’t give any boost to cognitive performance, but delivered some changes in mood and energy, in addition to the other physical effects, according to another research.

Additional research also studied the effects of anhydrate caffeine, analyzing several subjects to see if the intake of this compound could improve the performance or any other physical feature, before, after, or during exercise. As an ergogenic, this type of caffeine created a boost of energy, especially for long and intense workouts. However, it didn’t improve the strength or power in weight exercises or sprints.

Cellucor C4 Alternatives

cellucor c4 alternatives

There are some products like Cellucor C4 that could be perfect substitutes. These products are merchandised the same way as Cellucor C4 blue razz, offering the same type of results and safety benefits.

Among these products, we can find MuscleTech Nanovapor, which promotes excellent concentration and focus improvements, plus superb strength enhancement and much more energy for longer and faster training performance. Also, it helps to grow muscle better than Cellucor C4. However, there are little to no research validating these claims.

Another option could be SANN Fierce Domination, a product that also works well to improve efficiency and strength. It promotes muscle growth and provides excellent gains after workouts. Also, it enhances resistance and endurance.

What Users Are Saying

“Absolutely increases the effectiveness of my workouts. If you haven’t tried pre-workout and want to up your game in your routine, consider taking this. If you take it be certain to stay very hydrated during your exercise and try to carry bottled water around with you because this stuff will make you thirsty. Also don’t try to take it if you are going to be sitting for long periods of time (your body will literally shut down) or you want to go to bed within a few hours of taking it (will keep you awake).”

“This product definitely delivers the energy I need for a workout, but the flavor makes be dread taking it. So far, I’ve loved all the flavors this brand has to offer, but this one tastes incredible artificial and leaves a horrible taste in my mouth. I would receommend any flavor, except for the pink lemonade.”

“Pass on this one. Flavor was good but immediate stomach issues that will leave you running to the bathroom mid set. I thought i had ibs untill i stopped taking this and the problems went away. Very painful. I read you really need to mix one scoop with 16 ounces of water to help but even than it was of no use symptoms stayed.”

The Bottom Line on Cellucor C4?

So, will Cellucor C4 pre-workout provide explosive energy? Well, we like that it contains a few natural ingredients and that the company is a trusted name in the industry. But,
the only concern was the few reviews mentioning the effectiveness. Based on the profile, available research, and positive testimonials, we see think this one is a winner.

Another one that’s caught our attention is a supplement containing ingredients backed by science and positive user reviews.

Among the best products we’ve seen this year is one called Boost. The formula contains nine clinically-tested ingredients, with results often published in journals. Customers tell us they see great results.

Also, the company behind Boost is confident you’ll love their supplement, they’re offering a 120-day money-back guarantee and 2-Week Sample.

    I like C4… I been using it for a year now. I use it for my circuit training and regular workouts and I get a lot of energy and strength. It helped me stay motivated. I use to be 198 and I’m down to 145. I also use it when I’m tired and need energy to focus on my school assignments.. It wakes me up and keeps me focused.

    I’ve not experienced any jitters or ill effects due to the caffeine, but I have found that it works very well with me. I’ve just used it this week alone, and my performance is 50% better. I can breathe better during the workout, my endurance has improved and I feel really good after the workout. It’s been so long since i’ve had muscle soreness due to harder efforts, which I have now. I wanted to better understand what ingredients are in the C4. I am more concerned with how long will this product really last, or is this just working because it’s new to my system. How will it work over a period of time?. Do you have any idea where I can find these answers.

      Some dieters experienced the same. The only thing you can hope for is if 1). your body accustoms itself to the formula, 2). you reduce your dosage until the effects subside or 3). continue to exercise to increase healthy blood follow.

    Reply
    • Stephen (Editor)

      Bert, the company recommends taking one serving with 4 to 6 ounces of water 20 to 30 minutes before a workout. After finding the amount that suits you, you may add scoops. Do not exceed two servings in a 24-hour period.

    I just want to say that this stuff really works! Not the best taste in the world, but thanks to this amazing product, I have the boost and energy I need after a long day at work. Before C4, it would take me 45 minutes to walk/run a 5K Marathon. I have been taking C4 for four months now, and I’m so happy to share that I am now running at a perfect pace and breaking my own personal record of a 5K Marathon in 30 minutes. I also want to share to others, that do not give up on this product. The first week of taking C4, I almost gave up on it because of the tingly “wired” effects I was feeling throughout my body, so what I did the second week, was use only half a scoop to the same amount of water….and this did it for me! I am one happy user! 🙂

          Hi Rob. We’re positive gaining muscle is not solely dependent on eating an excessive amount of calories. Macronutrients, especially carbohydrates and protein, play an important role, but eating too much can lead to weight gain.

        It helps muscle growth if you do weights. It increases how much cardio you can do if you do that.
