What Is C4 Ripped?

It’s noteworthy that Cellucor operates under the umbrella of Nutrabolt, an independently owned sports nutrition company based in Austin, Texas.

C4 Ripped Claims

C4 Ripped Claims

Cellucor C4 Ripped claims to increase the rate of a user’s fat-burning and give the explosive energy of C4, enhancing workout efficiency. It does this by elevating physical and mental activity without affecting the overall health.

Since it is composed of many natural ingredients that the body needs while performing, it also minimizes the possibility of muscle cramps by increasing muscular durability. One scoop per day is enough to allow you to reach your training target.


The C4 Ripped Ingredients

C4 Ripped contains multiple ingredients, both natural and non-herbal, that pose many benefits.

It also has various artificial flavorings, sweeteners, and anti-caking agents, including sucralose and acesulfame potassium.

The label claims that the product also contains 400% of the RDI of Vitamin C and a dose of Vitamin B6, B12, niacin, and folic acid.

The main ingredients C4 Ripped ingredients include:


Beta-alanine is a non-essential amino acid. In the human body, beta-alanine combines with L-histidine to form carnosine, which goes in the brain and muscles.

Arginine AGK

Arginine AGK also counts as a non-essential amino acid. However, it is an essential component for bodybuilders, as it stimulates the body to build up muscle mass, endure more, and have better strength.

According to The National Library of Medicine, it stimulates the body to produce additional nitric oxide, which is a vasodilator.

L-Carnitine — L-Tartrate

An amino acid, L-carnitine – L-tartrate, plays an essential role in metabolism. The National Library of Medicine shares research showing l-carnitine helps with fat loss.

L-carnitine affects testosterone, the male hormone that is responsible for strengthening the skeletal muscle via protein production. It can lead to increased muscle mass accompanied by a decrease in body weight and reduced physical and mental fatigue.

Green Coffee Extract

Green coffee extract is famous for its possible effect on fat loss.

Green coffee beans in a bunch on stem

Information shared by Gastroenterology Research and Practice shares that green coffee bean may improve weight-loss, but better-quality studies are required for further support.


It is an extract form of cayenne pepper (capsicum). Another name for capsicum is chili pepper. It has a noticeable effect on burning fat by boosting metabolism. It contributes to fat oxidization in case of low physical activity intensity, burning more than the human body usually does on its own.

Coleus Forskohlii

Upon extraction from the plant Plectranthus barbatus (Coleus Forskohlii), you get forskolin. As per the National Library of Medicine, this extract is for increasing muscle performance and mass as well as weight loss.

There are two reasons behind its effect:

  • It increases cyclic-AMP (adenosine monophosphate), which is a compound in the human body responsible for the breaking down of fats. It helps in fats oxidation, providing the human body with necessary fuel while working out.
  • Its ability to mimic testosterone, same as what L-carnitine -L-tartrate, increasing muscle mass, muscle performance and strength.

Other ingredients found in C4 Ripped include velvet bean seed extract, caffeine, and n-acetyl-l-tyrosine.



C4 Ripped reviews were quite positive. Many athletes and bodybuilders approved the effectiveness of this formula and added that the tasty flavor lasts for a long time.

Several users claimed this is one of the best pre-workout supplements they have ever taken.

Research of each active ingredient shows this combination of C4 Ripped ingredients gives it a synergistic effect. It allegedly takes only 15-20 minutes to feel the rush of power.

A C4 Ripped pre-workout bodybuilding review showed that the product:

  • Increases muscle performance, mass, and strength
  • Elevates mental activity
  • Aids in muscle durability
  • Prevents lactic acid accumulation
  • Improves fat-burning metabolism

However, some Cellucor C4 Ripped bodybuilding reviews found that product efficiency depends on daily caffeine intake. Athletes who usually drink coffee have a high tolerance for this specific ingredient. C4 Ripped contains about as much caffeine as 1.5 cups of coffee, plus some tyrosine.

It means the concentration of green coffee extract in this formula is not enough to function since the human body needs a higher concentration of green coffee extract to be effective.

Athletes who have built a caffeine tolerance can upgrade from one scoop to two to see results, which might put them at risk of over-all ingredients overdose.


Cellucor C4 Ripped Benefits And Results

Cellucor C4 Ripped is highly beneficial due to the presence of over seven active ingredients. One serving is enough for a prolonged workout without exhaustion.

Due to amino acid supplements, the body starts to build up and shape muscle so that much effort can be made in one training, allowing more lipolysis to occur.

Weight Loss

This formula is tasty; however, taking it does not mean you’re over-eating sugar. The C4 Ripped calorie count is zero.

C4 Ripped Directions

C4 Ripped comes with 30 servings and a six-gram scoop.

Blend a scoop of this product in 6 fl. oz. of water, 20-30 minutes before working out for maximum efficiency.

Once you’ve assessed your tolerance, you can try taking one additional serving (another scoop) with serving taken before training.

Beginners may find one scoop a day suitable, while experienced athletes may need to take two.  It is advisable not to take more than two scoops per day to avoid side effects and overdose toxicity. Also, users taking two scoops should not take any caffeine-related products within six hours of taking C4 Ripped.

During the workout, ensure that you stay hydrated with water or an exercise performance drink.

You could feel a harmless tingling sensation, which is linked to beta-alanine.


C4 Ripped Flavors

  • Icy Blue Razz
  • Raspberry Lemonade
  • Cherry Limeade
  • Fruit Punch

Based on the effectiveness of its ingredients, there is a good chance this product works.

Also, the fact that the FDA approved C4 Ripped is a positive sign. Clinical research that reliable laboratories have carried out indicates that this product is effective in weight loss.

C4 Ripped Vs. C4

Cellucor C4 is the template for all other forms of C4.

Cellucor C4 is manufactured as a workout-booster. It increases muscle mass and durability; its ingredient is only beta-alanine, a common ingredient in all pre-workout supplements that is responsible for the elimination of lactic acid and maintaining a balanced pH.

C4 Mass Vs. C4 Ripped

Usually, all Cellucor C4 products have the same template as the main ingredient that helps in muscle durability and bulk-up. But when talking about C4 Mass vs. C4 Ripped, it is evident that C4 Mass is for athletes who would like to increase their muscle mass even more than shedding or shredding down. C4 Ripped, and Mass have almost the same ingredients: both Ripped and Mass contain beta-alanine and arginine.

However, there is a minor difference in C4 Mass, as it contains 52.5 grams of sugars and carbohydrates (Kroc Priya carb blend) as a muscle mass aid. In C4 Ripped, L-carnitine is to increase body fat-loss.

Right now, C4 Mass is not available for purchase from the official website.

C4 Ripped Vs. C4 Extreme

This form of the Cellucor C4 is extreme in every ingredient, with higher doses of all active ingredients to burn body fat as much as possible, giving maximum strength.

C4 Ripped vs. C4 Extreme showed a significant ingredient addition in Extreme, citrulline malate, as well as a much larger dose of caffeine anhydrous. Extreme is ranked as one of the top 10 pre-workout supplements in the world.

C4 Ripped On The Go

It is the same formula as the powder in C4 Ripped but packed in a bottle. It gives a shot of energy that will be useful not only in the gym but also in any other activity.

A bottle of C4 Ripped on The Go is enough to boost your potential and elevate your mental activity.


C4 Ripped Price

C4 Ripped Price

C4 Ripped Pre-Workout Powder is competitively priced compared to other pre-workout supplements in the market. The average cost per serving comes to around $1.33, with most vendors offering it at approximately $40 for a 30-serving container. If you opt to purchase it from Amazon, the price is slightly lower, hovering just above $30 per can, translating to a little over $1 per scoop. However, the actual cost may vary based on factors such as flavor and the specific retailer you choose.

On the official website, C4 Ripped Pre-Workout Powder is listed at $39.99 for a one-time purchase.

What Users Are Saying

What Users Are Saying

“Ripped actually works and is one of the few to give me the tingling feeling to workout. But if also causes me to throw up before/during workout.”

“I originally purchased this because I thought it would speed up my metabolism. I didn’t notice any additional weight loss, however, I did have a lot of energy for my workouts without the increased anxiety. I am still a C4 user to this day!”

“I have used C4 for many years and decided to try RIPPED. The taste is horrible and I can barely stomach a serving. But, I hate to waste money so I’m powering through. It tastes very chemically and even my boyfriend gets the burn when he tried it. I joked with him that I thought maybe someone was trying to poison us by adding something to it. I would never order this product again or recommend it to anyone. I used fruit punch which is the flavor I have always ordered. Packaging seems legit and wasn’t clumpy like some experienced. But maybe it’s some awful new formula or taking shortcuts with the ingredients. Either way, it’s lose lose!! Don’t buy!”
