The Ultimate Cellucor C4 Extreme Pre Workout Review

Pre workout drinks and powders are among the most popular fitness supplements on the market, as the wide reaching ad campaigns have convinced people that they will make reaching your goal much easier.

Yet, while this will be true in some instances, most people have no clue what they are buying.

Pre workouts are usually filled with a long list of ingredients with scientific names that the average person will have never heard of. This can make separating the great pre workouts from the good or even completely useless ones extremely challenging to the untrained eye.

One pre workout that has gained a great deal of popularity in recent times is the Cellucor C4 Extreme Pre Workout.

Made by a reputable brand in the fitness supplement industry, you would think it is likely to be one of the more reliable and effective options on the market; but is it though?

Well, join us, as we conduct the ultimate Cellucor C4 Extreme Pre Workout review, and we can make that decision for ourselves.

Who Are Cellucor?

Cellucor are an American sports nutrition brand based in Austin, Texas and owned by Nutrabolt.

After launching in 2009 in partnership with GNC, they released their first pre workout powder, C4 Extreme Pre Workout, in 2011.

Over the decade plus since, they have gradually expanded and released ranges of protein powders, pre workouts, amino acids, nitric oxide boosters, ready to drink beverages, testosterone boosters, and weight loss supplements, the vast majority of which are NSF certified.

Having established themselves as one of the most popular and successful companies in the industry, their products are now available through major retailers including Costco, Target, and Walmart.

They have even joined with Mars Incorporated to create collaborations, with fitness supplements now available in the flavours of some of the most popular candy and confectionary on the planet.

C4 Extreme Pre Workout Ingredients: What Is It Made Of?

The best way to fully understand any product is to look at the ingredients that make it what it is. That way, you will be able to see exactly what it is capable of doing and know just how it does it, giving you the ability to judge it honestly and fairly.

That is particularly true with pre workouts as, like I mentioned before, they are often filled with a wide range of uncommon components.

With that in mind, before we begin our Cellucor C4 Extreme Pre Workout review, we will examine each of the ingredients that it is made of in great detail.

Caffeine Anhydrous

Caffeine anhydrous is simply regular caffeine in dehydrated form.

Known for its incredible ability to boost energy and reduce fatigue, caffeine is the core component in most pre workouts and energy drinks, as well as drinks like tea and coffee, making it the most commonly used stimulant on Earth.

Beyond its ability boost energy levels and prevent tiredness from setting in, caffeine also has the added benefit of increasing the body’s rate of lipolysis, which is the process that converts stored fat cells into energy. It does this by both raising your metabolism, as well as your internal temperature.

This not only adds to the energy producing effects it is added to the C4 Extreme Pre Workout for, but also allows it to function as a mild fat burner as well.

The 200mg present in each serving is more than enough to provide you with maximal boosts to both your physical energy and mental alertness.

CarnoSyn Beta-Alanine

CarnoSyn Beta-Alanine is a patented version of the beta amino acid and is considered to be one of the core ingredients that allows the C4 Extreme Pre Workout to function in the way that it does.

Beta Alanine is a common ingredient in most good pre workouts and is the component responsible for causing the tingling sensation that is synonymous with these types of supplements. Each serving of the C4 Extreme Pre Workout contains a substantial 2 gram portion of their patented variety.

Its primary reason for inclusion in pre workouts is that it converts into carnosine when it reaches the muscle cells, which helps to disperse the lactic acid produced while exercising. This prevents the onset of fatigue and promotes muscular endurance.

Beyond this, beta alanine has also been shown to optimise some of the body’s intramuscular functions, including enhancing both your physical and mental performance, while also increasing metabolism, enabling you to burn fat and produce energy at a higher rate.

Nitramax Citrulline Nitrate (NO3-C)

Cellucor’s patented Nitramax Citrulline Nitrate is a combination of the amino acid citrulline and nitrates, a type of NO salt.

Each compound by itself is known to amplify the effects of nitric oxide on the body, but both become infinitely more effective when used in combination with each other.

The primary role of nitric oxide in the body is to encourage the smooth muscle in the blood vessels to relax, causing the vessels to vasodilate or widen, thereby increasing the blood flow.

By increasing blood flow to the skeletal muscles, you make them feel stronger, creating a sensation bodybuilders and weightlifters commonly refer to as “the pump”, while also enhancing both their performance and endurance.

With 1 gram of Cellucor’s patented Nitramax Citrulline Nitrate in every serving of C4 Extreme Pre Workout, it will maximise the presence and performance of nitric oxide in your body, giving you both the mental and physical support you need to take your workouts to the next level.

Creatine Nitrate (NO3-T)

Creatine is a naturally occurring compound that is essential for the anaerobic production of energy in humans to continue occurring beyond just a few seconds.

One of the most popular fitness supplements on the market, it is proven to improve both performance and appearance.

The effect it has on the production of energy allows you to work out harder for longer, pushing your body to greater lengths and making larger improvements.

Meanwhile, its ability to retain water gives the muscles a larger look and a pumped feeling, both of which enhance mental focus and drive.

Beyond this, the form of creatine used in the C4 Extreme Pre Workout is also bonded with nitrates. This allows it to function as an NO booster, making the effects of the included Nitramax Citrulline Nitrate more potent in the process.

1 gram of this two in one performance and pump amplifier is included in every serving of the C4 Extreme Pre Workout.

Huperzine A

Huperzine A is a type of alkaloid found in plants known as firmosses and is a known inhibitor of the neurotransmitter acetylcholine, which affects the ability of the central nervous system to send the impulses required to make muscles contract.

It is a substance not normally found in fitness supplements, as its most commonly utilised benefits include its ability to enhance memory, learning, concentration, and other mental functions, as well as improve quality of sleep. It is even being trialled as a treatment for Alzheimer’s disease.

However, the improved sleep and concentration it offers can both be incredibly beneficial to workouts as well.

Better sleep will make you more energetic during sessions, allowing you to train harder, while being more restful will also give your muscles more opportunity to repair.

Meanwhile, improved concentration allows for a better mind muscle connection to be made during your workouts, increasing the productivity and muscular improvements achieved in each session. A 50 mcg dose of Huperzine A is included in each serving of the C4 Extreme Pre Workout.

N-Acetyl L-Tyrosine

N-Acetyl L-Tyrosine is an amino acid derivative of the primary amino acid tyrosine, the main goal of which is to regulate the neurotransmitter levels in plasma.

Studies have shown that it is incredibly effective for allowing people to retain full mental and physical ability when in stressful situations, such as when they are cold, fatigued, sleep derived, or required to perform prolonged periods of physical activity.

This makes the 200mg of N-Acetyl L-Tyrosine present in each serving of the C4 Extreme Pre Workout perfect for keeping you focused and upbeat during the long, physically taxing workouts you will be required to complete in order to achieve your goals.

How Healthy Is The C4 Extreme Pre Workout?

C4 Extreme Pre Workout Powder | Icy Blue Razz C4 Extreme Pre Workout Powder | Icy Blue Razz

Pre-workout Energy Supplement for Men & Women | 200mg Caffeine + Beta Alanine + Creatine | 30 Servings.

The C4 Extreme Pre Workout is designed primarily to produce results, rather than promoting health.

Being made from a number of chemicals that alter your body’s functions and featuring a variety of artificial colours and flavours means it is never going to be classed as a traditionally “healthy” drink.

However, that doesn’t automatically mean it is unhealthy either. Containing zero sugar and no calories, it can conveniently be added to your daily routine without worrying about it making you gain weight or develop conditions like diabetes.

It also gives you the ability to enhance your physical performance, helping you to train harder in the gym and make changes that will improve your health.

So, whether or not C4 Extreme Pre Workout is healthy or not really depends on your own perspective. That said, it certainly isn’t unhealthy.

Does The C4 Extreme Pre Workout Have Any Side Effects?

The ingredients found in Cellucor’s C4 Extreme Pre Workout have been linked to a large number of side effects.

These include addiction, anxiety, bloating, dehydration, diarrhoea, dizziness, excessive saliva production fatigue, fainting, flushing, headaches, increased heart rate, indigestion, insomnia, irregular heartbeats, low blood pressure, muscle cramps and twitching, nausea, restlessness, shaking, sweating, slurred speech, vomiting, weight gain, and damage to the kidneys and liver.

Many are also not usually recommended for those pregnant or breastfeeding, while some can cause interactions with other medications, such as beta blockers, acetylcholinesterase inhibitors and other cholinergic agents, and a range of heart medicines, which could be potentially harmful.

However, the doses found in Cellucor’s C4 Extreme Pre Workout are reasonably low and are only present in quantities which are just enough to produce the desired effects.

This has led to it being classed as relatively safe for use by most people, although it should still be avoided by anyone who is allergic to any of its ingredients or dealing with any of the situations listed above.

Frequently Asked Questions (FAQS)

Before we wrap up our ultimate C4 Extreme Pre Workout review, I want to quickly address a few of the most frequently asked questions people have about the supplement.

This will help to ensure everyone has a completely clear picture of the product, allowing them to definitively make their own conclusion on whether or not it is right for them.

Is C4 Extreme Pre Workout A Fat Burner?

C4 Extreme Pre Workout is not designed as a fat burner.

It is a pre workout supplement, the main aim of which is to provide users with the energy and mental focus to complete more challenging workouts, so that they can achieve greater results.

However, two of the ingredients included in the C4 Extreme Pre Workout, beta-alanine and caffeine, are common ingredients in fat burning supplements, as they increase your body’s lipolytic, metabolic, and thermogenetic rates, all of which enhance the rate at which your body burns fat.

So, while the C4 Extreme Pre Workout isn’t designed as a fat burner, it can offer some similar qualities, making it a good pre workout choice for those who are hoping to improve their body composition.

Will The C4 Extreme Pre Workout Help You Build Muscle?

The C4 Extreme Pre Workout doesn’t contain any key nutrients like protein or carbohydrates, so will not directly help you to build muscle.

However, it does allow you to complete longer, more intense workouts, which are the best way of achieving muscular development.

So, while the C4 Extreme Pre Workout won’t directly lead to gains in muscle on its own, it is a key component to helping you make the necessary changes to achieve that aim as quickly as possible.

Those after a product specifically to help them build muscle will be better off turning to a protein powder, or even using one in combination with a pre workout.

The Vega Sport Protein powder is a fabulous option, which will meet the needs of the vast majority of people.

Then, you also have non-dairy, sugar free, and vegan protein powders, ensuring there are options available for all, no matter your dietary requirements.

How Do You Take The C4 Extreme Pre Workout?

The C4 Extreme Pre Workout is a powdered drink mix.

To consume it, you need to add one level 5.7 gram (0.2 oz) scoop (included in each tub) to 170 ml (6 fl. Oz) of cold water and mix well for at least 30 seconds.

For best results, mix the drink using a shaker bottle.

The drink should then be consumed between 20 to 30 minutes prior to a workout, which will give it plenty of time to take effect.

It should not be consumed within 3 hours of when you intend to go to bed, as this could cause issues such as restlessness and insomnia, due to the high caffeine content.

How Long Will The Effects Of The C4 Extreme Pre Workout Last?

Most people will feel the effects of the C4 Extreme Pre Workout starting to occur from 20 to a maximum of 45 minutes after its consumption.

These effects will then usually last up to 3 hours for most people, while almost everyone should see all the effects wear off after a maximum of 6 hours.

Like with any pre workout, the exact effects and duration may vary, depending on how sensitive you are to any of its ingredients or any of the other supplements and medications you may be taking.

There are ways to estimate the precise duration of the effects of pre workouts, and this is something that is important for those hoping to achieve maximum results from such supplements.
