C4 Extreme

by Cellucor

    Cellucor has released the 4th Generation of their popular pre-workout supplement, C4. It’s designed as an improvement over previous blends and offers unprecedented benefits to strength, energy, and intra-workout endurance. It contains only clinically-proven ingredients in clear amounts to maximize your performance.

    The first and most important part of any pre-workout is the energy boost it offers. Cellucor C4 contains a brand-specific Explosive Energy Blend that offers an immediate boost. Caffeine anhydrous stops fatigue while amino acids increase protein synthesis. The blend is further supported by natural extracts like mucuna pruriens optimize hormone production like adrenaline and testosterone.

    The second key aspect of a pre-workout is how well it improves your workout “pump.” This is accomplished by increasing blood flow to muscular tissue, which delivers more oxygen and nutrients, resulting in increased muscle fullness and ability. Cellucor C4 includes industry-proven ingredients like beta alanine, arginine, and niacin to ensure you operate and maximum capacity. Finally, C4 supports metabolic function and cell repair with B vitamins and folic acid.

    A brand new ingredient in this version of C4 is creatine nitrate. This compound is quickly becoming the preferred creatine form, beating out even creatine monohydrate. It’s so effective because it doesn’t break down in the stomach like previous creatines. This means it is absorbed more quickly and doesn’t require a large dose to be effective. A 1-gram dose of creatine nitrate can be as effective as a 5-gram dose of monohydrate.

    Cellucor C4 is a powerful pre-workout solution. It stands above the competition by being a complete supplement, covering everything from energy to creatine needs. It comes in a variety of great-tasting flavors, is easy to mix, and is free of all banned substances. Take your workout to the next level with Cellucor C4!

    Pretty Good

    It’s worked great for me so far, I’m 37 and my bench
    And squat max are both at my all time high from
    over 10 yrs ago. There may be better stuff out
    There but for this price it’s hard to beat!

    Didn't measure up to the others

    I’ve taken most of popular pre-workout supplements and this one does not seem to measure up to the others. I had to take multiple servings in order to give me a kick during my workout. I bought mine at Costco because it was cheap and I was pretty disappointed. I probably won’t use it again. It wasn’t a bad product but it wasn’t great either.

    Typical Pre-workout Formula

    I’ve been taking this for about 3 weeks now since I bought it here on I bought the pineapple flavor and the taste is pretty good. I really like the way it tastes but as far as the way I feel during workout, it seems pretty much on par with all other pre-workout supplements. I feel about the same when I take N.O. Xplode or Jack3d Advanced. I would like to try Blue Raspberry. If anyone has taken that, please let me know how it tastes so I don’t waste money.

    Average pre workout, goood price

    I liked it but I don’t think it will help me take me to the next level. I need something a little more extreme. i’m glad I got it here instead of Costco or GNC, I saved like $20.

    Pretty Awesome

    I bought a double pack of c4 in the past. I really liked, and moved on to other preworkouts. I had gotten a free sample and remembered the feeling of the great pump and feel that I got when I took it. It is a really good preworkout that will give you a great pump and even better sweat.

    C4 Extreme, the formula is now a standard...

    Almost all pre-workout supplements are pretty good, with few exceptions, but C4 Extreme is in the top level range. Everyone more or less is using the same ingredients so the HOW they are blended in is the trade secret. With C4 the advantra-z formula for synephrine in combination with the other ingredients brings a sustained energy level and bearable buzz and that is why it is among the most popular. They have standardized a winning formula. I recommend it to everyone. (As usual, the uninitiated in stimulants should start with half dosage in order to see tolerance level, while the initiated and accustomed to stimulants know what they have to do)

    Isn't synephrine bad for you?

    I have heard lately that synephrine is dangerous. That is why I switched from C4 to Oxypump. Could someone that knows more about this subject elaborate?

    I guess selling a dangerous product is profitable...

    All the internet sources I have read say that synephrine is bad for you. I guess making money is more important than a customer’s health. Maybe that is why the moderators never answered my question…

      Re: I guess selling a dangerous product is profitable...

      Synephrine is only dangerous at well above the recommended dosage use for C4 Extreme in the same way that Tylenol is dangerous to your health at above the recommended dosage use. Cellucor’s new G4 formulation of C4 does not contain Synephrine so you will no longer have to worry about that.

    Great pre-workout!

    Since I started taking C4, my workouts have went to a new level. I’m working out longer, doing more reps, completing more challenging lifts, and seeing great overall gains. I will be buying again.

    Cellucor Extreme C4 is an intense pre-workout supplement that focuses on increased energy levels, sharpened focus and stamina, higher endurance, greater strength, and faster muscle growth. Extreme C4 fuels your body with powerful nutrients that will revolutionize the way you workout.


    On training days, begin by taking 1 scoop mixed with 4-6 oz of water 20-30 minutes before training to determine tolerance. After assessing personal tolerance, take 1-2 scoops 20-30 minutes with 4-6 oz of water per scoop. Drink plenty of water during your workout.


    Do not take if you are currently taking nitrates for chest pain or if you are taking medication for erectile dysfunction such as PDE-5 inhibitors. Consult with your physician before using this product if you are pregnant or nursing, if you are using any prescription medication, or if you have a medical condition. Do not use for more than 8 consecutive weeks.

    Featured Ingredients

    Niacin: Niacin, or vitamin B3, performs 2 functions: metabolism assistance and vasodilation. It carries hydrogen during the electron transport chain, which is a major source of energy in the body. Niacin also relaxes blood vessels and improves nitric oxide creation. This allows for greater workout pumps and nutrient/oxygen transport.

    Beta Alanine: Beta alanine is a non-essential amino acid. Supplementation has been clinically proven to increase athletic performance by lowering body fat percentage and improving lean muscle growth ability. Beta alanine works by stimulating production of carnosine, which improves muscle strength and regeneration.

    Creatine Nitrate: Creatine is one of the most widely-used supplements in the world. It improves strength, muscle growth, and alleviates post-workout fatigue. It is stored in muscle tissue and released during exercise to form ATP, a major energy source. Creatine nitrate is more readily absorbed than any forms of creatine, reducing the effective dose. It also improves nitric oxide production.

    Arginine AKG: Arginine AKD is a combination of the amino acid arginine and alpha-ketoglutaric acid. It acts as both a precursor to nitric oxide production and prevents muscle breakdown. This creates greater intra-workout pumps and reduces post-workout recovery time.

    N-Acetyl L-Tyrosine: This neurotransmitter is used to improve focus during exercise and contribute to muscle growth.

    Caffeine Anhydrous: Caffeine is a staple in pre-workout supplements. It reduces fatigue by binding to adenosine-receptors in the brain and stimulating adrenaline and dopamine production. This effectively increases energy levels. Caffeine anhydrous is just the dehydrated form of caffeine.

    Mucuna Pruriens: This plant extract has been long used in traditional Indian and African medicine. Clinical research shows it’s effective at increase luteinizing hormone and growth hormone levels, both of which contribute to muscle growth. The active compound is L-dopa.

    Q: How do I take this?

    A. Take 1 scoop of Cellucor C4, mixed with 4-6 ounces of water 20-30 minutes before training. Once tolerance has been assessed and you are looking for an additional boost of energy, take one additional serving (1 scoop) with serving taken before training. Do not exceed 2 scoops per day.

    Q: How long does each bottle last?

    A: Each bottle of Cellucor C4 contains 30 days of recommended servings.

    Q: Does this have any stimulants?

    A: Yes, Cellucor C4 contains 150 mg caffeine anhydrous. If you are sensitive to caffeine, begin with a low dose.

    Q: Who can take this product?

    A: This product is intended for use by adults, age 18+. It’s safe for both men and women.
