C4

The Edge...

The greatest competitors in the world all have one thing in common—they’re driven by the ability to push limits. They don’t back down from a challenge, and they know that the only way to reach higher is to keep moving forward. 

For those of you who continue to set goals and crush them, we've created the next level of C4.

What's in C4?

C4 was the blast heard around the world when it launched in 2011. It’s helped gym junkies, weekend warriors, and competitive athletes everywhere rise to become their own versions of legendary.

The Fourth Generation C4 is the next level of innovation and refinement. Its formula is now more dialed in, more potent, and includes the breakthrough ingredient, TeaCor™ for improved energy that comes on quickly and lasts longer.*

The C4 formula includes ingredients that help promote energy, pumps and performance.*

Beta Alanine: An amino acid that supports muscular endurance. Beta Alanine produces a tingly sensation throughout the body that lets you know it's working.

Creatine Nitrate: Creatine bound to Nitrate. Creatine Nitrate produces two desirable effects on performance: Creatine for strength and Nitrate for pumps.*

N-Acetyl L-Tyrosine: It is a core part of the essential energy blend. It helps support peak mental and physical performance.*

Caffeine: A popular and proven source for energy.*

We Know Flavors

Fruit Punch, Icy Blue Razz, Watermelon and many more… We appreciate the art of creating flavors that people love. You should enjoy every sip of your pre-workout. C4 will make your workout that much sweeter. 

Experience Explosive Workouts*

The taste of C4 when you take a sip. The tingly sensation you feel as it travels through your body. The surge of motivation that hits you at the perfect moment-- right before you’re about to hit your workout...the only word to describe it is explosive.

Everything you love about your favorite pre-workout lives on, and the next chapter of your most epic workouts has just begun. 

How do I take C4?

It is recommended to take one serving of C4, mixed with 4-6 oz of water, 20-30 minutes prior to training. Once your tolerance has been assessed, you may take an additional scoop, with an additional 4-6 oz of water, 20-30 minutes prior to training.

Why doesn’t C4 have specific cycling instructions?

When the reformulation of the Generation 4 C4 products took place, it was determined that the product did not required a specific cycle time for the product to be the most effective. However, in regards to products that contain stimulatory ingredients, we recommend to use the product for up to 8 weeks, then discontinue use for 2-4 weeks. Over time, your body could build up a tolerance for ingredients that support energy. By discontinuing use, you allow your body to reset those tolerances.

How many servings of C4 can I take per day?

We recommend to not exceed 2 servings per day. If your workout schedule requires two workouts, we recommend to only use one serving of C4 per workout. To not exceed 2 servings in a 24 hour period.

Why does my skin have an itchy/tingling feeling after taking C4?

The C4 family of products are formulated with the amino acid Beta Alanine, which supports muscular endurance, and often has a tingling/itching effect experienced by users about 10-20 minutes after consuming the product.

Are there any flavors that are naturally colored?

Yes, the Pink Lemonade flavor is naturally colored by the ingredient Beet Root. Beet Root is the root of the purple colored garden beet, and because of its vibrant color, beets are often used for natural coloring or dyes.

How much caffeine does C4 have per serving?

C4 contains 150mg of caffeine per serving.

I am currently taking a PDE-5 medication for ED, why is there a warning on the label not to take this?

Because of the nitrate's ability to relax the walls of the blood vessels to promote increased blood flow, nitrates are frequently included in men’s sexual health products. Taking nitrate ingredients and PDE-5 inhibitors at a similar time could cause an unsafe drop in blood pressure. Because some dietary ingredients also act as PDE inhibitors, please consult a licensed qualified health care professional before taking this product with any dietary supplement, product, or medication.

Why was Synephrine (Advantra Z) removed from the Generation 4 C4 formulation?

Based on valuable feedback from our customers, we made the decision to remove that particular ingredient and modify the formulation to be even more effective than before.

Can I stack other Cellucor products with C4?

You certainly can, however you want to make sure to not take in an excess of nitrate ingredients, nor stack stimulant based products such as pre-workout and weight loss products. One stimulant based product to be used at a time (C4 Family of products, SuperHD, D4 Thermal Shock) Products with higher concentration of nitrate based ingredients such as the C4 family, NO3, and CN3 are recommended to not be used together.

I was given a free sample of icy blue razz C4 to test out the new formula, so first and foremost, THANK YOU! I have nothing bad to say about this new formula. I mix it with 8 oz. water and chug it about 15 minutes before I hit the weights. The energy really is explosive. The increase in caffeine and addition of Teacor really give you that sustained energy you need for any type of workout you're into. The boost in caffeine was perfect, not so much that I'm crawling out of my skin but you really feel it. As far as pump goes, I've never felt such a pump as I do with this new formula. My muscles feel like they're going to tear right out of the skin, it's really awesome. The taste is good, as always. Icy blue razz if my favorite so I really lucked out getting sent that flavor! You guys really out did yourselves this time, thanks again!

This is my first time ever using a Preworkout and it was AMAZING. Blue Razz and Pink Lemonade are really good. Before I would get tired quickly after doing a few workouts, but with this I was able to do a more intense workout in less time. I would recommend this to any and everyone wanting that extra push in the gym.

It's Cellucor, so you know it is a quality product either way. As an EMT, I trust their products to give me the edge I need. -Flavor: Icy Blue Razz -Taste Rating: 9/10, I personally prefer pink lemonade. -Mixability: mixed perfectly with 600mL of room temp to cool water, no chunks. -Dosing: 1 scoop 20mins prior to workout. Once I got to the gym, I would take another 1/2 scoop before I started and put another 1/2 scoop in my water to drink intraworkout. Every time I took the new C4, I ALWAYS got that tingly, no jitters, amp up I love. If you want to take your workouts to the next, next level don't waste your time elsewhere, grab a can of the new C4 and rock on!

Watermelon is an amazing flavor. I have been trying many different brands of pre-workout over the last 3 years and some did nothing for me while some were giving me PVC's and kept me tachycardic for up to 6 hours after my workouts. C4 really gives me a solid edge on my workouts and allows me to stay focused and push myself to go further and get those extra reps. I am hooked on this stuff and am now making my way to the whey protein to consider switching that as well! Stay Classy Cellucor!

C4 G4 REVIEW Well, it certainly has been a while since I did a review, but what better way to come back strong than by reviewing the ALL NEW AND IMPROVED pre workout juggernaut supplement: 4th Gen C4 Extreme by Cellucor! I would like to give the good folks at Cellucor a tremendous shout out for giving me the opportunity to test drive one of the start products in their NEW 4th Generation Cellucor Lineup! For those of you who do not know, C4 by Cellucor is a Pre Workout Supplement (I’m sure most of you have heard of by now) that has been at the top of the charts for several years. It has been my go-to pre workout supplement of choice since 2009. I have used a multitude of pre workout supplements over the years, with C4 by Cellucor being the most consistent product used for my training. This review of the NEW C4 will cover the following: - Taste/Flavor - Mix ability - Energy - Mental Focus - Stamina/Endurance - Pumps/Vascularity - Final Comments/Overall Rating I just want to make VERY CLEAR right off the bat that this review is from my own personal experience and use with the new 4th Generation C4. What you read about my experiences and opinions on this product are MY OWN. What I have experienced with this product could very well differ from the experiences you have had or will have with this product. This is simply what I experienced with the product and should be used as some useful information and insight on what you could expect should you decide to use this product. Let’s get started. Taste/Flavor: Cellucor to me is synonymous with GREAT FLAVOR. I went into this assuming that little to no tweaking was done to the flavor formula as it was not mentioned as being one of the components that was improved with the 4th Generation version. The flavor I got to test drive was watermelon, and OH MY GOODNESS! I have reviewed Cellucor watermelon-flavored products before as having a “Jolly Rancher Watermelon” like flavor, and with the 4th Gen Watermelon I was reminded of that vivid and SHARP taste! I don’t know if it was because I had about a solid week of no pre workout supplement prior to taking the new G4 C4, but I felt that the flavor was very sharp, depending on the amount of water used. Over the course of two weeks I decided to vary the dosage as well as the ounces of water used to test the amount of watermelon flavor and its potency depending on how much was used. The following is the list of my personal findings with flavor and dosage: - 1 scoop & 6oz: Flavor is sharp, slight tartness pairs with the sweet jolly rancher flavor - 1 scoop & 4oz: Flavor is sharp, tartness VERY present that pairs with the sweet jolly rancher flavor - 1 scoop & 10oz: Flavor is still very much present, overall sweetness and taste is slightly muted - 1 scoop & 12oz: Flavor is still there, sweetness is still slightly present, no tartness present - 1.25 scoop & 6oz: Flavor is QUITE SHARP, Tartness very strong (which I like) & sweetness strong - 1.5 scoop & 10oz: Flavor is INTENSE, Tartness very present and commanding & sweetness strong - 2 Scoop & 10oz: HEAVEN. Tastes as if a bunch of Watermelon Jolly Ranchers were melted and consumed. A tasty and flavorful PUNCH IN THE MOUTH. Basically, if you stay in the 4oz to 10oz range with 1 scoop of G4 C4, you will notice a pleasant and strong flavor. I have found this to be the norm with EVERY flavor of C4 that I have tried (I have tried all of the 3rd generation flavors with the exception of Mojito as well as Orange Dreamsicle). This is me personally, but watermelon is one of my personal favorites when it comes to the various flavors Cellucor offers, so I am a little biased in this regard. DEFINITELY a Must have if you are a watermelon fanatic! RATING: 10/10 (Not sure if they improved the flavor formula, but I thought this was just ridiculously good!) Mix ability: If you are like me, and have taken numerous products by Cellucor, then you already know that with the exception of M5-RELOADED (Mass Builder Supplement), all of the brand’s products mix extremely well and with little effort. Whether I mixed 1 scoop, 1.25 scoop, 1.5 scoop, or even the INSANE 2 scoops, the new 4th Generation C4 mixes very well ease. Even if you were to only use 4-6oz with 1.5 or 2 scoops, the powder blends very evenly within seconds! I used my new Vortex Blender 2.0 bottle for every dosage of G4 C4 that I took. I used it with the motorized attachment for power blending and I also used it without and simply swirled the mixture by hand. Both methods were effective and both yielded no particles or “floaters” as I like to call them, at the top of the liquid. IF, and I mean IF, you leave the blended mixture alone for a minute or two, there will be a little bit of particle settling at the bottom. This really is not a big deal to me, and should not be a big deal to you, since the particles are so small you will not notice them or feel them when you consume the mixture. Other than that, G4 C4 mixes EXTREMELY well with no clumping, muss or fuss! RATING: 10/10 (maybe a 9.5 if I felt the small particle settling at the bottom was an issue. But it’s not.) Energy: Okay. Now down to what really matters: Does this product even work?! As far as my overall energy during my workouts while consuming this, I will go so far as to say that it definitely made a difference in my overall MAXIMAL energy. What I mean by this is that I always have energy when I train, largely due to the fact that I do not typically train in a fasted state (just my personal preference, and my body performs better with food in my system). HOWEVER, when I test drove the new C4 I did have several workouts in which I did not have any food in my system. I did not purposely plan this for the sake of seeing how my body responded, that’s just how it happened. The surge of energy from this product definitely hit me on the days I was in a fasted state, but that is how the 3rd Gen C4 hit me too. Back to my MAXIMAL energy. This product really thrived in the aspect of MAINTAINING the energy I had in addition to the energy that the product gave me throughout the ENTIRE WORKOUT. YES, I felt ready to spend another 2 hours in the gym at the end of each of my workouts over these past two weeks. The addition of the “TeaCor” to the energy formula in this 4th Gen C4 I believe really plays a part in keeping the energy I have during my training both SUSTAINED and CONSTANT. I ended each and every workout strong and always had extra energy after the workout, which for some of my late night workouts was probably not a good thing as I had to wait a while to get to sleep (even though I am a night owl at heart). This energy (with the exception of 2 scoops, which made me feel like I could break doors in half) was very smooth. I prefer products that do not load up on the caffeine (talking 200+ mg amounts here), but rather utilize other ingredients to help assist with providing long, sustained energy, and G4 C4 DELIVERED in this regard. I would say the energy is still comparable to the 3rd Gen C4, but from my experience with this new 4th Gen, there is definitely a noticeable difference in the energy following me to the very end of each workout. RATING: 10/10 (I believe the new addition of TeaCor to the formula definitely plays a part in bringing out a more sustained and calm energy with this product) Mental Focus: Here is the one area where I was not really sure if the new C4 brought upon an improved mental focus for me. I have learned to really enter my own zone in terms of mental focus and fortitude when it comes to my training now, so I do not have a need to rely on a product to give me that “mental edge.” The only product that really helped “lock in” my mental focus and mood was the improved P6 BLACK, not a pre workout. I believe that the TeaCor and the Velvet Bean extract in the product formula could have helped to keep my energy sustained, which in turn could have also kept my mental focus steady and strong. In my fasted state workouts I did not feel mentally drained, so I believe that the new C4 could have played a role in my mental focus. Rating: 7.5/10 (I rated this low because I would need more time and experimentation to really assess the effect on my mental focus this product really could have) Stamina/Endurance: My overall stamina and endurance really goes hand in hand with my overall energy while I have been taking the new C4. My training program has heavy, low rep, compound exercises, along with days where I have reps that range from 8 all the way up to 20. These workouts have left me sore, but not once during my workouts did I feel as if I had to stop, give up, take a longer break, etc. G4 C4 really kept me going and going and going, energizer bunny style. When I took 1.5 scoop and 2 scoops as dosages, I was almost ready to jump into the next set (even on my heavy weight, low rep exercises) and had to remind myself to rest a little bit longer and not jump the gun! No doubt about it, my stamina and endurance was sustained and never dropped or quit before my training was completed. RATING: 10/10 (I kept going and going and going and going and felt as if I could have spent two more hours in the gym after each and every workout) Pumps/Vascularity: Right now, I’m fat. Okay, Okay. I’m not obese or mega overweight, but I have accumulated quite a bit of fat in my midsection as I have been basically dirty bulking for the past several months. My leanness is where my vascularity really shines, although my shoulders and upper pecs always seem to show the veins. So in terms of overall vascularity, I really did not notice any crazy roadmaps of veins or veins in places I didn’t know I had veins, but I would definitely say “THE PUMPS WERE REAL.” I felt my body pumped up and tight whether it was an upper body or lower body day. The pump lasted about 30 – 60 min after my workout, but then soon diminished. RATING: 8/10 (Did not do much for vascularity, but overall pumps were noticeably felt EVERY workout) Additional comments/overall rating: Does the NEW C4 live up to the hype?! I would say it is not hype, but the improvements made to the formula are certainly noticeable. This isn’t a NEW product in the sense that it is a completely new product in terms of formula, taste, effect, rather, it is an IMPROVED product than its predecessor. Personally, I would need more time to really test the boundaries of my “tolerance” to the product in order to assess the effectiveness of the TeaCor that was added to the formula. I LOVED the sustained energy that it gave me, the flavor and taste that quenched me, and the pumps that were very much felt with every workout. This product is DEFINITELY worth picking up, and is reasonably priced for what it provides. Cellucor definitely took the time and effort to bring an IMPROVED formula and an IMPROVED product! OVERALL RATING: 9.35/10

I've ordered so much of the Strawberry Margarita flavor! When I first tried it, I thought it tasted like sweat with a strawberry-sweet aftertaste, but I didn't hate it. I've been using this for 10 weeks now (4 weeks on, 1 off), and it definitely gives me that focus I need at the end of the day for my workouts. I don't feel a crash of energy, and if I have to have a cup of coffee in the morning (which is maybe once every two weeks), I don't experience any adverse effects. I love this product a bunch!

Watermelon flavor tastes exactly like watermelon jolly ranchers. The energy is decent. One scoop probably isn't enough for people who have decreased sensitivity to pre-workouts or stimulants. All in all this is by far the best tasting pre-workout powder I've ever tried and I'd recommend it to people looking for a boost of energy, especially if you've never tried pre-workouts before.

️Mixibility: I feel as though with previous generations of C4 some product would always clump at the bottom of my shaker cup. This new formulation is a much finer powder and mixed up perfectly In a glass with a spoon, no shaker needed. Taste: In previous versions of c4 they have always tasted good to me, a little on the sweet side and most were pretty tart. Fruit punch in other versions was usually pretty tart for me. This new version tastes sweet like usual minus the tartness which makes it much more enjoyable. Sometimes I like to mix it with extra water and continue sipping on it throughout my workout because it tastes so good. Energy & Focus: This procurement has always given me tremendous energy & focus. I was skeptical that a better formula could be made. I appreciate That The caffeine & beta alanine levels were both increased. I'm glad the N-Acetyl-l-tyrosine stayed in the formula since I can really tell extra mental clarity from it. I'm a big fan of removing bitter orange & yohimbe and replacing with a cutting edge novel compound like teacor. TeaCor seems to give as good if not better energy/focus than the other stimulants minus the unwanted side effects. Typically I would use 3 scoops of c4. The tweaked formula has allowed me to cut back to 2 scoops which adds extra value to the product. I used this product ever day for 2 weeks and noticed no tolerance. Strength: I'm currently cutting so calories are lowered, cardio is increased, & c4 was the only supplement I was using during the 2 week time frame. Even while cutting I was able to maintain my strength, & it even increased on some lifts Vascularity: This is one of my favorite parts of c4. I've been using it for years & it always delivers some of the best pumps possible. I think Cellucor struck gold when they decided to use creatine nitrate in their preworkout & the addition of arginine akg allows it to last even longer in your body. I notice the pump regardless of how much product I use which really is a testament to how potent the creatine nitrate is. I've even found myself taking a scoop of c4 on nights I go out in order to give me energy/focus/& pumps lol Formula: I've been a loyal fan of c4 ever since it was first released a few years back. I'm extremely happy Cellucor has continued to use the same foundation for the formula while only tweaking very minor aspects of the formula. I think this is a more stream lined & consistent product that would work excellent for men, women, power lifters, cross fitters, & your average gym rat.

Fruit punch tastes sweet, minus the usual tart. I like to mix some extra water and enjoy sipping on it once my workout begins since it tastes so good. Almost identical to fruit punch Hi-c Energy & Focus: This product has always given me tremendous energy & focus. I was skeptical that a better formula could be made. I appreciate that the caffeine & beta alanine levels were both increased. I'm glad the N-Acetyl-L-tyrosine stayed in the formula since I can really feel some extra mental clarity from it. I extremely dislike yohimbe & bitter orange so I'm very excited those ingredients were removed & replaced with cutting edge compounds like TeaCor. TeaCor seems to give me just as much energy & focus minus the unwanted side effects such as anxiety, headaches, or a crash. Typically I would use 3 scoops of c4 pre-workout, with the new formula 2 scoops give me the perfect boost. Strength: I'm currently cutting so calories are currently lowered and cardio is increased. C4 was the on;y supplement I was using for the length of the review. Even while cutting I was able to maintain & even increase strength slightly on some exercises. Vascularity: This is one of my favorite parts of c4. I've been using it for years and it has always delivered one of the best pumps possible. I think Cellucor struck gold when they decided to include creatine nitrate in their pre-workout. Arginine AKG compliments the formula well and helps facilitate a perpetual pump. I notice a pump regardless of how much product I use which is a true testament to the potency of the raw ingredients. I've even found myself taking a scoop of c4 on nights I go out in order to give me energy/focus/ & to look pumped up lol. Formula: I've been a loyal fan of Cellucors for a few years now. I've tried every incarnation of C4 & it keeps getting better. So many times companies will make "improvements" to their products when the only thing they changed was removing ingredients that worked & replacing with cheaper less effective alternatives. The core foundation of c4 remains unchanged, things were only slightly tweaked which is great since cellucor already had a top notch product on their hands.

This is a nice improvement on the old formula. The older version of C4 seemed to be a hit or miss for me. I have had nothing but good workouts with the G4 version. 1 scoop gives me the alertness and extra boost I need to get started on my workouts but for me 1.5-2 scoops really shines. The full dosage of beta-alanine in 2 scoops really helps to power you through your workouts. Not sure why but C4 seems to give me a lot more tingles than other products containing the same amount of BA. For me that's a good thing cause it tells me its working. Tastes and mixes just fine, the strawberry margarita flavor was nice and refreshing.
