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.

Mixability 9/10: Great mixabilty, started off mixing C4 with 8 oz of water in a magic bullet. I let the magic bullet go for 10 seconds with 2 ice cubes in it and the C4 was completely dissolved within the liquid. Awesome no floaties that's what were looking for. Taste 8.5/10: in 8oz water, Strawberry Margarita really tasted like a watered down Strawberry Margarita. Hit the nail on the head with this flavor profile, I've never seen anything like this before and it will keep customers coming back for more Energy and Focus 8/10: I always drink my pre-workout about 20 minutes before the gym. Shortly after drinking C4 I felt an energy surge and it sustained throughout the entire workout. This was excellent because I usually wake up at 4:15am for my morning workout. I did notice that 1 scoop didn't wake me up enough so i started experimenting with 1 1/2 scoop and also 2 scoops per serving. This was more ideal for me, I felt like I had more energy at the beginning at end of the workout. Strength 8/10: Hit some PR's while on this pre-workout. Felt a great pump throughout the workout and my focus was spot on. Overall 8.5/10: Overall, this is a great product that provided great focus and a great pump throughout my entire workout. Depending on your weight you might have to adjust your dosage from 1 scoop to 1 1/2-2 scoops to feel more of the effects. At the end of my workout it felt as though I was going to tear through my clothes, the pump was that insane. I felt the pump throughout the day and yes the caffeine was much needed to wake my butt up for my morning workouts. I would definitely recommend this new formula to everyone looking for a serious pre-workout supplement to help them maintain a great pump and focus throughout there workout.

I had never tried preworkouts in my life, cause well? I didn't find use for them haha so one day I had some cash, and decided to buy one, I went to buy some Arnold Iron Pump? Worst thing trying preworkout for once. The taste was horrible, and the energy? I wouldn't get one, even tho it claimed to be great...So about a month after trying it, I went to GNC, and all my friends would have C4, I myself had never tried it, at all, so, I thought maybe I give it a try, and at the same time, it does have lots of reviews, good reviews. I bought 2, with the buy one get half off, one from pink lemonade and watermelon. Both flavors are great, I love them, cept I liked pink lemonade better cause it has that little parch taste? like cause of the lemon, so that usually pumps me up, however I usually take 2-3 scoops, cause I have a very high caffeine tolerance. The watermelon flavor is great, both mix well, both taste good. Its been? about roughly a month or two since I've been on them to this date, and I am happy with the results, great results, some nice energy burst, and the energy has helped me gotten more biceps, and shoulders,and chest and well basically cause I've been working on these with the C4, and It does have good results for the time being, great product, look forward to more of their other flavors, maybe Blue Razz, or orange dreamsicle, and some C4 Mass And Ripped, Great product, and is recommended!!! Just look for it at a cheap price lol

Mixability 10/10- the new formula mixed a lot better compared to the previous C4. The power itself was a lot more refine. Taste 10/10- the blue razz was amazing. Compared to the older generation this one tasted a bit more balanced. The older blue razz seemed a bit too hard on the sweetness but it did its job. The new formula has a balance that is not too sweet or tart. Energy 10/10- I felt the energy really well. I was well motivated to start with but this gave me the extra boost I needed during the later sets and reps. Pumps 10/10- as expected of C4 I had good pumps throughout my workouts. Effectiveness 10/10- when I do take it I typically take it on an empty stomach. It hits me a lot faster compared to the older formula. This could possibly be because the power is a lot more refined and that the body absorbs it better.

Let me say that C4 has always been one of my favorite Pre-wo's. through re-formulations and new flavor introductions the quality has never wavered and the new Gen 4 is no different. i got the opportunity to review the Strawberry Margarita flavor and it is delicious! i found my sweet spot at a little less than 2 scoops and like all C4's of the past it gives you everything you could ask for in a Pre...longlasting energy, great focus and superior pumps. this is another solid addition to an already superior product. great job Cellucor...awesomely effective.

First off let's get flavor out of the way. They sent me fruit punch which is my least favorite flavor in supps but Cellucor even made that taste pretty good to a fruit punch hater like me. It isn't too overly sweet and is very refreshing and easy to drink. I can imagine that the other flavors must be top notch coming from Cellucor. 3.5/5 Next is mixibility. Throw 2 scoops in 12oz water in my shaker. Give it a few hard shakes and the powder dissolves and does not leave behind undesired grittiness like some preworkout's do. 4/5 Where this preworkout really shines is in the effects. Energy lasts throughout my workout. No jitters and no crash afterwards. Very clean, smooth energy. What I really like is the pumps that the nitrates provide. I literally felt like my arms were almost swollen to the max on 1 of my high volume days. Also felt amazing pump on chest day as well. The only day I do not use this is on leg day for obvious reasons. 4/5 The original C4 was 1 of the first preworkouts that I used and I must say Cellucor has taken that formula and improved upon it greatly. Energy is better and pumps are even more prevelant. Overall 11.5/15

I didn't think this product could get any better but it has! I tested the Fruit Punch flavor, which I have tried before but this version seemed less tart which was great. It mixed wonderfully in my mixer cup, no grit left at the bottom! I usually drink my preworkout on the way to the gym so it kicks in when I get there but this time it kicked in much faster. I love the new burst of energy! It kept me consistent throughout my workout and had me pumping out some impressive reps. Thank you so much, I will definitely purchase more of this new formula.

This is my review of cellucor c4 Thank you cellucor for providing me with a sample to test. Taste/mixability: 10/10 The flavor I was given was strawberry margarita. Love the taste very nautural taste not too strong or too weak. I normally dose it at 1 1/2 scoops. This stuff mixes very easy to the point were one shake is all it needs. Energy/Focus: 9/10 Energy with this stuff can best be discribed as natural steady as if you got a good nights rest. What I like most about the energy is the consistancy, ive taken a bunch of preworkouts before with mixed results from workout to workout but c4 does it for me every time. it takes about 15 min to feel the effects with very little to no jitteryness. The focus with this stuff is great I feel myself consitrating not only how much I'm lifting but how i'm lifting the weight almost a slowmo effect. Strength/Endurance: 8/10 My strength has definitly improved since taking this. Vascularity/Pump: 5/10 To be honest I was a little disappointed here. At 1 1/2 scoops I simply get very little pump and vein poping. I got a better pump vascularity from 1 level scoop of the old c4 possibly I respond better to fat burning ingredients same with super hd. Side Effects: 7/10 It seems that when I take 1 1/2 scoops My throat gets a little dry and reddness in my face. At one scoop I dont get this but it really doesnt do it for me. Thought: I love the energy I get from this I'm definity lifting more weight than I was with the old c4 but miss the pump definition I got from the old c4 maybe c4 ripped will the answer.

Generation4 C4 Icy Blue Razz flavor taste even better than the previous formulas flavors Formula 10/10: I like this new formula because of the increase in caffeine and the addition of a new ingredient, Teacor. Despite the additional caffeine I don't feel extremely high in energy/jittery; it's just right and makes me feel good. Energy and Focus (10/10): I felt a steady rush of energy. Which, unlike the old formula, was present throughout my entire workout. I haven't felt any sort of crash during my workout or post workout. Yes I've been tired, but it wasn't an energy crash tired it was a muscle are exhausted tired, Overall: Comparing the new and old formulas I must say the new formula has noticeable differences, which I like a lot, and I have had the most excellent workouts. I had high expectations for this new formula and, as usual, Cellucor did not let me down. They definitely exceeded my expectations, as always.

as part of a promotional opportunity i received a tub of the new Gen 4, C4...many thanks to Cellucor for this! ive been a huge fan of C4 for years now so i was especially excited to see how this newest version performed. i got the Strawberry Margarita flavor and following the label, started wtih one scoop in about 6 oz. of water. the product mixed very well and tasted great but honestly, i was a bit disappointed on the overall effects. i usually train for an hour to 1.5 hours and towards the end i found myself dragging. this was quicky remedied by upping the dosage to 1.5 servings prior to my next workout. this dosage is what ive used in the past with C4 and hit the sweet spot again...it gave me ample energy that was clean and smooth, great focus and noticeable pumps. THIS was the C4 that ive come to expect! after 2 weeks of continuous use i didnt notice any reduction in effectiveness or increased tolerance. im very impressed with Gen4 ...its well worthy of the Cellucor and C4 name. nice job!

I love C4. It is the best pre-workout to get you amped up without overdoing it. No jitters, no messy energy, so I'm not spending my entire workout thinking about my heart popping out of my chest. I feel strong, I feel awake, and I feel alert. Not a fan of fruit punch and pink lemonade gets old (especially if you're doing early morning workouts - too strong), BUT Strawberry Marg is an AWESOME flavor. Can't go wrong with that one!

I have been lifting for a few years and have tried all preworkout drinks under the sun usually changing to a new one when I hit the bottom of the tub. That was over a year a ago, my favorite flavor is green apple, but since I've tried them all you can't go bad. Some drinks you build up a tolerance for, not this kind. Love it. All flavors are great, but great focus and energy. Get it!

The new formula is so much better than G3. I take 1 heaping scoop of G4 instead of 3 scoops of G3 which in the end saves me $$$. I have been looking for a solid Pre and this does the job very well. So far I have tried the Pink Lemonade and Green Apple flavors. Both solid. Green apple tastes like a green jolly rancher and Pink Lemonade tastes like your normal Pink lemonade mix. Highly recommend!
