5.5g creatine system, 3.2g CarnoSyn®, full-strength training focus

Cellucor C4 Ultimate Strength is a pre-workout built for serious strength and output. It goes beyond most basic ones by covering energy, focus, blood flow, endurance, and even some recovery. You feel it right away, but it gets better with steady use over a couple weeks.

The energy and focus part is strong but smart. You get 300mg caffeine anhydrous – that's a solid high dose for staying alert, lifting more, and feeling like the workout's easier. Then they add 50mg Dynamine™ and 10mg TeaCrine®. Dynamine™ makes the energy hit quicker and feel sharper. TeaCrine® keeps it going longer without extra caffeine. There's 1g L-tyrosine to help with brain chemicals during tough workouts. Huperzia serrata extract boosts focus and that mind-muscle link. And 1mg rauwolfia vomitoria adds a little extra kick for folks used to stims.

For pushing through sets, you get exactly 3.2g CarnoSyn® beta-alanine. That's the proven dose to build carnosine in your muscles – carnosine fights the acid buildup that causes burn during intense reps. It's one of the best-backed ingredients here for keeping you going.

On the pump side, it's a team effort. 3g L-citrulline and 3g L-arginine work together like Velox®. Arginine directly boosts nitric oxide for better blood flow. Citrulline helps keep arginine levels up by skipping the liver's first pass.

Key Highlights

  • 300mg Caffeine Anhydrous — this is real high-stim territory, not some weak daily dose. You feel more alert, lift with more power, and the workout doesn't seem as tough from the start.
  • 50mg Dynamine™ + 10mg TeaCrine® — smart move, not just more caffeine. Dynamine™ sharpens how the energy feels and kicks in faster. TeaCrine® stretches it out for a smoother ride.
  • 3.2g CarnoSyn® Beta-Alanine — spot-on clinical dose to ramp up muscle carnosine. Over time, you buffer that burn better and hang in longer on tough sets or high-volume stuff.
  • 4g Creatine Monohydrate — almost a full daily dose of the king of strength supps. It helps recycle energy for explosive moves and builds real gains in power and performance.
  • 1.5g NO3-T® Creatine Nitrate — pulls double duty with creatine for energy and nitrates for blood flow. You get ATP support plus that nitric oxide boost for fuller muscles.
  • 5.5g Total Creatine Compounds — no need to pick between pre-workout and separate creatine. This gives you a meaningful chunk of your daily needs in one scoop.
  • 3g L-Citrulline + 3g L-Arginine — not the max citrulline alone, but a smart combo for nitric oxide. Citrulline keeps arginine going strong, and arginine feeds the pump directly.
  • 200mg PeptiPump® — cool lentil peptide at the right 200mg dose. It works on blood flow in a fresh way, adding to the pump beyond the usual aminos.

Who Is This For?

  • Hypertrophy fans in high-volume phases needing more than buzz. 3.2g CarnoSyn® beta-alanine helps repeat reps, pump stack with citrulline, arginine, creatine nitrate, and PeptiPump® keeps muscles fueled for longer workouts.
  • Strength chasers wanting real progress from their pre. 4g creatine monohydrate, NO3-T® creatine nitrate, and 150mg elevATP® support energy for heavy compounds and repeats.
  • Stim vets bored of 200mg caffeine basics. 300mg base with 50mg Dynamine™, 10mg TeaCrine®, 1g tyrosine, and huperzia builds better energy and focus.
  • Bodybuilders after better mind-muscle in busy blocks. Tyrosine and huperzia sharpen connection, nitric oxide helps sustain pumps on rep work.
  • Hard trainers multiple days a week who need recovery. 2.4g PeptiStrong™ at the studied dose helps preserve muscle and cut fatigue from back-to-back sessions.
  • Folks who like open labels. Every key ingredient has a dose listed, so you judge on real numbers.

How to Use

One serving 20-30 minutes pre-training. Lets caffeine, Dynamine™, TeaCrine®, tyrosine, and huperzia build energy and focus before sets. New to high stims? Half-scoop first to test – 300mg plus extras can feel intense. Mix in 10-16 oz cold water with a shaker for best results; more water eases flavor. Empty stomach for fastest hit, or with light food if stims bug you. Skip stacking with other high-caffeine stuff unless you're tracking total intake. Good with protein, intra carbs for long sessions, or electrolytes if you sweat a lot. No need to cycle creatine or beta-alanine, but maybe pause stims after weeks if tolerance creeps up. Store sealed, cool, and dry to avoid clumping.

What to Expect

Minutes 0-10: energy starts creeping in, especially on an empty stomach. Minutes 10-20: 300mg caffeine and 50mg Dynamine™ really show up, beta-alanine tingles hit, and you're in gym mode. Minutes 20-40: peak time – tyrosine and huperzia sharpen focus, NO stack pumps you up, and you're attacking weights. Minutes 40-90: stays useful without a hard drop, thanks to TeaCrine® and other supports. Days 1-7: energy and focus right away, creatine builds, beta-alanine tingles get normal. Weeks 2-4: CarnoSyn® helps endurance, creatine boosts strength, PeptiStrong™ improves recovery.

Frequently Asked Questions

How much caffeine is in Cellucor C4 Ultimate Strength?

Each full serving contains 300mg caffeine anhydrous. It also includes 50mg Dynamine™ and 10mg TeaCrine®, which are not caffeine but can intensify and extend the overall stimulant feel, so the experience is stronger than a basic 300mg caffeine pre-workout.

Is C4 Ultimate Strength a true strength pre-workout or just a high-stim energy formula?

It is more than a stimulant formula. In addition to the high-stim core, it provides 4g creatine monohydrate, 1.5g NO3-T® creatine nitrate, 3.2g CarnoSyn® beta-alanine, 150mg elevATP®, and 2.4g PeptiStrong™, which gives it real strength, endurance, and recovery intent.

Is the citrulline dose in this formula clinically dosed?

L-citrulline is listed at 3g, which is below the 6-8g range commonly used in standalone citrulline performance studies. However, this formula does not rely on citrulline alone for pump support; it also includes 3g arginine, 1.5g NO3-T® creatine nitrate, and 200mg PeptiPump®.

Why does this formula use both creatine monohydrate and creatine nitrate?

Creatine monohydrate supports phosphocreatine replenishment and long-term strength adaptation, while creatine nitrate adds a nitric oxide-oriented blood-flow angle through its nitrate component. Together they give the formula both ATP support and pump support instead of forcing you to choose one lane.

What does PeptiStrong™ do in a pre-workout?

PeptiStrong™ is a fava bean peptide ingredient included here at 2.4g, the full amount used in emerging human research. It is designed to support muscle recovery, reduce fatigue, and help maintain muscle homeostasis, which makes this pre-workout more useful across a full training week.

Will this make me tingle?

Probably. The 3.2g CarnoSyn® beta-alanine dose commonly causes paresthesia, the harmless pins-and-needles sensation many users feel in the face, ears, or hands before training.

Can beginners use Cellucor C4 Ultimate Strength?

Most beginners should start with a lower-stim pre-workout. This formula contains 300mg caffeine plus Dynamine™, TeaCrine®, huperzia, and rauwolfia, which makes it better suited to experienced users with established stimulant tolerance.

Should I still take separate creatine if I use this?

This formula already provides a substantial creatine contribution with 4g creatine monohydrate plus 1.5g creatine nitrate. Many users will not need extra creatine on training days, though some may still choose to take standalone creatine daily for simple consistency across training and rest days.

How long does the effect last?

Most users feel the energy and focus peak around 20-40 minutes after use, with useful effects continuing well into the session. Because the formula includes TeaCrine® and Dynamine™ alongside caffeine, some users find the stimulation feels more sustained than a simple caffeine-only pre.

Is this formula fully disclosed?

Yes. One of the strengths of C4 Ultimate Strength is that the major actives and their amounts are listed rather than hidden inside a proprietary blend, which makes it much easier to assess against the research.

Life-saver for hands in pain
Size: 5.1 Ounce (Pack of 2)
This is my favorite hand cream. We're in PA and I keep a tube of this by the kitchen sink, in my bedroom, the bathroom, and in my car. I use it all the time and it saves my hands. I discovered it by chance at a store one time and I've tried many products (used to work in Healthcare so was constantly hand-washing). I like O'Keefe's Working Hands all right, and Gold Bond healing hand cream used to be my favorite, but this replaces both. It's so helpful for my 5 year old, too, whose hands get super dry and cracked if we don't keep up with this. It's great stuff. Ever since I discovered it, I haven't been able to find it in stores again. It's always out of stock, so I guess others have figured it out as well!

Holy Grail Moisturizer for Rosacea
Style: Restorative Protective Cream-3.3 Fl Oz
In seeing so many negative reviews I felt compelled to weigh in as this is my favorite moisturizer. I have very dry, menopausal skin. Additionally, I have rosacea which seems to have been a nice gift from said menopause (you can only laugh, right?). It's very common for those of us in our 50's to have a compromised skin barrier and when an issue like rosacea is present, even more so. Because of all this my skin is very intolerant to most moisturizers and nearly all actives (over the last few years I've had to discontinue my retinols and chemical exfoliators). While ingredients like ALA's, petrolatum, mineral oil, parafin/bees wax, and lanolin are well tolerated and known to be quite soothing, they don't hydrate very well as they are more occlusive than moisturizing. Enter this product. Magically, it does both! It's marketed as a protective cream, which again implies occlusive, but it penetrates like no other. Gone is the tight, dry feeling that persisted even when I had a heavy layer of product on my skin (my previous moisturizer was Eucerin Original Healing Cream -- which still has its uses -- because it was the only thing I could put on my skin outside of squalane oil during a flare). Now, no topical can cure rosacea. However, the right product can calm the skin, repair the damaged lipid barrier, and improve its appearance. This moisturizer does just that and it's become my holy grail. Since starting this I've also added in the Cicalfate Serum which has only aided in repairing my skin. Another Avene product that works great for me is the XeraCalm Balm which helps with itching. I use all three of these daily and they've really helped fix the secondary issues that come with rosacea. As for the complaints about it being greasy or too heavy. I can see this not working for people with normal or oily skin (or perhaps only in moderation). But my skin loves the heavier weight and because one of the ways I soothe a flare is to keep a tiny mister bottle on hand and repeatedly spray my face so I have to guard against the drying effects of evaporation. These products are so lipid heavy that I can wet my face all day long without worrying about that, though I do reapply throughout the day. As for the watery consistency issue, I haven't had that problem but it does caution on the packaging not to expose the product to temperatures below 41 degrees F (5 C). I suspect that if it gets too cold either because of the weather or because of whatever warehouse it sat in during transit it will separate. Maybe open the package and before squeezing some out look to see if it has split and then shake it up/message the tube. So, if you have skin like mine don't hesitate to try this product. I'm leaving this absurdly long review for my struggling brothers and sisters out there with rosacea in hopes that it provides some relief! Happy moisturizing, internet strangers. ;)

Possible solution to seperation
Style: Restorative Protective Cream-1.3 Fl Oz
I love this product so much, but, like everyone else the water HEAVILY separated. A lot of water just shot out immediately and as i've used the cream it has felt more and more thick bc of that, shaking the tube or not. POSSIBLE SOLUTION: I actually think the company could salvage this problem by upgrading packaging to a Cosmetic JAR and then customers could take a toothpick and stir if separation has occurred by the time of purchase. I hope to try this with my next tube, just toothpaste squeezed everything out into a nice cosmetic jar and stir the water back into the product. This is such a simple solution that could really solve the product waste. This refreshes my skin, doesn't break me out, and is lovely. I break out so easily, and being middle aged my skin really requires a dense help with moisture. <3

Ordered in spring/summer and it arrived separated too BUT...
Style: Restorative Protective Cream-1.3 Fl Oz
Ok, So I heard great things about this cream and decided to order. I ordered on May 28th and I live on the Gulf Coast of Texas and it is in the low 90s right now. I was worried mine would arrived separated like many others claimed to have gotten theirs, and sadly it did. Warm weather or not, blue water shot out of the tube the minute I squeezed it. Luckily, I read Mia P's review and submerged my tube in warm water (hot water actually straight out of my instant hot water faucet). I left it for about 5 minutes then shook it vigoroously. It seemed to help but was still a bit wonky so I repeated the process again and success! My tube is totally fine now and comes out in a thick, rich, emollient cream as it is supposed to. I will update my review after I use it more but so far I love the way it feels on the skin. It is very thick but spreads nicely and completely absorbs into the skin and leaves no greasy residue which is a big deal because I have oily skin. I purchased this to help with my Retin A uglies (I actually am using Musely with .05% tretinoin) and am hoping it helps with the redness and peeling I am having. I will update my review once I've used it for a while but wanted to post this review as I saw so many people complaining about the separating and just thought I'd mention that you can fix this issue if you have it (and there is a good likely hood that you will). Update: I've been using this for a week now and I am absolutely in love with this cream! It is the most hydrating and healing cream I've ever used. Usually, thicker face creams like this would cause issues for me with acne or clogged pores as I do have oily skin that can break out if I use products with occlusive ingredients, but this one does not. In fact, my skin has never looked better! This is a must-have if you are using Retin-A/Tretinoin and going through the red/peely phase with your skin. The separation that occurred when I first received it has not been a problem and the cream is staying thick and free from any strange liquidy issues after I put it in hot water as mentioned in the first part of my review.
