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.

Very bad
This guys are just an eye wash, they do not cover anything but will charge you. I bought Hand Blender and it broke in couple of months and I took 3 year protection from Asurion. When I contacted them about the issue, they said it is not started, go to manufacturer. I reached out to Amazon and they replaced it for me. Now again it broke. I reached out to asurion again. Now they say it is not contract. what is the point of having protection. Waste of time and money. I will not recommend this to anyone. This is a fraud protection.

Simple and not Drama claim process.
’ve had Asurion coverage for a couple of years and never needed to use it until recently, when my pool salt cell (less than two years old) stopped working. I had purchased it with an Asurion protection plan, so I contacted them to start a claim. The process was simple and straightforward to follow. In the end, they honored the plan and covered the cost of my salt cell based on the value when I originally bought it. They issued me a gift card that I could use on Amazon for that amount. While prices have gone up and a new cell now costs about $200 more, it was still definitely worth having the coverage. Overall, I’m satisfied with how the claim was handled.

Love this protection plan
Quick and easy. My daughter's cracked her screen on her phone, as soon as it happened I went on the app, filed the claim. Ten minutes later I received the email with the shipping lable. The following day I dropped the phone off at ups and 4 hours later I received the digital gift card. Ive filed several claims since getting the protection plan and with four kids its definitelysomething im glad to have especially since i dont have to buy a protectionplan for each item now. I have filed claims for electric scooter the stoped working for no reason, my son's phone stopped charging, my oldest daughter cracked her phone screen, my son's video game controllers up and died and each time it was quick and easy and no fuss

Don't waste your money - these people will not help you
On March 9th 2024, I purchased a MCombo Lift Chair costing $785. On the same day, through the same Amazon account (my PERSONAL account since I also have a business account), I purchased an Asurion Complete Protect policy at the cost of $16.99 per month plus taxes. About one month ago, a problem arose with the chair that required me to make a claim using the "Complete Protect" policy that I had purchased for that very item. The claim was initiated on January 1st, 2025 - On January 3rd, I received an email asking me for photographs showing the damage for which I was making a claim. I sent those photographs via email to the address provided on January 6th. On January 27th, having not received ANY response from Asurion, I contacted them via phone and was told that my purchase had been made with a business account, that it was being used for business purposes, and was therefore not covered. I assured the Asurion Representative that it was most certainly not a business use, and that the chair that I was claiming for had been purchased because I had extensive shoulder surgery done that made it impossible to get in and out of bed. After speaking (unsuccessfully) with the Asurion Rep, I then contacted Amazon Customer Service. I spoke with an Amazon Customer Service Representative on the phone who confirmed that I had in fact used my personal account to purchase the chair and the Asurion Complete Protect policy. That representative went on to send a message to Asurion on my behalf confirming that the purchase was for personal use and not business use. Asurion responded, asking me to call them with the order number for the Asurion purchase. The number I gave was the exact same order number on my order history, however, the Asurion Rep could not find it. I was finally able to discover that the order number in Asurion's system was entirely different and isn't even in the same format as an Amazon order number. Upon the Asurion representative finding my plan, she informed me that the chair was listed as being purchased for business use (despite Amazon confirming that it was NOT) but that I should give them "a couple of business days" to resolve the issue. Five business days later, still no response and so I called them again (Yesterday - February 1st 2025)... Lo and behold, I got the same crap yet again... the purchase was listed as business use and was therefore being denied, but she promised to remove the business use commentary and put the claim through again. Today, February 2nd, I called Amazon yet again to escalate and had to call THREE times because the first two calls resulted in me finally being connected to an Asurion representative (two different reps) and each time, the Asurion representative hung up the phone as soon as my name was mentioned. It has become clear to me that the Asurion "Complete Protect" policy is a SCAM - they will NOT take care of your issue, regardless of how long you've been paying. I have been paying every month since March 9th last year - so they've received over $170 from me thus far, with zero other claims, and if I am able to cancel right now, I will only receive $16.99 back. All I want, is the chair that I purchased the policy for coverage of, to be repaired or replaced. Asurion are NOT helping, and are actively avoiding contact. At this point, I am considering legal action against Asurion for fraud - perhaps even a Class Action. I'll wait and see if my issue gets resolved within the next 10 days or so.
