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.

the gasp I guspped 😱
Format: Kindle
This book was so good. I love the world that has been created so far in this story. Addi is a boss and the fact that she is having to hide who she really is from everyone at the academy yet also being able to stand her ground and not be bullied into anything just shows how strong she really is. She doesn’t take anything lying down and even if it makes the target bigger on her she sticks to what she believes is right. Raiden, Brody, Cassian and Kryll all seem to have a pull towards Addi but with them all competing against each other in the hopes to become the next heir they try every way they can think to get her out of their heads and out of their way. I love the push and pull between Addi and the guys. They have this electric chemistry that makes them want to hate each other but fine that they don’t want to pull away from each other. I really can’t stand the girls who are always trying to start stuff with Addi just because the guys show interest and they feel like they have a right to.That also goes for Cassians dad and the dean and her elitist self 🙄 But that ending had me GASPING 😱 like I knew he was a crap person but I didn’t expect that at all. I need the next book ASAP 5/5⭐️’s 2.5/5🌶️’s

It's okay... Needs something
Format: Kindle
This author has potential but her books tend to follow the same formula on plot that I usually DNF. Plot - Girl has goal, boys determined to chase her off (usually for dumb reason), mean girls, and before book 1 is done, guys enamoured with FMC cuz she shiny and pretty. It gets boring fast. This one is an improvement, I completed it and for the most part, I liked it. However, I hate when the FMC tells herself to stay focused, thinks logical, looks like she will be a strong FMC, and in the next chapter succumbing to the MMCs due to lust. Why? Especially, when there hasn't been much conversation between them to justify that level of attraction or connection. Don't get me wrong, I love spice, just make it make sense, its giving fast burn and if that's the case, write 1 book. Second issue, I love bully romances, I want to hate the MMCs, than I want the author to some how make me love them. Chefs kiss 😘 So, I was draw to this book bc of that theme...Not getting it here. Technically, they are sort of mean but this ain't it. One is mean but for a stupid reason... he doesn't need to be distracted by his attraction 🙄, he just looks weak to not be able to control that, just saying. The other two are just followers and don't really care enough about her to bully her. Last one, doesn't bully her, he's just trying to get in her pants. Lastly, we are to believe MMcs are baddies... cruel, ruthless, ambitious, and dangerous... please show me that in the next book cuz saw none of that in this one. That goes for the FMC, the men shouldn't be able to get over her all the dang time, definitely not for someone who has been training their whole life to take back their crown! Third issue, the academy concept is falling flat for me. That needs some world building, development... Something! Its just reading filler space to me. The book description reads like this school is designed to weed out the weak by difficult competitive challenges so your left with one strong leader who will take the throne. Nah... more like charm school. All in all, it follows the same formula as her other "academy" books but slightly better... Not sure if that's true, or maybe I was just determined to finish one of her books for once.

A good start to the story
Format: Kindle
This was definitely entertaining, and the cliffhanger left me curious to see what happens next. Addi is definitely a bad ass and she has to prove herself Day in and Day out because of what she is. I love that. She never cowards and always rises to a challenge. She doesn’t let anyone push her and she always has a comeback for any prejudice thing said to her. I’m looking for more from the guys cause so far I’m honestly unimpressed. They definitely have some growth and helping within these next few books I’ll see that growth and like them a little more.

OUTSTANDING
Format: Kindle
This was very, very good. The world is vast and characters are complex. There is a good plot with a whole lot going on. This is well written. Good twists and turns and some heart breaking moments. You will love these characters, they have heart and loyalty. I am hoping that there will be several more books. We've yet to see anything from the Sea Court but only a mention of them here and there. The Wood Court was given a quick couple of scenes, and only as far as some warriors, we've yet to enter their court and the Shadow Court, I'm not sure if they will be a force for good or bad, but they definitely will play a much bigger role moving forward. This is primarily the Ice and Air Courts. Told in multiple views, which I loved, it gives you a chance to see things from different eyes. There's alot of political maneuvering and deception. I loved it and will pick up the next book as it becomes available. If you like The Fae and the courts, you should love this. I think the author has mucn in store for us.
