"MADE FOR THOSE THAT PUSH THE LIMITS AND AREN’T AFRAID TO WORK, SWEAT AND BLEED FOR THEIR NEXT BEST"

Introducing

C4 Ultimate

Ultimate isn’t just a code of conduct… It’s the pursuit to kick ass and take names in the gym. Your crushing hunger to reach your new PR is the very reason why we’ve spent the last few years engineering the most hard-hitting, intense, and focused pre-workout on the market–one that matches your obsession of being better than you were yesterday.*

C4 Ultimate is the most powerful C4 we’ve ever created. It’s not for the weak. It’s not for the weekend warrior. This is for those that don’t have limits in the gym. Those that aren’t afraid to work, sweat, and bleed for their next best. It’s dosed to the brim with the powerful ingredients that your body begs for. You will feel the explosive energy run through your veins as you prep for battle in the gym.*

This maxed-out formula also packs a heavy punch of nootropics, mood enhancers, pump amplifiers and endurance boosters to push you to your ultimate limit. C4 Ultimate will challenge you for one more rep, one more set, and to pick up that heavy dumbbell you’ve been thinking about for weeks.*

I love the taste. Not overbearingly sweet, just right. Mixes well. Has plenty of citrulline malate, beta-alinine, betaine, AKG, and Taurine. Enough said!

I really enjoyed this pre-workout. The pumps were great and the energy was strong but smooth. There was no jitteriness and no tolerance issues. My only critique is that the focus could have been stronger; I would like to see this product have more Alpha-GPC.

Helps me push through my day and grueling work with minimal crash. I can outlast both cardio and heavys. I noticed also less resting times between sets. I did get about as much as 300mg caffeine will give which is plenty. Flavoring and color additives Im not a fan of although flavor was slightly more sour than I expected for an apple-berry, kind of a kick too but pretty decent nontheless.

This pre work out do what is suppose to do. I felt some good pumps, and focus. It's pretty strong for me, I recommend taking some amino acids with it so you don't get dizzy. Or just drink a lot of water.

C4 Ultimate is an amazing pre. I had energy for days in the gym however it is definitely not for late afternoon or night workouts as I would be awake for at least 12 hours after taking it. It mixes very well. I will be reordering cherry limeade once ive completed the 40 serving tub. 1 scoop is extremely strong.

Great pre-workout. I don't take a full scoop. After a week or so, I tried a full scoop and it had me buzzing. 3/4 scoop seems to do the trick for me.

Very Explosive, wakes me right up within 15-20 minutes and I'm ready to hit it hard. Seems as though it helps clear my mind and gives great focus. Definitely works the sweat out of me as well. Highly recommended!

I used to use the C4 Ripped and the energy wasn't great; and after using the Ultimate now, and i find that when I do get the energy burst (which doesn't always happen) it really hits and feels fantastic and makes my workouts a better experience and I get more out of them. The energy doesn't affect me as I would like, but overall, this has been the best Preworkout I've used.

Best supplement out of Cellucor's product line.. Hefty dosage of Nitrosigine, Citrulline, and Betaine while having the stimulant right around my tolerance :) An overall excellent PWO for pump, energy, and focus without the inclusion of Yohimbine, and the flavor is spot on!

  • 8 Cherry Limeade

To begin I've tried many pre workouts including the always hyped up Bnox and none of them could work for me in the aspects of energy, endurance, or focus but C4 ultimate is the kinda pre workout you take when you wanna go as hard as you want. As soon as i started tsking it i instantly noticed a huge jump in energy, and the pumps are amazing on this stuff. The flavoring is great too but just too sweet besides the new raspberry one, but the cherry limeade one tastes just like mtn dew code red, but super sweet, otherwise this stuff is great and i highly recommend it, only con to it is if you take it on an empty stomach you're gonna feel absolutely awful, and the price is a bit much, otherwise buy this stuff!

I received a sample of both the orange mango and strawberry watermelon from cellucor. I just finished using stim free PMP and this puts those pumps to absolute shame. They were rock solid and I kept them for much longer. And coming from a stimulant break this was nice clean energy, hit hard but no adverse effects. My new go to preworkout for sure. Orange mango was by far my favorite flavor. Update: I have now tried all of the flavors, icy blue razz is really good, if you've had anything else icy blue razz you know what you are getting. The cherry limeade is also tastes the cn3 I had in the same flavor. It's very strong so I use more water but tastes really good.
