"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.*

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.

Flavor: 10/10 - I don't give out 10s much unless flavors are amazing. Extra: I have extensive research on Cellucors C4 product line from C4 Extreme, Mass, Ripped, 50x, On the Go, etc now up until Ultimate. C4 Ultimates flavor testing was superb and these flavors are in my top from this brand and product!!! Flavor was amazing, I used a serving scoop in about 8oz of water mixed with crushed ice. I am a huge fan of Cellucors C4 line and this doesn't fail me too the least. C4 mixes well with products from Cellucor but be careful to read the ingredients because too much isn't good. Mixability: 10/10 - no issues at all, no extra flakes give it a good shake and you're good to go. Overall: First off thank you Cellucor for making another excellent product, C4 products work tremendously. Not even that the flavor is a great starting point as well as it tastes amazing. But we are all here for the gainz and getting the boost necessary and routines in, I give this product a thumbs up!!! More Extras: ATP is a source of energy our body created, the more ATP the more our body can do. I won't be going into complete detail as I have learned all about ATP, energy systems, etc in College however one thing I found great about the C4 ULTIMATE is that you won't feel any crash after training/workout. I felt the boost and noticed my training/workout lasted longer than normal. I could've gone even more, and it's hard to find a naturally perfect balance of ingredients in an energy booster, not only does it boost ATP/Energy within the body, the ingredients are a perfect mixture, plus no crash which is what we all need.
