"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.*

This was overall a fantastic pre! I have a lower caffeine tolerance so the 300mg is a little too much for my liking. I took half a scoop and it got me through my training and then some! If you like caffeine and all the tingles, this is for you. The apple berry flavor was not my favorite but defintely wasn't bad!

C4 is most peoples' first pre-workout, helps you crush your first few workouts, leaves you feeling tingly, makes you feel good. After a while you want more and you move upmarket, you forget about your good old buddy, C4. C4 Ultimate is Cellucor's attempt to re-capture that market with a mostly-disclosed label and huge doses of effective ingredients - 6g Citrulline, 300mg caffeine, 3.2mg CarnoSyn, Theacrine, and more. I work out at night and Theacrine doesn't always agree with me as a result due to its 8+ hour half-life (contrary to popular belief, I do sleep) but for morning and afternoon workouts, it's a worthy entry into the market and stands toe to toe with some of the best preworkouts available right now. Welcome back, buddy.

i really liked Ultimate alot. this is touted as the most powerful C4 yet, but for me, the Extreme Energy was stronger. i thought the Ultimate was great...energy, pumps and endurance were all strong and focus was was laserlike! yeah, this was definitely one of my top 3 C4s...great job with this.

Easily a top tier pre workout. The majority of the ingredients are clinically dosed and you only need one scoop. Pumps were great with multiple clinically dosed pump ingredients, as was strength with both betaine and creatine included. A great dose of beta alanine for endurance as well.
