"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 took C4 Ultimate after a week of absolutely no pwo. I've been taking most of my trains to the mountains and don't take any for outdoor activities. I took ultimate right before leg day. I had been very tired all day. Here is what I concluded. The Strawberry watermelon tasted like a jolly rancher as Ive seen others state. It kicked in fairly quickly, about 10 minutes. First thing I noticed I was the laser focus. Then I started adding reps and weight to my presses and super setting my squats with no breaks in between. I was pacing back and forth waiting for my husband to finish his sets. We had to leave after an hour 15 minutes but I was NOT ready to leave! Plan on a long sesh with this stuff. The Ultimate was great! It was refreshing. Not like the rest. This truly is the ultimate on all sides! Nice job cellucor!!!!

I've been training for a solid 6 (almost 7) years now. With that being said, I've had just about any "newest and greatest" pre-workout there is. Every year some company will make a new pre that claims to be the biggest and best in this large market. As of date, Cellucor has been one of the very few that live up to it's claims. Pumps? Check. Energy? Check. Veins? Check. Flavor matches taste? Check. Easy to mix? Check. Leaves you wanting more? CHECK! I can say this is true as I kept my training and diet the exact same. The only difference? I used this pre-workout. This pre-workout left me wanting more. This is the the pre-workout of 2017 that will make you want to lift ALL of the weights!

I was given the chance to sample some of Cellucor's well known C4 products in order to review them here on the site. For me, I've never really used pre-workout so it was interesting to try a sampling at least. Like many others, I have a similar opinion so this won't come off as much of a surprise. This flavor is good. While I don't know what is exactly different between their different lines of preworkout (original, ripped, extreme, ultimate, etc), when it comes to taste this one is spot on. I can't quite feel the difference between the ultimate and the extreme but did manage to get in a good workout. The day I tried this one, I had upper body and cardio. Not one rep max type but back into things as I started getting ready for my summer prep. It was also a long day since I went out late that night so was good to have energy throughout. Flavor 9/10 Mixability 8/10 Results 8/10 One of the top flavors for me and if I had funds and really wanted a pre-workout, this is one I'd consider buying.

My favorite of the C4 variations.. well deserving of being on the first page upon searching Cellucor. Enjoyed the addition of Citrulline and Nitrosigine for some massive pumps, and the flavor had no flaws :)
