C4 EXTREME ENERGY

All pre-workouts are not born equal. Some provide a little energy, some provide the kick you need to build mass, some help you lose it. But what you need is energy. Boundless energy. Your intensity comes after an extreme jolt, so we’ve added the most stimulating, caffeine-loaded pre-workout supplement to our C4 ID Series. C4 Extreme Energy is made for your passion, steady drive and unbroken commitment to your workouts.

If you find yourself drinking cup after cup of coffee throughout the day and built your caffeine tolerance above the rest, C4 Extreme Energy is made for you.

C4 Extreme Energy is the next step for those who want that extra rush. Its formula features more than twice as much caffeine, more focus and more endurance than C4 Original. C4 Extreme Energy isn’t for the casual gym goer; it’s for those of you who want to explode through their PRs over and over and over again. We know that for some, just a little bit of energy isn’t enough. C4 Extreme Energy is here to help you get up and go, rising to any challenge.

I have been using C4 50X until it was discontinued and C4 extreme energy replaced it. Personally, I prefer the 50X over the new brand. 50X didnt make me sweat like I do with the extreme energy. By the time I have finished my workout I am soaked. I do get a good workout but its no different than the old 50X. The tingles are less with the new brand even though it has more Beta-Alanine than the 50X?!?!?! I still rate this pretty high because I do have great workouts with this, but I hate being soaked with sweat. 50X was the best.

Flavor: 10/10 - I don't give out 10s much unless but these flavors were amazing and another reason I love Cellucor. Extra: I have extensive research on Cellucors C4 product line from C4 extreme, Mass, Ripped, 50x, On the Go, Ultimate. Neuro, Zero and now EXTREME ENERGY. C4 EXTREME ENERGY flavor testing was superb and both of these flavors are in my top from this brand and product!!! Flavors are 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.

I LOVE cellucor C4, and they boosted it with EXTREME ENERGY!! Exactly what the dr. Ordered. When I'm getting ready to get my GAINS I always down a c4 pre workout to boost my workout. If you are looking for maximum results with a great taste, then I suggest the Cherry Limeade C4 Extreme Energy.
