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 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.

Believe it or not, this was my first time trying C4! I consider myself to be a mild stim junkie, but I do have to moderate my pre workout caffeine if I want to be able to drink my coffee afterwards! I did 1/2 scoop about 30 minutes before the gym. This product does have a little bit of creatine, arginine and beta-alanine in it, but I mostly felt the caffeine and the caffeine like ingredients. Energy was good, but like I said, a bit caffeine heavy for my preference in a PWO. However, that is the marketing for this specific product so it does what it says! Mixed easily in my shaker bottle, and tasted delicious. The only thing I would change is the "Energy Blend" - it makes it hard to decipher how much stimulant you're actually getting, but the packaging says 300 grams Caffeine so I'll go with that. Overall, 7/10, recommended for stim junkies! I cold also see myself drinking this instead of coffee on those hot summer days.

This pre kicked in about 5 min of me taking it and gave me the right amount of energy I needed to get through my workouts. The taste is good and mixes well. Highly recommended.

Cellucor's entry into the 300mg caffeine preworkout club yield Extreme mental drive and explosive energy out of the gate. I got to try samples of each flavor courtesy of the Cellucor forum reps. I would classify this preworkout as mental overdrive, more so than a high-pump pre, or smooth endurance pre. Once I drank this I could not sit on it too long before I had to -- had to -- had to -- get moving! It hits hard - every serving. My test results were more explosive energy in the front end for my heavy sets. I was able to increase my weight and felt compelled to do so. The burnoff was same amount of time as most other decent preworkouts. They all mix very easily, and are brightly colored. Strawberry Kiwi was easily the best flavor. The others tasted salty to me (not as much witch blue razz, but a little). Could just be personal.

I'm a huge fan of IBR, but I have to say that I enjoyed the Strawberry Kiwi the most out of these 4 samples. I usually use these products with my 32oz water bottle, but with these samples, I halved the amount of water to get the most out of the flavors. I used them all in the morning as my pre-workout and all around the same time of my usual gym session at 0500. Felt they gave me an added boost of energy during my workout and throughout the day. I usually have about 2 to 3 cups of coffee before I hit the gym, so there was no noticeable jitteriness or tingling from the product. I'll try a tub of the Strawberry Kiwi first and IBR next, but the Cherry Limeade or Lemon drop were not at the top of my list in this product.
