A good pre-workout supplement can make all the difference to your workout and results. Cellucor C4 Extreme is designed to enhance workouts by promoting vascularity, endurance, and bigger pumps. It also has ingredients that maximize muscle growth so your efforts will pay off.

What is in Cellucor C4 Extreme?

Beta Alanine – Bodybuilders everywhere love this ingredient. That’s because it enhances muscle endurance and prevents fatigue better than almost any other ingredient.
Creatine Nitrate – This ingredient takes creatine to the next level. It is a patented form of a creatine molecule and nitric acid. So besides increasing ATP levels, like creatine normally does, Creatine Nitrate also increases nitric oxide levels. As a result, it promotes vascularity, blood circulation, muscle strength, and pumps.
Arginine AKG – Once it enters your blood stream, Arginine AKG is converted into nitric oxide. It increases vascularity and growth hormone levels; which leads to better blood flow, nutrient delivery, and muscle pumps.
Explosive Energy Blend – Ingredients like Vitamin C, Caffeine Anhydrous, and Synephrine HCI are used in Cellucor C4 Extreme to optimize energy levels.

Does Cellucor C4 Extreme Work?

Cellucor C4 Extreme definitely has some premium ingredients. Creatine and Arginine are commonly used in pre-workout supplements, but Cellucor C4 Extreme uses forms of these ingredients that are more advanced. Each serving of this product is packed with large, effective doses of the ingredients.

Many of the ingredients in Cellucor C4 Extreme have been clinically proven or patented, which is always a good sign. It increases the likelihood of effectiveness and safety. The fact that Cellucor C4 Extreme uses all-natural ingredients also increases the safety of this product.

However, there is still a chance that you could experience side effects while using Cellucor C4 Extreme because it uses such large doses of the ingredients. Creatine Nitrate could cause side effects like bloating and water retention.

It's extreme all right...

Tastes great, no burnout, and by far the most amazing pre-workout supplement I’ve ever tried. I broke all my records in the first week of trying it and it made being in the gym seem fun – drastically reduced burn sensation and boosted my focus a ton – got a killer pump – spent a lot of time in the gym without feeling exaustion – consequently it was easy to overdo it and I need to watch it so I don’t injure something. ;p

I have been taking this for only a week but the energy it provides is awesome. The only thing lacking is the pump it provides. Mixes well and the pink lemonade tastes really good.

I’ve been using the C4 Extreme for several months and I’m hooked. Extreme mental focus, beta alanine rushes and energy to spare through the most grueling workout. Maybe not the best pump but I’m sold and highly recommend it to anyone. Probably the best bang for your buck!

I been taking c4 for a week now and the effects have been awesome. I mostly do cardio because i havent had the best experience with weights but immediately after taking this pre-workout i noticed a difference in my focus and the energy is amazing. I cant wait to step it up to 2 scoops.

This is a good solid product for a good price. The servings are great because you get a full 30 day supply. I have tried a lot of pre-workouts and it is hard to find one that holds up past 1-1.5 weeks. I have been taking C4 for almost 3 weeks and the effects are holding strong. The only reason I did not give this product a 5 is the intensity is not as strong as Jack3d, but for the price and servings I can deal with it. Don’t get me wrong it is still pretty intense and the pump is great!!
