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 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.

Very nice taste, sweet, looks beautiful, but the effect is not to strong.. maybe a bit soft. It's my first time that I use pre workouts, however, I put 1 scoop and haven't feel any difference between that and a cup of strong coffee.*

He is a good commodity. But 50 Servings are prone to moisture. It is recommended to buy 30 Servings. Used before training, there is a very powerful help. If you need help. Buying him is a good choice. Just the taste I'm not used to.*
