Usage Instructions

C4 Extreme is only intended for use on training days and should never be used for more than 8 consecutive weeks. Initially one (5.7g) scoop should be mixed with 4 to 6 oz. of water and consumed 20 to 30 minutes before training. Once personal tolerance to the product has been established the dose can be increased to two scoops if so wished and Cellucor suggests drinking plenty of water.

How it all Stacks up

The blend appears to get much of its power from Creatine Nitrate—an ingredient that is known to fuel intense workouts and aid with the recovery process that follows. The indisputable power of creatine is supported by NO3 so users should expect to feel some powerful pumps. One of the blend’s strengths is the way the nutrients reach the muscle tissues via the blood pathways to deliver the energy required for strong lifts and longer-lasting reps. Beta Alanine and Arginine are a powerful combination that should fuel some good bodybuilding results.

  • Beta Alanine:  increases energy levels and endurance
  • Arginine AKG: Encourages the production of insulin and pumps more blood around the body to deliver the necessary nutrients the muscles need for energy, growth, and repair.

The powerful stimulatory effects of caffeine should provide the extra focus and energy required to push forward and train harder and the addition of bitter orange adds a further edge to energy levels.  This appears to be a potent mix of ingredients, but not all inclusion rates are available, so customer feedback may provide a more complete picture of the blend’s true merits.

potential users need to be aware the manufacturers admit C4 Extreme may contain ingredients that, though legal, may still be prohibited by some sports organizations

Health Considerations

Cellucor warn the product should not be used by anyone who is taking nitrates as a treatment for chest pain or who is taking medication to treat erectile dysfunction. They further state C4 Extreme is only intended for use by people who are over the age of 18 and in good health, so anyone who has health issues or concerns, or who is taking medication should seek medical advice before commencing supplementation. Cellucor C4 Extreme is unlikely to be suitable for use by pregnant or nursing mothers and should never be combined with alcohol.

Customer Feedback

Independent feedback is available and although a few customers speak in disparaging terms—one user even goes so far as to label it a “Crap Product”—but the majority of customers report positive results and more typical responses to the product read:

“Any reviewer that says this product had no effect on them must be on fu##ing crack!! This stuff had me energised and ready to train within 20 mins…and when i say energised i mean i went through a 2 hour workout and literally only noticed that it was 2 hours because the gym was getting ready to close! It gave me loads of energy and even at the end i still had some left in the tank! Seriously good product which gave me no crash also :)”
“This product is great! I take 1 scoop mixed with 4oz of water 15-20 minutes before my workout. As soon as I enter the gym I can feel the cellucor start working. The product basically gives me more energy and endurance on all levels. This is a must have for people who find that they need an extra at the gym.
