Product Review: Cellucor C4 Pre-Workout

Cellucor’s C4 Pre-Workout is known as one of the original pre-workout supplements and has undergone several changes to its formula since its creation in 2011. It is used to provide long-lasting energy, mental alertness, strength, and endurance, helping to reduce fatigue during workouts.

The C4 is primarily used to increase energy and endurance. It functions as a stimulant, containing a healthy dose of caffeine and creatine which both give the body an energy boost.

As with any supplement that is a blend, the end result is only as powerful as its ingredients. Let’s take a closer look at what comprises Cellucor C4 Pre-Workout and how each ingredient affects your body.

Beta Alanine

The most active ingredient in C4, Beta Alanine is a popular supplement used to enhance muscle endurance. When beta alanine is ingested, it becomes the molecule known as carnosine, which functions as an acid buffer in the body. By blocking lactic acid production, users have reported being able to complete more reps during workouts and experience less fatigue than they normally would. To a lesser extent, beta alanine also helps promote fat loss and lean muscle growth.

Creatine Nitrate

Creatine Nitrate is the second most active ingredient in C4. It is a creatine-nitrate hybrid which is reported to have strong performance enhancing effects during workouts. Much like beta alanine, creatine nitrate helps boost energy while reducing fatigue during workouts, and also helps with muscle gain. Creatine specifically helps with burst muscle contractions; the explosive energy required for intense weightlifting exercises. It does this by fuelling ATP which are high energy molecules used by the muscles during workouts.


L-Arginine is an amino acid that is converted into nitric oxide in the body, it helps promote several metabolic and brain functions. It primarily is used in pre-workouts because nitric oxide causes blood vessels to open wider providing stronger blood flow. It also may help stimulate growth hormone release and insulin in the body.

Vitamin C

Vitamin C is one of the key nutrients to keep the bones healthy. It is essential in helping your bones heal after injuries. Taking vitamin C can help make the bones stronger and more resilient overall.


The most commonly used stimulant available, most of us are all-too-familiar with the effects of caffeine. It provides long-lasting energy and mental alertness which can help enhance workouts greatly. However, it can also negatively impact sleep and anxiety when overused.

Other Key Ingredients

C4 also contains N-Acetyl Tyrosine, a stimulant, along with niacinamide, promoting stronger circulation and increased focus. The final ingredients are vitamin B6 and folic acid, both responsible for the metabolism of amino acids, and vitamin B12 which helps maintain the body’s nerve and blood cells.

Benefits and Drawbacks

Overall, the Cellucor C4 Pre-Workout is excellent at providing long-lasting, explosive energy and is a well-rounded source of nutrients. Not only that, but it also tastes delicious!

It is stimulant based and performance-boosting, best taken 30-60 minutes before a workout, preferably earlier in the day. Some of the drawbacks of this product, potential restlessness and an increased heart rate, can be mitigated if you take tit in the morning. If you are taking a larger amount of the C4, you may experience a common but harmless tingling effect known as paresthesia, which is the result of the increased beta alanine.


The Cellucor C4 is a very popular pre-workout tool that is successful for many people at promoting energy, focus, and overall performance. We’d highly recommend giving it a shot and seeing what benefits it can have for you and your workout. SupZilla loved it so much it is now available to purchase through our online store!!!
