C4 Performance Energy Drink is Cellucor's zero-sugar, carbonated pre-workout energy drink built around 200mg of Caffeine Anhydrous alongside a genuine pre-workout ingredient set — CarnoSyn® Beta-Alanine, L-Citrulline, and BetaPower® Betaine Anhydrous — rather than caffeine alone. This combination targets muscular endurance, blood flow and pump, and cellular hydration on top of the caffeine-driven energy and alertness. N-Acetyl-L-Tyrosine rounds out the formula for focus support. Zero sugar, zero calories, using Sucralose and Acesulfame Potassium as sweeteners. Consume one can 20-30 minutes before dominating exercise and/or life. Some individuals may experience a harmless tingling sensation attributed to Beta-Alanine. Available in Cosmic Rainbow (Skittles collaboration), Frozen Bombsicle, Strawberry Watermelon Ice, Orange Slice, Cherry Limeade, Arctic Snow Cone, Midnight Cherry, Grape Frost, Starburst, and Popsicle flavors.†

CarnoSyn® Beta-Alanine — Fighting Fatigue Rep After Rep
CarnoSyn Beta-Alanine is an amino acid that helps buffer lactic acid buildup in muscle tissue, reducing the burning sensation during high-intensity training so you can push through more reps. Benefits of CarnoSyn Beta-Alanine have been shown to correlate with cumulative, consistent daily use rather than a single acute dose — meaning the endurance benefits build over weeks of regular consumption rather than appearing immediately with your first can. The characteristic tingling sensation (paresthesia) some people feel is a well-documented, harmless, and expected response — not a side effect requiring concern.†
BetaPower® Betaine and L-Citrulline — Hydration and Pump
BetaPower Betaine, derived naturally from beets, helps maintain muscle cell hydration and supports muscle power output and endurance — like Beta-Alanine, its benefits are most pronounced with consistent daily use rather than a single serving. L-Citrulline is an amino acid that converts into L-Arginine in the body, boosting nitric oxide production to improve blood flow, vascularity, and the muscle pump sensation — this is the one ingredient in the formula with documented acute (single-dose) effects, meaning you can feel a pump-related benefit from Citrulline even on your very first can.†
N-Acetyl-L-Tyrosine — Focus to Match the Energy
N-Acetyl-L-Tyrosine is a modified, more bioavailable form of the amino acid L-Tyrosine — the direct precursor to dopamine and norepinephrine, the neurotransmitters central to focus, alertness, and drive. Its inclusion here complements caffeine's stimulant effect with a more targeted cognitive support ingredient, aiming to sharpen mental focus alongside the physical energy boost.†
C4 Performance vs. C4 Ultimate — Choosing Your Energy Level
C4 Performance Energy and C4 Ultimate Energy are Cellucor's two main pre-mixed energy drink lines, and while similar, they target different needs. C4 Ultimate has more caffeine (300mg vs. 200mg) and is built around a Tri-Stim blend of Caffeine, TeaCrine, and Dynamine for maximum stimulant intensity. C4 Performance contains more active pre-workout ingredients — Beta-Alanine, Betaine, and L-Citrulline — at a milder, more moderate caffeine dose, making it a more affordable, everyday option for those who want real pump and endurance ingredients without maxing out on stimulants. If you want the strongest possible energy hit, choose Ultimate. If you want a balanced blend of moderate energy plus genuine pre-workout ergogenic support, Performance is the better fit.†
Frequently Asked Questions
Why do I feel tingling after drinking C4 Performance?
This is a harmless, well-documented, and expected response to CarnoSyn Beta-Alanine, known as paresthesia. It is not a sign of an adverse reaction and generally decreases with continued regular use.†Do I need to drink C4 Performance every day for it to work?
For the Beta-Alanine and Betaine components specifically, yes — both ingredients build their endurance and hydration benefits with consistent, cumulative daily use rather than a single serving. L-Citrulline is the exception, providing acute pump benefits even from your first can.†How does C4 Performance compare to C4 Ultimate?
C4 Ultimate has more caffeine (300mg vs. 200mg) and uses a Tri-Stim blend (Caffeine, TeaCrine, Dynamine). C4 Performance has less caffeine but includes more dedicated pre-workout ingredients (Beta-Alanine, Betaine, L-Citrulline) at a lower price point.†Is C4 Performance Energy third-party tested?
No — as a canned beverage, C4 Performance Energy is not NSF Certified for Sport, unlike some of Cellucor's powder-format products (such as C4 Sport or C4 Ripped Sport). Tested athletes should factor this into their decision.†
