C4 Carbonated is the ready-to-drink version of one of the world's best-selling pre-workouts, packed into a fizzy, zero-sugar 473ml can.

Cellucor C4 Carbonated RTD - Cotton Candy is a ready-to-drink pre-workout from Cellucor, built for lifters who want a real pre-workout dose without measuring a scoop. Each 473 mL can delivers 150 mg of caffeine anhydrous alongside 2000 mg of CarnoSyn beta-alanine, so you get a genuine training stimulant profile straight from the fridge. It suits gym-goers who want convenience on a busy morning or a quick can before an afternoon session.
Caffeine anhydrous is a central nervous system stimulant that blocks adenosine receptors, which is what produces the alert, ready-to-train feeling shortly after you drink it. In Cellucor C4 Carbonated RTD, that 150 mg dose sits alongside 1650 mg of L-citrulline, an amino acid your body converts toward nitric oxide production, supporting blood flow to working muscle during a set.
Beta-alanine works on a different timeline. Regular use raises the carnosine content of skeletal muscle, which helps buffer the acid build-up that contributes to fatigue during high-rep training. Betaine anhydrous (BetaPower) is included at 1250 mg for its role in cellular hydration, rounding out a formula built from ingredients with real research behind them rather than a proprietary blend that hides individual doses.
Choosing a carbonated format over a powder comes down to convenience. Cellucor C4 Carbonated RTD Cotton Candy arrives pre-mixed and pre-dosed, so there is no scoop to level and no shaker to wash. The nutrition panel is fully disclosed, and a few details go beyond the headline actives.
Together, that means a stimulant dose sits alongside ingredients aimed at blood flow and training endurance, all in one 473 mL can rather than separate tubs.
Most people open a can of Cellucor C4 Carbonated RTD around 20 to 30 minutes before training, which gives the 150 mg of caffeine time to take effect before the first set. Because it carries no protein or carbohydrate itself, it pairs naturally with something from our protein range afterwards, or with a creatine routine if you already run one, since creatine is not part of this formula.
If your shelf already holds powdered formulas, treat Cellucor C4 Carbonated RTD as the grab-and-go option on time-poor days, and browse the wider pre-workout range if you want to compare doses and formats side by side.
Drink one chilled can roughly 20 to 30 minutes before training, or sip through your workout. Start with half a can the first time if you are new to beta-alanine. As it contains caffeine, do not exceed one can per day and account for your total daily caffeine intake.
Lifters and gym-goers who want pre-workout performance in a grab-and-go can. It is ideal before training when you do not feel like mixing a powder, and the carbonated, zero-sugar format makes it an easy upgrade over a regular energy drink. The 150mg caffeine keeps it manageable for most people. Best ice cold.
That harmless tingle is from beta-alanine (paraesthesia) and is completely normal. It is not an allergic reaction.
Yes. Unlike most energy drinks it includes performance doses of beta-alanine, citrulline and betaine, so it works as a ready-to-drink pre-workout.
No. It is sugar-free with just 30 calories per 473ml can.
150mg of caffeine anhydrous per 473ml can.
Yes. Cellucor C4 Carbonated RTD Cotton Candy does not contain creatine, so it works well alongside a separate creatine routine rather than replacing one. Add your usual creatine dose on its own schedule and use the can for the caffeine, beta-alanine and citrulline dose around training.
It can be, though 150 mg of caffeine anhydrous is a full stimulant dose for most people. If you are sensitive to caffeine or training very early, start with how you usually respond to a strong coffee before your first full can.
Keep the can upright in a cool, dry spot out of direct sun, the same as any carbonated drink. Refrigerating it before training is optional, but many people prefer it cold. Once opened, drink it in one sitting since it is a single 473 mL serving.
The active doses work the same way, but format differs. This can is pre-mixed and carbonated with 150 mg caffeine, 2000 mg beta-alanine and 1650 mg L-citrulline already dissolved, so there is no mixing and no shaker required.
