Cellucor C4 Carbonated RTD - Purple Frost

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.

How Cellucor Pre-Workout works

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.

Why choose Cellucor C4 Carbonated RTD

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.

• Vitamin B3 (30 mg, 200% RDI) and Vitamin B12 (6 mcg, 250% RDI) are included alongside the performance ingredients
• 50 mg of N-Acetyl-L-Tyrosine is added, an amino acid included for mental focus during training
• 0 g of protein, fat and carbohydrate, plus 0 mg sodium, keep the panel simple to read at a glance

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.

Getting the most from it

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.
