C4 Energy RTD

Pre-workout in a can for the days you forgot the tub. Or the days you just need to wake up.

What It Is

C4 Energy is Cellucor's carbonated energy drink in a 16 oz can. Each can has 200mg of caffeine, zero sugar, and no artificial colors, plus CarnoSyn beta-alanine and vitamin B12. It's NSF Certified for Sport, which means it's third-party tested for banned substances. Flavors we carry: Cereal Killer, Sour Gummy, Hawaiian Punch, Watermelon Jolly Rancher, Hawaiian Pineapple, Pink Lemonade, Classic Lemonade, and Strawberry Blast.

Who It's For

People who train right after work and don't want to mix anything in the parking lot. Students and shift workers who need caffeine without a sugar crash. Tested athletes who need the NSF logo on the can. This is not for you if you're sensitive to caffeine or already had two coffees. 200mg is a real dose. And if you want full clinical doses of citrulline and beta-alanine, a scoop of pre-workout still beats a can.

How It Helps

• 200mg of caffeine per can supports energy, alertness, and focus.
• CarnoSyn beta-alanine helps buffer the burn so you can push a few more reps.
• Zero sugar, so no crash an hour later.
• Vitamin B12 supports normal energy metabolism.
• Carbonated and cold, which honestly does half the work of waking you up.

What's Inside
