C4’s New Classic Lemonade Delivers Summer Flavor With Serious Performance
C4 is no stranger to the top shelf of the performance energy category, and now it's leveling up again with a new limited-edition seasonal release: Classic Lemonade. As temps rise, C4's latest flavor is bringing nostalgic summer vibes to the gym, with the same explosive formula that made it a leader in functional energy.
But don’t let the flavor fool you—this is still one of the most performance-driven drinks on the market.
What Sets C4 Apart
Unlike typical energy drinks that rely solely on caffeine and hype, C4 brings a true pre-workout edge to the can:
Carnosyn® Beta-Alanine: Clinically studied to improve muscular endurance and delay fatigue. It supports increased work capacity and buffering of lactic acid, giving lifters and athletes more in the tank.
BetaPower® Betaine Anhydrous: Enhances strength, power output, and muscular hydration. This ingredient supports better performance under stress and is rarely seen in mainstream energy drinks.
200mg Caffeine: Delivers clean, sustained energy without the crash. Ideal for both training sessions and mid-day boosts.
0g Sugar: Performance-first with no unnecessary fillers.
NSF Certified for Sport: Meaning every batch is tested and trusted by athletes who compete. No banned substances, no guesswork. This is BIG because this certification is not cheap meaning that C4 is committed to quality.
This isn’t just another can on the shelf. It’s a precision-formulated, sports-tested tool for peak performance. That said, my only knock on the formula is that C4 doesn’t disclose the specific dosing for the Beta-Alanine or Betaine Anhydrous on the can itself—so we don’t even know if it’s truly hitting clinical doses or just being pixie-dusted in.
Why Classic Lemonade?
Lemonade is a staple flavor for summer—but C4 doesn’t do anything halfway. Expect a bold, sweet-tart profile that’s crisp, refreshing, and hits hard after a tough training session. Perfect straight from the fridge, or slammed before a hot workout in the sun.
If you’re someone who trains hard and doesn’t want to compromise flavor for function (or vice versa), this drop was made for you.
Final Take
C4’s Classic Lemonade is more than just a flavor drop—it’s a reminder that you don’t need to choose between science-backed performance and seasonal energy. With clinically dosed ingredients like Carnosyn and BetaPower, and NSF certification to back it, this limited-edition can is built for athletes who train with intention.
Grab it while it lasts. Keep an eye out from our 1-sip review once we can get our hands on this.
