Nutrabolt, owner of C4 Energy, announced its 2026 summer flavor lineup led by the nationwide launch of C4 Performance Energy Pink Lemonade, a new limited-time offering. Joining the lineup are two exclusive retailer launches: Hawaiian Punch Berry Blue Typhoon, available only at Circle K, and Cherry Cola, available only at Casey’s.

Pink Lemonade headlines the summer collection as the brand’s marquee seasonal launch and supported nationally as the brand’s “Official Energy Drink of Summer.” Inspired by one of summer’s most iconic beverages, the flavor blends sweet raspberry notes with zesty lemonade for a bright, refreshing taste profile, the company says. 

“Last summer’s Classic Lemonade was C4’s first limited-time flavor release and it resonated strongly with our consumers, proving there is high demand for seasonal flavor innovation from our brand,” said Emily Hoyle, senior vice president of marketing at Nutrabolt, in a statement. “Pink Lemonade builds on that success with a fresh take on a summer classic, designed to drive trial and cultural relevancy throughout the season. At the same time, Hawaiian Punch Berry Blue Typhoon and Cherry Cola reflect our continued focus on pairing bold flavors with retail-exclusive launches that create excitement where consumers shop.”

In addition to Pink Lemonade, Nutrabolt is expanding its summer lineup with two exclusive retailer launches:

Cherry Cola Performance Energy: Available exclusively at Casey’s, this nostalgic take on a classic soda flavor pairs cola taste with cherry notes and C4’s signature energy formula. Rewards shoppers can grab it at participating Casey’s locations in May and June for just $1.50.

Hawaiian Punch Berry Blue Typhoon Performance Energy: Available exclusively at Circle K, this tropical-inspired flavor delivers a taste consumers already know and love alongside a national sweepstakes giving fans the chance to win a trip to Hawaii. The sweepstakes runs through June 30, at 11:59:59 pm ET. 

Each 16-ounce can of C4 Performance Energy delivers 200 mg of caffeine and zero sugar.

The launches are part of C4 Energy’s broader summer platform, which includes sampling, influencer activations, digital campaigns, and in-market events throughout the season.

Pink Lemonade will be available for a limited time at retailers nationwide and online at C4Energy.com while supplies last.
