C4 Energy has entered the energy shot category with the launch of C4 Performance Energy Shots, a pocket-sized format featuring 200 mg of caffeine, CarnoSyn beta-alanine, and zero sugar.

The format is well-suited for gym-goers who don’t want a full 16-ounce pre-workout beverage, busy people looking for fast on-the-go energy, and energy shot users who want better flavor and performance, the company reported. Additionally, they’re small enough to take in carry-on bags through TSA checkpoints, the company noted.

The shots will be available in three flavors: Frozen Bombsicle, Hawaiian Punch Fruit Juicy Red, and Popsicle Grape.

C4 Performance Energy Shots are NSF certified for sport.
