Cellucor C4 Performance Energy Carbonated RTD in Orange Slice is a ready-to-drink option designed for active days and training sessions. The case includes 12 bottles, each 500 ml, for convenient use around workouts. Every 500 ml serving lists 0 g protein, 0 g carbohydrates, 0 g fat, and 0 g salt. The drink relies on caffeine for a focused energy lift and delivers a lightly carbonated, citrus-flavored profile that’s easy to sip during training. Key ingredients work together to support energy and focus. L-Arginine is present at a small level to support nitric oxide production and blood flow, while Taurine contributes to hydration-like support and endurance during training. Betaine can help support power output and training adaptations, with B vitamins (Niacinamide and Cyanocobalamin) contributing to energy metabolism. The formula is sweetened with sucralose and steviol glycosides and balanced with malic and citric acids to enhance the citrus taste. How to use it for best results: use this as a pre-workout or during-workout boost. Drink about 15–30 minutes before you start training, or sip a bottle through a longer session if needed. Keep caffeine in mind alongside other sources and avoid consuming late in the day. For the best flavor, chill the drink and enjoy the crisp orange finish. Notes on formulation: nutritional facts and ingredients may vary slightly between flavours. In this Orange Slice variant, you get the same energy-supporting profile with a citrus-forward taste. This product is intended to complement a balanced training routine and is not a substitute for a varied diet or medical advice.
