C4 Original Pre-Workout

This product is for boosting energy, focus, and endurance during workouts.. The product uses premium, patented forms for many ingredients, including an excellent B vitamin complex and a solid caffeine dose. However, key performance ingredients like L-Citrulline, L-Arginine, and Creatine Nitrate are significantly underdosed, limiting their effectiveness for pump and strength gains. It's a good option for basic energy and endurance, but not for maximal performance.

8.0/10
EXCELLENT
