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.

6.2/10
GOOD

Caffeine at 200mg is clinical dose and the real driver here. But L-Citrulline at 1.2g is only 20% of optimal (6g), and L-Arginine at 1.2g is 20% of optimal. Beta-Alanine at 2g is 63% of optimal. For a pre-workout, the pump and endurance ingredients are significantly underdosed. The energy/focus complex works, but the performance side falls short.
