Is C4 Original Pre Workout worth buying?

“Cellucor's C4 Original delivers clean energy and proper mental focus during training, with 150mg of caffeine that genuinely doesn't leave you crashed or jittery like some pre-workouts can. Scoring 67/100, it's reliable with genuinely good-tasting flavours, but you're getting proven consistency rather than anything groundbreaking.”

— AIScored Editorial Team, Mar 2026
