Cellucor C4 Original
by Cellucor
C4 Original is one of the world's most iconic pre-workouts, featuring 150mg caffeine, patented CarnoSyn beta-alanine, and a proprietary Explosive Energy Blend. First launched in 2011, it has sold over 2 billion servings globally. The formula is designed for reliable, moderate energy and the signature beta-alanine tingle that many gym-goers associate with an effective pre-workout.
AI Review Summary
Cellucor C4 Original is a classic pre-workout that prioritises reliability and broad appeal over maximum performance. The 150mg caffeine and CarnoSyn beta-alanine provide a familiar pre-workout experience. However, ingredient doses are generally below clinical thresholds, and the use of proprietary blends limits transparency. At 23-28 GBP for 30 servings, it is slightly overpriced compared to UK alternatives with better-dosed formulas.
