Full Review
C4 Original has earned its spot as the best-selling pre-workout in America for good reason. It's the perfect entry point for anyone new to pre-workout supplements.
Energy & Focus: The 150mg caffeine dose hits a sweet spot — enough to feel energized without the jitters or crash that higher-stim products can cause. You'll notice a clean energy boost within 15-20 minutes of taking it.
Performance: Beta-alanine at 1.6g provides the signature tingling sensation and helps push through those last few reps. While the creatine nitrate dose is modest at 1g, it does contribute to a slight performance boost.
Taste & Mixability: Cellucor has mastered their flavoring. Cherry Limeade and Icy Blue Razz are standouts. It mixes cleanly with minimal clumping.
Value: At roughly $1 per serving, C4 Original offers excellent value, especially for beginners who don't need clinical doses of every ingredient.
The Bottom Line: If you're new to pre-workouts, C4 Original is the safest bet. It's affordable, effective for beginners, and the mild stimulant profile lets you build tolerance gradually. More advanced users will want to look elsewhere for fully dosed formulas.

Been using C4 Original for about 3 months as my very first pre-workout. The 150mg caffeine is exactly right — I feel energized without the jitters or heart-racing feeling I was worried about. Cherry Limeade flavor is genuinely delicious and it mixes clean with no clumps. Great value at a dollar a serving.

C4 gets the job done for someone just starting out. The energy kicks in fast and the price point is unbeatable. After 6 months of consistent training though I needed to move up to something with higher doses. Still the best first pre-workout I can think of recommending — just know you'll outgrow it.
