C4 AlphaBomb Review
- Full 8g beta-alanine dose
- Citrulline and arginine both individually disclosed at real doses
- Strong across energy and performance
- Very high stimulant content
- Betaine on the lighter side
- 8g beta-alanine causes strong tingles
Effects Timeline
AI-estimated changes in effects over the first 3 hours after taking the recommended serving.
Alpha Bomb is genuinely strong — energy and performance are both excellent, with focus and pumps solid too.
A full 8g dose of beta-alanine and a real 4g citrulline plus 4g arginine combination both stand out.
Cellucor markets this as the highest-stimulant pre-workout in C4's history, and the caffeine dose alone backs that up.
One ingredient, Rauwolfia vomitoria extract, doesn't have enough information on the label to know what it's actually contributing.
Worth knowing: Cellucor also sells a 30-serving "Uncle Samberry" flavor of this same product with meaningfully lighter per-serving doses than the standard 20-serving version reviewed here.
Best for: People who want a genuinely strong, well-rounded formula and don't mind a high stimulant and beta-alanine dose.
