- Full 5g creatine dose
- Dual citrulline sources for pumps
- NSF certified for athletes
- Alanyl-glutamine included for recovery support
- Not actually stimulant-free — contains paraxanthine
- Only 20 servings per tub
- Energy is the comparative weak point
- Formula completely different from the original Alpha Bomb
Effects Timeline
AI-estimated changes in effects over the first 3 hours after taking the recommended serving.
Alpha Bomb Sport is a genuinely different formula from the standard Alpha Bomb — no caffeine specifically, but this is not a stimulant-free product.
It contains a full 200mg dose of paraxanthine, a close relative of caffeine that works the same way in your body.
Pumps and performance both land near the top of the scale, helped by a full 5g creatine dose and a real double dose of citrulline (both the plain and malate forms together).
It's also NSF Certified for Sport, meaning it's independently tested for banned substances and contaminants — a real plus for competitive or drug-tested athletes.
Two newer ingredients round out the mood and performance side — a concentrated form of Rhodiola's active compound, and a whey-derived peptide — both with real published research behind them, though both were studied over weeks of daily use rather than a single dose.
The formula also includes Alanyl-L-Glutamine for hydration and recovery, a genuinely useful addition even though it's not something that shows up as energy, focus, pumps, or performance.
Best for: People who want strong pumps and performance without literal caffeine, but who are comfortable with a real, similarly-acting alternative stimulant.
