Full-Dose Formula Breakdown
Every active, every milligram — exactly as it reads on the label. No proprietary blends. No amino spiking.
| Ingredient | Per Scoop | Why it's in there |
|---|---|---|
| Beta-Alanine | 1,600 mg | Buffers acid build-up so you can grind out extra reps before fatigue sets in. (Yes — this is the tingle.) |
| L-Arginine | 1,000 mg | A nitric-oxide precursor for blood flow and a fuller pump. |
| Agmatine Sulfate | 500 mg | Works with arginine to extend the pump and nutrient delivery. |
| Caffeine Anhydrous | 300 mg | Fast-hitting, clean energy and focus. |
| Infinergy™ DiCaffeine Malate | 100 mg | A slower-release caffeine so energy tapers off instead of crashing. |
| Alpha-GPC (50%) | 250 mg | Sharpens focus and mind-muscle connection. |
| Green Tea Extract (50% EGCG) | 200 mg | Antioxidant support that pairs with the caffeine. |
| Piperine (Piper nigrum) | 5 mg | Black-pepper extract that helps your body absorb the actives. |

Frequently Asked Questions
How strong is Sledgehammer?
It's a full-intensity, fully-dosed pre-workout with ~375 mg of caffeine from two sources (300 mg Caffeine Anhydrous + Infinergy™) plus beta-alanine and pump ingredients — built for serious training, not a mild everyday buzz. See our pre-workout ingredient guide.
How much caffeine is in Sledgehammer?
About 375 mg per serving, from two sources — 300 mg Caffeine Anhydrous plus 100 mg Infinergy™ DiCaffeine Malate for smoother, longer energy. That's a strong dose, so start with a half scoop to assess tolerance, and don't take it within about 5–6 hours of bed.
Why does Sledgehammer make me tingle or itchy?
That's beta-alanine — a harmless, well-studied endurance ingredient. The tingle (paresthesia) fades as your body adapts. Full explanation in why pre-workout makes you itchy.
When should I take Sledgehammer?
Mix one scoop with water 30–45 minutes before training, earlier in the day. Avoid late-evening use because of the caffeine.
Can I take Sledgehammer every day?
Many people do, but with ~375 mg caffeine it's smart to watch your total daily intake and take periodic breaks so your tolerance doesn't creep up. If you're sensitive to stimulants, check with your provider.
Does Sledgehammer have creatine?
No — it's a stim and pump formula, so it stacks cleanly with our Pure Power creatine or the creatine already in Category5.
Mix one scoop with 6–8 oz of water or your favorite drink, 30 to 45 minutes before training. On non-training days take one scoop as needed to maintain energy, strength, and focus. Do not exceed 1 scoop in 24 hours. Contains no creatine — stack with Pure Power or Category5 if you want it.
