Sledgehammer is a powerful pre-workout built for serious athletes and lifters. Featuring dual-source caffeine, Beta-Alanine, L-Arginine, Agmatine Sulfate, and Alpha GPC, this bold formula delivers sustained energy, amplified strength, and mental sharpness—no crash, all intensity.
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. |

It's a full-intensity, fully-dosed pre-workout with 300 mg of caffeine anhydrous and 100 mg Infinergy™ DiCaffeine Malate, plus beta-alanine and pump ingredients — built for serious training, not a mild everyday buzz. See our pre-workout ingredient guide.
300 mg of caffeine anhydrous per scoop, plus 100 mg Infinergy™ DiCaffeine Malate, a slower-release caffeine 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.
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.
Mix one scoop with water 30–45 minutes before training, earlier in the day. Avoid late-evening use because of the caffeine.
Many people do, but with 300 mg caffeine anhydrous plus Infinergy per scoop 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.
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.
