If the caffeinated Skull Crusher is the high-stim lane, this is the same brand intensity without the buzz. Retail positioning calls it a stimulant-free pre-workout for lifters who want pump density at night without fighting the pillow later. No caffeine on the label. No stim stack to manage. Just the pump-and-burn matrix Skull Labs put on the tub.
Every ~2-scoop serve (17.5 g) loads a serious core: 6000 mg citrulline malate (4000 mg citrulline), 3200 mg beta-alanine, and 1500 mg L-arginine alpha-ketoglutarate (A-AKG) — 1050 mg L-arginine. Same scoop stacks 1000 mg each of betaine, taurine and glyceryl monostearate — the volume layer under the citrulline hit.
Focus stays clean with 550 mg choline bitartrate (226 mg choline), 500 mg L-tyrosine and 100 mg glucuronolactone. Niacin (64 mg NE, 400% NRV) and vitamin B6 (18 mg, 1286% NRV) contribute to the reduction of tiredness and fatigue and to normal energy-yielding metabolism. About 20 servings in the 350 g tub when you run the full 17.5 g label serve.
Mix ~2 scoops with 300–350 ml of water, drink 30–45 minutes before training — then crush the session on pump alone.
Stim-free. Pump-heavy. Sleep stays on the table.
Ideal For
- Evening or late workouts where caffeine is off the table
- Training sessions focused on pumps and high-intensity sets without stims
- Adults who want Skull Crusher pump density without the caffeinated version
