Which pre-workout is yours?

We make 6 pre-workouts because they do different jobs. One question sorts it: how much caffeine do you want?

None. Zero.

Night training, second sessions, or you're already three coffees deep.

Berserker Serum ($59.99). Pure pumps and endurance. Stacks clean with whatever caffeine you already run.

Flood V2 ($54.99). The full pre-workout job minus caffeine: pumps, focus, electrolytes. Pick this one if you want more than pumps.

Some. Enough to drive, no fireworks.

Berserker Focus ($39.99). Built focus-first: L-tyrosine and Alpha GPC with enough caffeine behind them. The right first Hollow pre-workout, and it holds up for studying and long workdays too.

A lot. 425mg, experienced users.

Shadow ($44.99). Two caffeine sources: 350mg hits fast, 75mg Infinergy releases on a delay. Same peak, longer curve, no cliff. Full breakdown on the label.

Maximum. You know exactly what you're doing.

Two roads:

Berserker Stim ($59.99). ~475mg caffeine plus 10g of citrulline and arginine. Max output and max pumps in one tub. The serving is 40 grams because full doses take up space.

Shadow Realm ($54.99). Our strongest energy and focus. If you have to ask whether you're ready, you're not. Start with Shadow and come back.

Stacking rules

Serum or Flood V2 stack with any of the stim formulas. Never run two stim pre-workouts together. Ever.

Sweat more than you stim? PD Special ($54.99) is hydration plus creatine, built with Pat Damiano. Different job, same standard.
