The Formula

What's Inside

Every gram, every reason. Nothing you can't explain.

One scoop of PUMP Stim. Fully dosed, naturally flavored, no proprietary blends. Here's what each ingredient is doing — and why it earned its spot.

The Pump Engine

10GRAMS

L-Citrulline

The pump foundation. Raises nitric oxide to open blood vessels and push more blood into working muscle. Dosed at the full clinical 10 g — where it actually works.

2.5GRAMS

Arginine Nitrate (as NO3-T®)

Two nitric-oxide pathways in one ingredient — arginine and nitrate — for a pump that builds fast and holds through the session.

3GRAMS

Glycerol (as GlycerSize®)

Pulls water into the muscle for that full, dense, skin-stretching look — and helps you stay hydrated under load.

100MG

Epicatechin (from cocoa extract)

A cocoa flavanol that supports nitric-oxide output and blood flow. The "why is this even in here" ingredient most brands skip to save a dollar.

400MG

L-Norvaline

Helps sustain arginine levels so the pump carries deeper into your last sets instead of fading early.

Strength & Endurance

3.5GRAMS

Beta-Alanine

Buffers the acid burn so you get more quality reps before fatigue sets in. Yes — it's the ingredient behind the tingle.

3GRAMS

Betaine Anhydrous

Supports power output and cell volume — strength and fullness working together.

1.5GRAMS

Taurine

Supports hydration, endurance, and focus, and smooths out the edge from the stimulants.

Clean Energy & Focus

175MG

Total Caffeine (anhydrous + Infinergy® dicaffeine malate)

A fast hit paired with a longer, smoother release — real energy without the jitters or the crash. 175 mg total, printed honestly, not buried in a blend.

BACTIVE FORMS

B6 · B12 · Niacin

The active, bioavailable forms — P-5-P (B6, 5 mg), methylcobalamin (B12, 4 mcg) and niacin (16 mg) — to support energy metabolism. The good versions, not the cheap ones.

Hydration & Pump Support

780MG SODIUM

Baja Gold® Sea Salt

Real electrolytes to keep you primed and pumped — not flat, depleted, and cramping halfway through.

1GRAM

Vitamin C (ascorbic acid)

Antioxidant support that helps protect nitric oxide, so the pump you built doesn't fade before you're done.
