No Hype. Only Performance.

Every pre-workout promises a pump. Most deliver a heart rate.

4D Pump is stimulant-free by design. No caffeine, no yohimbine, nothing to raise your pulse or shorten your evening. What it does instead is push blood, water, and focus into working muscle — at doses that match the research rather than gesture at it.

WHAT IT DOES

The pump. 6,000mg of 3D Pump Breakthrough™ — vegan-fermented citrulline, glycerol, and amla extract — is the full studied dose, not a fraction of one. Citrulline supports nitric oxide production to open vessels; glycerol pulls water into muscle tissue. 1,500mg of Nitrosigine® and 508mg of VasoDrive-AP® work the same pathway through different mechanisms. Three angles on one outcome.

The hydration. 600mg potassium, 310mg sodium from pink Himalayan salt, and 200mg of magnesium bisglycinate — a real electrolyte load, not a token pinch. Pumps are a fluid phenomenon. Dehydrated muscle doesn't fill.

The focus. 2,000mg of L-tyrosine plus 25mg of Sebrium DCD™ delivers clarity and drive without stimulants. You get locked in, not wired.

WHO IT'S FOR

Anyone training in the evening who still wants to sleep. Anyone stacking it on top of a stim pre-workout. Anyone who's realized the jitters were never the point — and anyone chasing the kind of pump that makes you look at your own arm between sets.

HOW TO USE IT

One scoop (18.9g) in 12–16 oz of cold water, 20–30 minutes before training. Stimulant-free, so it works any time of day. Stack with Bone Crusher when you want stimulants — see the note below.
