Efectiv Project PUMP, 10g Citrulline and 3g HydroPrime in a Stimulant-Free Pre-Workout

Efectiv Nutrition Project PUMP is a stimulant-free pre-workout built entirely around pump, blood flow and training quality rather than caffeine-driven energy. It is designed for evening sessions, caffeine-sensitive users and anyone who wants to control their stimulant intake separately from their pump and focus ingredients. At 40 servings per tub, it is also the highest-serving pre-workout in the Efectiv range.

Each 12g serving provides 10g citrulline malate (2:1 ratio, yielding roughly 6.7g pure citrulline for nitric oxide production and blood flow), 3g HydroPrime (glycerol powder at 65% for intracellular hydration and muscle volumisation), 3g L-tyrosine (for sustained focus), taurine, Himalayan pink salt (for sodium and fluid balance), VitaCholine (choline bitartrate for cognitive support), FitNox (moringa oleifera, pomegranate and kaempferia parviflora for additional nitric oxide support through a different pathway) and CognatiQ (coffee fruit extract for mental clarity without caffeine-like stimulation). The 480g tub delivers 40 full servings at just 5.5 calories each.

Mix one scoop with 300 to 400ml of water 20 to 30 minutes before training. The pump effect builds progressively through the session as citrulline converts to nitric oxide and glycerol drives water into muscle cells for visible volumisation. Some users combine half a scoop of Project PUMP with half a scoop of Legacy for a balanced pump-plus-energy pre-workout on harder training days, giving them full control over the stimulant dose.

Project PUMP suits evening lifters, people who are caffeine-sensitive, and anyone who wants to separate pump ingredients from stimulants for full stack control over their pre-workout experience. Note that the HydroPrime glycerol is hygroscopic (it naturally attracts moisture from air), so minor clumping in the tub is normal and does not affect quality, taste or effectiveness. If you want a full stimulant pre-workout with built-in pump and citrulline support, Efectiv Legacy provides 8g pure L-citrulline alongside 400mg caffeine from dual sources.

Frequently Asked Questions

Can I take Project PUMP at night without affecting sleep?

Yes. Project PUMP contains zero caffeine and zero stimulants of any kind, so it will not interfere with sleep regardless of when you train. It is specifically designed for evening sessions where a caffeinated pre-workout would disrupt your rest. The pump, focus and training quality benefits come entirely from citrulline, glycerol, tyrosine and other non-stimulant active ingredients.

Can I stack Project PUMP with Legacy or another caffeinated pre-workout?

Yes, and many users do exactly this. Combining half a scoop of Project PUMP with your regular pre-workout gives you both the pump ingredients (citrulline, glycerol, FitNox) and the energy and focus from the stimulant product. Since Project PUMP has no caffeine, you control the total stimulant dose entirely through your other pre-workout.

Why does Project PUMP powder clump in the tub?

The HydroPrime glycerol in Project PUMP is hygroscopic, meaning it naturally absorbs moisture from the air. This can cause minor clumping over time but does not affect the quality, taste or effectiveness of the product. Simply break up any clumps with a spoon before scooping. Store the tub with the lid tightly closed in a cool, dry place to minimise moisture exposure.
