Efectiv Nutrition Project PUMP 480g, 10g Citrulline and 3g HydroPrime Per Stim-Free Scoop

Project PUMP is a stimulant-free pre-workout built around pump, blood flow and training quality rather than caffeine. Each 24g full scoop (12g half scoop for build-up) delivers 10g citrulline malate (2:1 ratio), 3g HydroPrime glycerol powder at 65 percent and 3g L-tyrosine for focus. The 480g tub gives 40 full servings at around 5.5 calories each.

The formula also includes taurine, Himalayan pink salt, VitaCholine, FitNox (moringa, pomegranate, kaempferia parviflora) and CognatiQ coffee fruit extract. Zero caffeine and zero stimulants of any kind, so it suits evening sessions and people who manage their stimulant intake separately.

Mix one scoop with 300 to 400ml of chilled water 20 to 30 minutes before training. Start with half a scoop to assess tolerance for the glycerol component. Some users combine half a scoop of Project PUMP with half a scoop of a stimulant pre-workout for a customised stack.

Project PUMP suits evening lifters, caffeine-sensitive users and anyone who wants pump ingredients independent of their stimulant dose. Note: HydroPrime is hygroscopic and naturally absorbs moisture, so minor clumping in the tub is normal and does not affect quality. For a full caffeinated pre-workout with pump support built in, XL Nutrition The Purgeprovides 8g L-citrulline alongside 400mg caffeine.

Frequently Asked Questions

How do I take Project PUMP pre-workout?

Mix one 12g scoop with 300 to 400ml of chilled water and drink 20 to 30 minutes before training. Start with half a scoop on the first use to assess tolerance for the glycerol component. Project PUMP contains zero caffeine, so timing is flexible for evening sessions.

How is Project PUMP different from Efectiv Legacy?

Project PUMP is stimulant-free, built around pump and blood flow with 10g citrulline malate and 3g HydroPrime per scoop. Efectiv Legacy is a full caffeinated pre-workout with 400mg caffeine plus 8g L-citrulline. Project PUMP suits evening training or caffeine-sensitive users; Legacy suits stronger energy and focus from a single scoop.

Why does Project PUMP clump in the tub?

HydroPrime is hygroscopic, meaning it naturally absorbs moisture from the air. Minor clumping is normal and does not affect quality, taste or effectiveness. Break up clumps with a spoon before scooping, and store the tub with the lid tightly closed in a cool, dry place.
