Gaspari Proven Pump - Mixed Berry, 473g (32 Serves)

Gaspari Proven Pump - Lemon Drop, 473g is a stimulant-free pump formula from Gaspari, built for lifters who want the vasodilation and muscle fullness of a pre-workout without the jitters or the afternoon caffeine comedown. It sits in the Pre-Workout category on nzsupps.co.nz and works well for evening training, when a caffeine hit would keep you wired, or as an add-on for anyone already running a stim-based pre-workout who wants extra pump layered on top. The bottle is priced at $58.95 NZD and every full capful is built around 1.5g of L-citrulline, the largest active in the formula. This listing covers the Lemon Drop side of the range, with a Mixed Berry option available if you prefer a different flavour.

How Gaspari Pre-Workout works

The pump effect in Gaspari Proven Pump starts with L-citrulline. Once absorbed, citrulline is converted to L-arginine in the kidneys, and arginine is the substrate that nitric oxide synthase uses to produce nitric oxide in the lining of your blood vessels. More nitric oxide relaxes the smooth muscle in the vessel wall, widening it, so more blood carrying oxygen and nutrients reaches working muscle during a set. Proven Pump adds a direct 1g of L-arginine on top of the citrulline dose, giving the nitric oxide pathway substrate from two angles instead of one.

Betaine anhydrous works differently. It's an osmolyte, meaning it helps cells manage water balance under stress, and it also functions as a methyl donor in several metabolic pathways tied to power output and endurance. Alongside it, the 12g of vegetable glycerol in every serving is a humectant that draws water into muscle tissue, a process called hyperhydration. Between the citrulline-driven blood flow and the glycerol-driven cell volumisation, the combined effect is the fuller, tighter look and feel lifters chase from a pump product.

Why choose Gaspari Proven Pump

What sets Gaspari Proven Pump apart from a lot of pump products on the market is that every active is dosed as a single, named ingredient rather than folded into a blend where you can't see the split. You get 1.5g of L-citrulline, 1.25g of betaine anhydrous and 1g of L-arginine per full serve, and none of it comes with a stimulant attached, so it works equally well as a stand-alone session starter or as an add-on to whatever pre-workout you already run. A few other details are worth knowing before you buy:

• Only 50 calories and 12g of carbohydrate per full capful, light enough to add on top of a meal or another supplement without derailing your daily macros.
• A measured liquid capful (1 fl oz), so there's no scoop to level off and no powder clumping in a humid bathroom cabinet.
• Just 3mg of sodium per serving, which leaves room to dial in your own electrolyte mix separately rather than inheriting a fixed sodium load.

Getting the most from it

Take a full capful of Gaspari Proven Pump around 20 to 30 minutes before your first set, giving the L-citrulline and L-arginine time to convert and support blood flow before you're under load. On a lighter training day, a half capful is usually enough for a mild pump without the full 50 calories. Because it carries no stimulants, it sits comfortably next to a caffeine-based option from the pre-workout range, letting you dial stimulant intake and pump support up or down independently, or you can pair it with a dose from the creatine range for lifters chasing power output and vascularity in the same session.

The 12g of vegetable glycerol works best with adequate fluid intake, so pair your capful with your usual training-day water, or an option from the electrolytes range if you're training somewhere hot or sweating heavily. Gaspari Proven Pump - Lemon Drop is also a practical fit for a second session later in the day, when you want the blood flow and fullness of a pre-workout without adding to your caffeine total from an earlier stim-based dose.
