Performax Labs VasoMax Grand Pre is the ultimate pump pre-workout on the market, formulated to enhance vasodilation, blood flow, cellular swelling, and pumps from multiple fronts. Priming the pump is a whopping 10,000mg of pure L-Citrulline at the full 2-scoop serving, one of the most effective and reliable vasodilators available — activating endothelial nitric oxide synthase (eNOS) to increase nitric oxide levels and relax blood vessels. Layered on top: Nitrosigine® and HesperiPump™, two premium branded ingredients that work through complementary arginine and hesperidin pathways to compound the nitric oxide response, plus AmentoPump™ for increased cGMP production and Phyto-C® antioxidant support to prolong NO levels in the body. To address the water-based dimension of the pump, VasoMax Grand Pre includes 2,500mg of Betaine Anhydrous, Taurine, and Pink Himalayan Salt for cell volumization and muscular fullness. AstraGin® ties it all together, enhancing absorption of every pump ingredient in the formula. Far too often, pump formulas are nothing but some underdosed mixture of Citrulline, Arginine, and Glycerol Monostearate — VasoMax Grand Pre utilizes a multi-tiered approach instead. 100% stimulant-free. Pump-only formula — no nootropics, no beta-alanine tingles, just pumps. 40 servings (1 scoop) or 20 servings (2 scoops). Flavors: Rocket Pop, Tropical Fruit Punch.†

10,000mg Citrulline — At the Very Top of the Effective Range
Citrulline benefits start at as little as 3,000mg, but the sweet spot for pump and performance effects sits at 4,000-8,000mg — Performax Labs gives users 10,000mg at the full 2-scoop serving, about the maximum reasonably suggested in a single serving. Unlike Citrulline Malate (which delivers only about two-thirds actual Citrulline by weight, with the remainder being Malic Acid), VasoMax Grand Pre uses pure L-Citrulline — meaning the full 10,000mg is active Citrulline, not diluted. Citrulline is the precursor to Arginine, and once converted in the kidney, it activates eNOS to trigger the nitric oxide response responsible for vasodilation and increased blood flow to working muscle.†
Nitrosigine® and HesperiPump™ — Two Distinct Arginine and Flavonoid Pathways
Nitrosigine® is a patented complex of arginine, inositol, and potassium silicate, clinically studied to promote nitric oxide production for improved blood flow, focus, and energy — it works in combination with Citrulline to increase circulating Arginine levels, since Arginine is the direct substrate eNOS uses to produce nitric oxide. HesperiPump™ takes an entirely different route to the same goal: a Citrus aurantium extract standardized to α-glucosyl-hesperidin that metabolizes into hesperetin, a flavonoid that directly activates eNOS through its own independent mechanism. Stacking these two branded ingredients on top of 10g Citrulline means VasoMax Grand Pre is attacking nitric oxide production through three separate, complementary pathways rather than relying on Citrulline alone.†
AmentoPump™ and Phyto-C® — Extending and Protecting the Pump
AmentoPump™ promotes nitric oxide production by increasing cyclic guanosine monophosphate (cGMP) — the downstream signaling molecule that nitric oxide itself works through to relax vascular smooth muscle. By supporting cGMP directly, AmentoPump™ adds a fourth distinct mechanism to the nitric oxide support system. Phyto-C® rounds out the pump complex as an antioxidant — nitric oxide is naturally short-lived in the body, broken down relatively quickly by oxidative processes, and Phyto-C®'s antioxidant activity is included specifically to help prolong the nitric oxide levels the rest of the formula works to produce, extending the duration of the pump rather than just its initial intensity.†
Betaine, Taurine, and Pink Himalayan Salt — The Water-Based Pump
Nitric oxide-driven vasodilation is only one half of what produces a full, hard pump — the other half is cell volumization, the osmotic process that draws water into muscle cells themselves. Betaine Anhydrous at 2,500mg is dosed at what's considered an ideal amount for this ingredient — proven to improve strength and power output in the gym alongside its cell-hydrating osmolyte properties. Taurine supports muscle contraction function and adds its own osmolyte activity. Pink Himalayan Salt provides the sodium and trace mineral electrolyte content that supports fluid retention within muscle tissue, complementing Betaine and Taurine's cell volumization effect. Together, these three ingredients address the "water-based pump" dimension that pure vasodilators like Citrulline and Nitrosigine don't cover on their own.†
AstraGin® — Making Every Other Ingredient Work Harder
AstraGin® is a trademarked combination extract of Panax notoginseng and Astragalus membranaceus, shown to enhance the absorption of micronutrients by supporting nutrient transporters in the gut. At the substantial combined ingredient load in VasoMax Grand Pre — 10g Citrulline alone is a significant amino acid dose — AstraGin's inclusion is specifically meant to tie everything together, ensuring more of each pump-enhancing ingredient is actually absorbed rather than partially lost in digestion.†
A True 40/20 Serving Product
VasoMax Grand Pre is built as a genuine 40/20 serving unit — a full 22g double-scoop serving delivers the complete formula described above, while a single 11g scoop delivers half of every dose for a lighter pump experience or for stacking with a separate stimulant pre-workout. This flexibility means most users can reasonably get 40 servings out of one container at the single-scoop dose, or 20 servings at the full recommended 2-scoop dose — a genuinely honest labeling approach compared to products that only technically achieve their stated serving count at a minimal, sub-effective dose.†
Why This Is a Pump-Only Formula
VasoMax Grand Pre has been formulated to possibly provide an amazing pump without the other non-stimulant sensations like nootropics or Beta-Alanine — no tingling, no jitters, no cognitive stimulant layer, just a concentrated, multi-pathway nitric oxide and cell volumization system. This makes it a natural stacking partner for any stimulant pre-workout (adding pure pump on top of an existing energy and focus formula) or a standalone option for anyone who specifically wants a big pump without any accompanying sensory effects.†
Frequently Asked Questions
Should I take 1 scoop or 2 scoops?
2 scoops (22g) delivers the full formula described on the label, including the full 10,000mg Citrulline and 2,500mg Betaine doses. 1 scoop delivers half of everything — a reasonable starting point to assess tolerance, or for stacking with a separate stimulant pre-workout without doubling up on total pump ingredient volume.†Can VasoMax Grand Pre be stacked with a stimulant pre-workout?
Yes — since it's 100% stimulant-free, VasoMax Grand Pre is specifically well-suited to stack with any caffeinated pre-workout to add a dedicated, heavily-dosed pump layer without adding to your stimulant intake.†Why does VasoMax use pure Citrulline instead of Citrulline Malate?
Pure L-Citrulline delivers 100% of the stated weight as active Citrulline, while Citrulline Malate (commonly used at a 2:1 ratio) delivers only about two-thirds actual Citrulline, with the rest being Malic Acid. At 10,000mg, VasoMax Grand Pre's pure Citrulline provides more total active Citrulline than an equivalent stated weight of Citrulline Malate would.†Is VasoMax Grand Pre appropriate for tested athletes?
Based on the disclosed formula — L-Citrulline, Betaine Anhydrous, Nitrosigine, HesperiPump, Taurine, Pink Himalayan Salt, AmentoPump, Phyto-C, and AstraGin — VasoMax Grand Pre does not contain any compounds prohibited by WADA or NCAA. Zero stimulants, no banned compounds. Tested athletes should review the complete label and verify with their governing body as standard practice.†
How to Take Performax Labs VasoMax Grand Pre
Consume 1-2 scoops in 12-16oz of water 30 minutes before your workout. Start with 1 scoop to assess tolerance, or if stacking with a stimulant pre-workout. Use the full 2-scoop dose for maximum pump effect. Not for use by persons under 18 years of age. Consult a physician before use if pregnant, nursing, or taking medications. Do not exceed the recommended serving. California Prop 65 Warning applies.†
