NOX Pump Ultimate - 5g Citrulline + 5g Betaine stim pump pre-workout

DY Nutrition NOX Pump Ultimate delivers 5000mg L-citrulline, 5000mg betaine anhydrous, 3200mg beta-alanine, 1500mg L-ornithine, 1000mg L-tyrosine, 350mg caffeine anhydrous, 300mg juniper berry extract, 200mg Zynamite mango leaf extract, 50mg AstraGin and 10mg BioPerine per 20g serving. The 400g tub provides 20 sessions.

L-citrulline at 5g drives nitric oxide production through the arginine-NO pathway, supporting vasodilation and training pump. Betaine anhydrous at 5g is dosed at the level studied for power output and muscle endurance effects. Beta-alanine at 3200mg delivers the studied dose for muscle carnosine buffering. L-ornithine supports the urea cycle and ammonia clearance during high-intensity effort, which contributes to reduced fatigue. Zynamite provides stimulant activity from the mangiferin fraction independent of caffeine, allowing total stimulant intensity without maximal caffeine escalation. AstraGin and BioPerine enhance bioavailability of the active stack.

NOX Pump Ultimate is the premium pre-workout in the DY Nutrition range, built around a fully dosed active stack rather than proprietary blending. The 350mg caffeine positions it in the high-stim category alongside Blood & Guts, but the different secondary ingredient stack - betaine, ornithine, Zynamite - gives it a different performance profile focused more on pump and power output than pure stimulant intensity. 20 servings from a 400g tub means this is a session-specific product rather than a daily lightweight pre-workout.

Built for experienced lifters, competitive bodybuilders and athletes who train at maximum intensity and want a fully dosed pump and performance stack. The 350mg caffeine dose and 3.2g beta-alanine are significant - not appropriate for caffeine-sensitive individuals or first-time pre-workout users. Should not be combined with additional stimulant products on the same session. No major allergens declared. Produced in a facility that may handle milk, soy, egg and gluten.

Stim-free pump alternative: XL Nutrition Purge Pump 300g delivers 4g L-citrulline malate, 2.5g betaine, 1g taurine and 1g beetroot powder per 10g scoop (stim-free) at £11.99 for 30 servings (just £0.40 per scoop). That's about 68% less per serving than this product's £1.25/serving cost.
