How It Works
Nexus PER4M works through a targeted combination of performance-enhancing ingredients designed to support physical strength, stamina, and mental clarity. L-Citrulline drives nitric oxide synthesis, expanding blood vessels to supply active muscles with key nutrients and oxygen for full muscle fullness.
To complement the physical pump, Beta-Alanine supports intramuscular carnosine levels, delaying the onset of fatigue so you can complete more reps under heavy load. Concurrently, the caffeine and mental focus blend stimulates the central nervous system to keep your energy elevated and your focus locked in from start to finish.
Recommended Use
Mix 1 scoop with 300–400 ml of cold water and consume 20–30 minutes prior to your workout. To assess individual tolerance, start with half a scoop. Do not exceed 1 scoop in a 24-hour period, and avoid taking within 5–6 hours of sleep.
Nexus Sports Nutrition PER4M Pre-Workout Frequently Asked Questions
What is Nexus PER4M Pre-Workout and what makes it unique?
Nexus PER4M is a premium, comprehensive pre-workout formula engineered with 17 high-purity, active ingredients dosed to clinical efficacy. Rather than relying entirely on high caffeine loads, PER4M balances explosive energy, a multi-pathway muscle pump matrix, and clean, deep nootropic focus—allowing New Zealand athletes to unlock peak physical output without experiencing a sudden post-workout crash.
What are the exact macronutrient and active ingredient metrics per serving?
PER4M utilizes a fully transparent, dual-tier dosing structure. A standard single scoop (8g) provides clean daily energy, while a maximum hardcore double scoop serving (16g) delivers a heavily loaded performance blueprint:
L-Citrulline Malate + L-Norvaline: A heavy-duty combination (6,000mg L-Citrulline + 200mg L-Norvaline) that works in synergy to maximize nitric oxide production and inhibit its breakdown for dense, long-lasting muscle vascularity.
Beta-Alanine & Taurine: 3,200mg of Beta-Alanine paired with 1,000mg (1g) of Taurine to support greater muscular endurance and buffer lactic acid build-up during high-intensity sets.
Explosive Energy Blend: Powered by a strong caffeine anhydrous base enhanced by English Walnut Extract (200mg) and Messembrine (30mg) to provide immediate, sustained physical drive.
Tunnel-Vision Cognitive Matrix: Features 250mg of Alpha GPC, 500mg of L-Tyrosine, and L-Theanine to lock in razor-sharp mental focus and mood elevation under heavy training stress.
What is the role of L-Norvaline in the PER4M pump matrix?
While standard pre-workouts only include Citrulline to spark nitric oxide production, your body naturally produces an enzyme called arginase to limit and break down your muscle pumps. Nexus explicitly solves this by adding 200mg of L-Norvaline, a specialized amino acid that acts as a natural arginase inhibitor. By blocking the breakdown of nitric oxide, it allows blood vessels to remain dilated longer, resulting in significantly fuller, skin-splitting muscle pumps that persist long after you finish your last set.
Will Nexus PER4M cause a jittery feeling or a post-workout crash?
No. Nexus masterfully avoids the severe crashes common with lower-tier pre-workouts. By pairing its rapid caffeine release with premium stabilizing nootropics—specifically Alpha GPC, L-Theanine, and natural B Vitamins—it provides a smooth, clean wave of physical energy that tapers off gradually, allowing you to transition into your post-workout day with zero brain fog.
Is Nexus PER4M suitable for beginners or individuals sensitive to stimulants?
Yes, thanks to its flexible formulation. If you are a beginner, a single-mum looking for an afternoon boost, or sensitive to caffeine, you should start with a half-scoop or single scoop (8g serving) to comfortably assess your personal tolerance. Advanced trainers demanding maximum, high-stimulant intensity can safely scale up to the full 2-scoop hardcore serving (16g). Do not exceed 2 scoops within a 24-hour window.
How many servings are inside a standard tub?
A standard full-size tub of Nexus PER4M contains an 400g net weight. This yields exactly 50 single-scoop standard servings, or 25 maximum-strength, full 2-scoop hardcore servings, delivering elite long-term value for your weekly gym routine.
What are the top-selling customer flavors available at Sprint Fit?
Nexus is highly acclaimed across Australasia for crafting incredibly refreshing, sweet flavor profiles that taste exactly like premium confectionery. Top-voted, fast-selling favorites in New Zealand include Red Sour Straps, Blue Sour Straps, Grape, and Psyclone. The powder is completely instantized to dissolve perfectly clear in cold water with zero chalky residue.

Red Sour Straps
Red sour straps is absolutely delicious, I normally avoid anything with “sour” in the title it’s not sour at all, I’ve tried many flavours but this is by far the best!!! I use it as a wake up booster before work (I work night shift from midnight) it gives me a huge boost, also great to get the muscles going before hiking

Easily the best pre workout. Have spend far too long researching ingredients and spending heaps on different formulas. Simple facts of this are that all the ingredients are dosed to clinically effective doses. That is gold these days. Big pumps, massive deep sustained focus. Pure clean king lasting energy and a good dose of cognitive power. Game changer.
