ATP Science Endurance Plus — The Complete Endurance Pre-Workout

Endurance Plus is ATP Science's purpose-built endurance pre-workout — a comprehensive 46g per serve formula covering every energy and performance pathway needed for sustained high-intensity effort. Fast-acting carbohydrates for immediate fuel, Creapure® creatine for ATP regeneration, Citrulline Malate for blood flow and oxygen delivery, Beta-Alanine for acid buffering, Betaine for cellular hydration, Yerba Maté for natural caffeine, Pomegranate Peel Extract for antioxidant support, and a full electrolyte matrix. HASTA certified, Australian-made, dairy-free, gluten-free and nut-free. 27 serves, in stock at Payless Supplements.

Dosage & Timing

Mix 1 heaped scoop (approximately 46g) into 500ml of cold water in a shaker. Consume 20–30 minutes before training or at the start of your session. For longer sessions, begin sipping during the warm-up and continue through the first half of the session.

What's In Every 46g Serve — and Why It Matters

• Maltodextrin (15,700mg) + Dextrose (14,500mg) — a dual-source fast-absorbing carbohydrate combination providing 30.9g of carbs and 155 calories per serve for immediate and sustained energy during training. The combination of maltodextrin (longer chain) and dextrose (immediate) is the sports science-backed approach to maximising carbohydrate absorption during exercise without GI stress.
• L-Citrulline Malate 2:1 (3,000mg) — the full clinical dose for nitric oxide-driven vasodilation, improved blood flow and oxygen delivery to working muscle, and endurance support through the Krebs cycle via the malate component.
• Beta-Alanine (3,000mg) — the full clinical dose for muscle carnosine elevation and exercise-induced acidity buffering — delaying fatigue in high-intensity sustained efforts. (Note: the characteristic skin tingling is normal and harmless.)
• Creapure® Creatine Monohydrate (3,000mg) — German pharmaceutical-grade Creapure® at a meaningful dose for ATP energy system support. Including creatine in an endurance formula reflects the research showing creatine benefits repeated high-intensity efforts and overall work capacity, not just strength sports.
• Pregel Rice Starch / High Molecular Weight Rice Amylopectin (2,000mg) — a slow-release starchy carbohydrate source that complements the faster maltodextrin and dextrose for sustained carbohydrate availability through longer sessions.
• Yerba Maté Leaf Extract 4:1 (250mg) — a natural South American plant providing caffeine alongside theobromine and theophylline for a layered, smooth alertness and fatigue-reduction effect distinct from synthetic caffeine anhydrous.
• Betaine Anhydrous (250mg) — cellular hydration and endurance support, studied for improvements in total work volume and power output.
• Pomegranate Peel Extract 10:1 (113mg) — a concentrated source of polyphenol antioxidants for managing exercise-induced oxidative stress during prolonged training.
• Electrolytes — Sodium (130mg), Potassium (via Potassium L-Aspartate), Magnesium (via Magnesium Citrate) and Calcium (via Calcium Citrate) for hydration, muscle contraction and the prevention of performance decline from sweat losses.

HASTA Certified — Every Batch Tested

Endurance Plus is HASTA certified — independently tested for over 250 WADA-prohibited substances per batch. The standard required by NZ Rugby, NZ Olympic teams, Swimming NZ and many other sporting bodies. For athletes who compete in tested sport and need an endurance product they can take with confidence, this is one of the few that qualifies.

Who Should Use It

Endurance Plus is designed for athletes doing sustained high-intensity work — running, cycling, CrossFit, team sports, rowing, swimming and any training where energy availability and fatigue management are performance limiters. The 155-calorie carbohydrate load makes it appropriate for sessions of 45 minutes or more where carbohydrate fuelling matters. For shorter strength training sessions, the carbohydrate content may be more than needed — compare the Pre Plus pre-workout for a lower-carb, higher-stimulant option.
