Enhanced Labs - Maximus Pump

Enhanced Labs Maximus Pump: Stim-Free Pre-Workout

Maximus Pump is a fully caffeine-free pre-workout designed around four performance pillars—pumps, strength, endurance, and focus—using 17+ synergistic ingredients and 8 patented compounds to deliver a comprehensive training experience without stimulants.

No caffeine means no jitters, no crash, and no sleep disruption—making it equally effective for early morning sessions, late-night training, or stacking with a separate stimulant pre-workout on heavy days.

Four Performance Pathways Explained

Rather than relying on caffeine to drive every aspect of performance, Maximus Pump addresses pumps, strength output, endurance, and cognitive focus through dedicated ingredient groups that work simultaneously across each training session.

Pump & Vascularity

L-Citrulline (8g), Nitrosigine® (1.5g), HydroPrime™ Glycerol (3g), Beet Root Powder (500mg), and L-Norvaline (100mg) work together to support nitric oxide production and promote enhanced blood flow and muscle fullness during training.

Strength & Metabolic Support

Vitamins B3 and B12 alongside ElevATP® (150mg) and Himalayan Pink Salt (100mg sodium) help support cellular energy production and electrolyte balance to promote sustained power output throughout the session.

Endurance & Fatigue Resistance

Beta Alanine (3.2g) and Betaine Anhydrous (3g) help buffer lactic acid accumulation, while PeakO2® (1g) and EndoFlo™ (200mg) work to support oxygen utilization and help maintain training capacity over time.

Focus & Mind-Muscle Connection

GeniusPure™ Alpha GPC 90% (150mg), NeuroRush™ (100mg), and Huperzine Extract (10mg) promote cognitive sharpness and help maintain concentration throughout training without stimulant-driven anxiety.

Full Ingredient Profile

Pump & Blood Flow Compounds

• L-Citrulline 8g: Full clinical dose to support nitric oxide synthesis and promote muscular blood flow and endurance.
• HydroPrime™ Glycerol 65% — 3g: Patented high-purity glycerol that promotes hyperhydration in muscle tissue for increased fullness and pump.
• Nitrosigine® 1.5g: Patented inositol-stabilized arginine silicate shown to support arginine levels and help maintain nitric oxide production before and during exercise.
• Beet Root Powder 500mg: Natural source of dietary nitrates to further support blood flow pathways.
• L-Norvaline 100mg: Arginase inhibitor that helps extend nitric oxide activity by reducing arginase breakdown.

Strength & Energy Support

• Betaine Anhydrous 3g: Promotes cellular hydration and supports strength and power output at clinical dosing.
• ElevATP® 150mg: Patented ancient peat and apple extract blend studied for its role in supporting intracellular ATP production.
• Vitamin B3 (Niacin) 20mg NE (125% DV): Supports energy metabolism and promotes healthy blood flow through vasodilatory mechanisms.
• Vitamin B12 (Methylcobalamin) 250mcg (10,417% DV): Active form of B12 to support energy production and red blood cell formation.
• Sodium (Himalayan Pink Salt) 100mg: Electrolyte support for hydration balance and sustained energy during extended sessions.

Endurance & Resilience

• Beta Alanine 3.2g: Full clinical dose to help buffer muscle acidity and support muscular endurance during high-intensity efforts.
• PeakO2® 1g: Patented adaptogenic mushroom blend (Cordyceps, Reishi, King Trumpet, Shiitake, Lion's Mane, Turkey Tail) to help support oxygen utilization, VO2 max, and training capacity.
• EndoFlo™ 200mg: Patented blend of Mangifera indica, Kaempferia parvifloria, Ginkgo biloba, and Pinus massoniana to promote endothelial function and blood flow efficiency.
• S7® 50mg: Patented plant-based antioxidant complex (Green Coffee, Green Tea, Turmeric, Tart Cherry, Blueberry, Broccoli, Kale) to help reduce oxidative stress during training.

Focus & Cognitive Support

• GeniusPure™ Alpha GPC 90% — 150mg: Premium high-bioavailability choline source that promotes acetylcholine production to support focus and mind-muscle connection.
• NeuroRush™ 100mg: Patented Coffee arabica fruit extract studied for its role in supporting cognitive performance and mental clarity.
• Huperzine A Extract 10mg (std. 1%): Acetylcholinesterase inhibitor that helps sustain acetylcholine levels to support prolonged mental sharpness during training.

Synergistic Formula Design

Maximus Pump is structured so each performance layer reinforces the others: the pump complex drives blood delivery, the endurance stack keeps muscles working efficiently, the strength support feeds cellular energy, and the nootropic layer maintains the cognitive output needed to capitalize on the physical effect.

Pump Synergy Deep Dive

L-Citrulline raises plasma arginine; Nitrosigine® extends and stabilizes that arginine pool; HydroPrime™ promotes intracellular water retention; Beet Root adds dietary nitrate substrate; and L-Norvaline blocks the enzyme that would otherwise break down arginine—creating a full-circle pump system at every step of the nitric oxide pathway.

Stim-Free Versatility

Because Maximus Pump contains zero caffeine, it can be used at any time of day. On heavy training days, Enhanced Labs recommends stacking it with Maximus Stim to layer stimulant-driven energy on top of the pump and endurance foundation already in place.

Recommended Use

Standard Protocol

Mix 1 scoop (20.53g) in 6–8 oz of cold water and consume 15–30 minutes before training. No loading phase required.

Stacking Option

On high-intensity training days, Maximus Pump can be stacked with a stimulant-based pre-workout for layered energy and pump benefits. Enhanced Labs recommends pairing with Maximus Stim for the full dual-pre-workout experience.

When to Take It

• Evening training: Ideal caffeine-free option to protect sleep quality while still hitting performance goals.
• Morning training: Use standalone or stack with stimulants for maximum effect on heavy days.
• High-frequency athletes: Works daily without caffeine tolerance buildup affecting results.

Who Maximus Pump Is For

• Stimulant-sensitive athletes: Caffeine responders who want full pre-workout performance without jitters or anxiety.
• Evening lifters: Those who train after 5pm and can't afford sleep disruption from caffeinated products.
• Stim stackers: Athletes who want to add pump and endurance on top of their existing stimulant pre-workout.
• Physique athletes: Bodybuilders and competitors prioritizing maximum vascularity and muscle fullness.
• Endurance athletes: Runners, cyclists, and sport athletes who benefit from the adaptogen and VO2 support components.
