Core Med Science Pre-Workout is a performance formula designed for the way real people actually train and live. 

The formula starts with 6,000 mg of L-Citrulline Malate (2:1), a gold-standard dose for supporting nitric oxide production, improved blood flow, and reduced fatigue. Beta-Alanine (3,000 mg) buffers the acid buildup that causes muscle fatigue mid-effort, while Betaine Anhydrous (2,000 mg) supports cellular hydration and power output.

Where Core Pre-Workout separates itself is in the focus stack. Alpha-GPC (300 mg) increases acetylcholine, the neurotransmitter responsible for attention, clarity, and mind-muscle connection. Most pre-workouts simulate focus with high caffeine. This formula delivers the real thing. Caffeine Anhydrous (100 mg) rounds out the stack with a purposefully moderate dose enough to sharpen alertness without spiking your heart rate or disrupting your sleep. Methylcobalamin B12 (500 mcg) supports energy metabolism at the cellular level, making this formula as useful before a workday as it is before a workout.

Transparent label. No proprietary blends. NSF Certified for Sport®.

Sustained Energy Without the Crash 100 mg of caffeine, roughly one strong cup of coffee which lowers perceived exertion and sharpens alertness without the anxiety or afternoon crash common in high-stim formulas. Paired with Methylcobalamin B12, it supports energy metabolism at the cellular level for clean, reliable energy whether you're heading to the gym or into a packed schedule.

Enhanced Blood Flow and Muscle Pumps 6,000 mg of L-Citrulline Malate increases nitric oxide production, supporting meaningful vasodilation, better oxygen and nutrient delivery to working muscles, and the fullness and pump that signals your body is performing the way it should.

Delayed Fatigue and Greater Endurance Beta-Alanine (3,000 mg) buffers the hydrogen ion buildup that causes the burning sensation during intense effort helping you push further before fatigue sets in. Betaine Anhydrous (2,000 mg) adds cellular hydration and power support, with research linking it to improved strength and endurance over time.

Sharper Focus and Mind-Muscle Connection Alpha-GPC (300 mg) is the ingredient most pre-workouts skip. It boosts acetylcholine in the brain, supporting attention, cognitive clarity, and the focused connection between mind and muscle that makes every rep count without adding more stimulants to the stack.

This product contains caffeine (100 mg per serving). Do not combine with other caffeine-containing products, medications, or stimulants. If you are sensitive to caffeine or beta-alanine, begin with a half serving to assess tolerance.

Beta-alanine may cause a temporary, harmless tingling sensation (paresthesia) on the skin. This is a normal physiological response and not cause for concern.

Keep out of reach of children. Do not exceed the recommended serving size. Store in a cool, dry place away from direct sunlight and moisture.
