L-Citrulline

L-Citrulline is an amino acid that boosts nitric oxide production- the molecule responsible for dilating blood vessels. This process increases blood flow, which helps to improve nutrient transport and supply the muscles with fresh blood and oxygen during exercise, improving endurance, pumps and recovery. †

Betaine Anhydrous

Betaine Anhydrous helps maintain fluid balance in the cells by pulling water into your muscles, giving you better pumps. This helps to boost performance by improving cellular hydration, endurance and strength.†

Huperzine A

Huperzine A is a powerful nootropic that helps support mental clarity, focus, and memory. It works by preventing the breakdown of acetylcholine, a key neurotransmitter involved in learning and muscle activation. This means sharper mind-muscle connection, better reaction time, and improved cognitive performance during high-intensity training.†

L-Tyrosine

L-Tyrosine serves as a precursor to several important neurotransmitters, including dopamine and adrenaline- basically the stuff that keeps you feeling focused and in a good mood. It helps to reduce stress, sharpen your mind and keep you alert so you maximize your workouts.†

L-Taurine

L-Taurine helps regulate the balance of fluids in your cells, ensuring they stay hydrated and function properly. In the brain, taurine has calming effects, which can help with mood and mental clarity.†

Acetyl L-Carnitine HCl

Acetyl L-Carnitine HCl helps your body convert fat into energy, so you’re not just burning fuel- you’re tapping into stored fat as an energy source during your workout, giving you both mental and physical stamina. This form of L-Carnitine crosses the blood-brain barrier, meaning it can also support mental focus and clarity.†

N-Acetyl Tyrosine

Alpha GPC

Alpha-GPC helps increase acetylcholine, a key neurotransmitter that’s essential for memory, learning and muscle control. It is pure brain fuel, helping you stayed focused, keeping your mind sharp and your muscles engaged through each movement. †

Rhodiola Root Extract

Rhodiola is an adaptogenic herb known for its ability to help the body manage stress, fight fatigue, and stay mentally sharp. It works by supporting balanced cortisol levels and enhancing cognitive function, especially during physical and mental stress. That means more endurance, better mood, and the ability to push through even when the tank feels empty.†
