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.†

Beta-Alanine

Beta-Alanine helps to regulate the lactic acid build up in the muscle to reduce exercise fatigue. This means you can push harder and hit more reps in the gym. Beta-Alanine is also responsible for the tingle sensation that most users experience when taking a pre-workout. But don’t worry, it goes away after a few minutes.†

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.†

Taurine

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

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. N-Acetyl Tyrosine is more bioavailable and more soluble in water, which means your body can absorb and use it better.†

Acetyl L-Carnitine

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.†

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. †

L-Theanine

L-Theanine is an amino acid known for its calming effects- it works by helping take the edge off any pre-workout jitters and supporting focus, which is why its important when pairing it with caffeine, so you're not only energized, but also dialed-in. †

Natural Caffeine from Camellia Sinensis Extract

Natural Caffeine from Camelia Sinensis Extract (green tea), is absorbed more gradually, helping you stay energized and focused without sudden jolt or crash. It provides a smoother, longer-lasting energy thanks to compounds like L-Theanine that comes along with it.†

Natural Caffeine from Coffee Arabica Extract

Natural Caffeine from Coffee Arabic Extract provides a quick pick-me-up without the harsh spike, helping you feel alert and ready right away. Like Caffeine Anhydrous, it offers a more immediate boost of energy, but with a smoother finish. These 3 sources of caffeine combined ensure you get an immediate, but sustained energy boost for hours. †

Caffeine Anhydrous

Caffeine Anhydrous is a concentrated form of caffeine that’s all about quick, powerful energy. Caffeine Anhydrous is essentially caffeine without water, so it’s absorbed faster, giving you that boost right when you need it. It's perfect for firing up your energy, focus, and motivation at the start of your workout. It helps you power through tough sets, increases endurance, and keeps you mentally sharp without going overboard. †

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.†

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.†

Himalayan Rock Salt

Himalayan Rock Salt is loaded with essential minerals like magnesium, calcium, and potassium, all of which help with hydration and electrolyte balance. Keeping your muscles hydrated during intense training is crucial for optimal performance and helps to prevent cramps.†
