Caffeine Anhydrous (200 milligrams)
Caffeine is a powerful stimulant that enhances both physical and mental performance, making it a key ingredient in pre-workout supplements. By stimulating the central nervous system (CNS) and blocking adenosine receptors, caffeine reduces fatigue, boosts alertness, and sharpens mental focus. It also improves endurance by increasing fatty acid availability for fuel, sparing glycogen stores, and delaying fatigue, while enhancing strength output and reducing perceived exertion for heavier lifts and more intense sets.

Carnosyn® Beta Alanine (1500 milligrams)
Beta-alanine is an amino acid that helps buffer hydrogen ions (H+) in muscles, reducing the buildup of lactic acid during intense exercise, which can cause muscle fatigue. It combines with histidine to form carnosine, a compound that delays muscle failure by reducing acidity, allowing you to push through more reps, sets, and overall training volume. This leads to improved strength endurance and better overall workout performance.

Citrulline (5000 milligrams)
When ingested, citrulline converts into arginine, which boosts nitric oxide levels and leads to vasodilation—widening blood vessels. This increases blood flow to muscles, improving oxygen and nutrient delivery, which enhances performance and accelerates recovery. With better blood flow, essential nutrients like amino acids and glucose reach muscles for repair and growth, while efficient oxygen delivery helps delay fatigue during intense workouts. Citrulline amplifies the pump, reduces muscle fatigue, and improves endurance, allowing you to work harder and longer, optimizing each rep and set.

Lion's Mane (250 milligrams)
Lion's Mane is a medicinal mushroom renowned for its cognitive benefits. It stimulates the production of nerve growth factor (NGF), which supports neuron health and regeneration, leading to improved focus, mental clarity, and overall cognitive function. By reducing mental fatigue, Lion's Mane helps keep you sharp and motivated throughout your workout, ensuring not only physical energy but also enhanced mental clarity.
