CREATINE MONOHYDRATE Creatine Monohydrate (5 grams)
Creatine monohydrate is a naturally occurring compound found in muscle cells, derived from the amino acids arginine, glycine, and methionine. It plays a key role in producing adenosine triphosphate (ATP), the body’s primary energy carrier, helping support energy production during short bursts of intense activity. In addition to enhancing physical performance, creatine may support cognitive function by promoting ATP availability, which is important for maintaining focus, memory, and mental clarity during tasks that require mental and physical effort. PRE-WORKOUT 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. WHEY PROTEIN Whey Protein Concentrate (6 grams)
Whey protein concentrate offers several unique benefits compared to whey isolate, making it a versatile and cost-effective choice. It retains higher levels of immunoglobulins, which support immune health, and bioactive compounds like lactoferrin and alpha-lactalbumin that promote gut health, immunity, and antimicrobial properties. With minimal processing, whey concentrate preserves more natural nutrients and microfractions that aid muscle recovery and overall wellness. It also contains small amounts of fats and carbohydrates, including beneficial MCTs and phospholipids, which support energy metabolism, brain function, and the absorption of fat-soluble vitamins.

Whey Protein Isolate (13 grams)
Whey protein isolate is a highly purified protein source containing 90-95% protein by weight, making it ideal for those looking to maximize protein intake without added calories from fat or carbohydrates. Its minimal fat and carbohydrate content, including less than 1% lactose, makes it suitable for lactose-intolerant individuals or those on low-fat, low-carb diets. With faster absorption and fewer allergens due to extensive filtration, whey isolate is perfect for post-workout recovery, quickly delivering amino acids to support muscle protein synthesis. Its lean nutritional profile is excellent for building lean muscle while supporting fat loss.

Hydrolyzed Whey Protein (6 grams)
Hydrolyzed whey protein is a premium protein source that is enzymatically pre-digested, breaking down proteins into smaller peptides for faster absorption and improved muscle recovery. Its rapid delivery of amino acids makes it ideal for post-workout repair and growth. The hydrolysis process reduces allergens and lactose, making it easier to digest and suitable for those with dairy sensitivities. Like whey isolate, it is low in fat and carbohydrates, providing a lean option for muscle building and weight loss without extra calories.
