Amino acids are the building blocks of protein, the primary component of muscle tissue. They play a vital role in numerous bodily functions, including:

• Muscle protein synthesis: Amino acids are essential for building and repairing muscle tissue, allowing you to increase muscle mass and strength.^[1]
• Hormone production: Certain amino acids serve as precursors for hormones that regulate growth, development, and metabolism.^[1]    
• Immune function: Amino acids support a healthy immune system, enabling your body to fight off infections and recover more quickly from training. ^[1]
• Energy production: While amino acids are primarily known for their role in muscle building, they can also serve as an energy source during intense exercise.^[1]

Elevate your performance and recovery with USN Hardcore All9 Amino

USN Hardcore All9 Amino is a premium blend of all nine essential amino acids (EAAs), the amino acids your body cannot produce on its own and must obtain from external sources such as food or supplementation. This carefully formulated blend gives your body the complete spectrum of EAAs needed to support optimal muscle growth, repair, and recovery.^[4]

Experience explosive workouts

• Boost endurance: Beta-alanine, a key ingredient in Hardcore All9 Amino, is a powerful performance enhancer. It works by increasing the production of carnosine within your muscles. Carnosine acts as a buffer, neutralising the build-up of lactic acid during intense exercise. This delayed onset of muscle fatigue allows you to push harder and longer, increasing your training volume and intensity. Additionally, Taurine contributes to enhanced muscle function and reduces fatigue, working synergistically with Beta-Alanine to maximise endurance. ^[6][2]
• Experience explosive pumps: Niacin acid (Vitamin B3) enhances blood flow to your muscles. This increased blood flow delivers vital nutrients and oxygen, leading to powerful muscle pumps and improved workout performance. Enhanced blood flow also helps remove metabolic waste products, reducing muscle soreness and accelerating recovery.^[7]
• Replenish electrolytes: Intense training can deplete your body's electrolytes, leading to dehydration, cramping, and decreased performance. Hardcore All9 Amino includes an electrolyte blend and coconut water powder to help replenish these crucial minerals, such as sodium, potassium, and magnesium, ensuring optimal hydration and performance during and after workouts.^[8]
• Reduce soreness and support recovery: L-glutamine, an abundant amino acid in muscle tissue, plays a crucial role in muscle recovery after exercise. It supports muscle protein synthesis, reduces muscle breakdown, and helps minimise muscle soreness and inflammation. L-glycine also contributes to muscle recovery and supports the production of creatine, further enhancing recovery and reducing post-workout discomfort.^[3]
• Build muscle faster: The nine essential amino acids fuel protein synthesis, building new muscle protein. By providing your body with a complete spectrum of EAAs, Hardcore All9 Amino supports optimal muscle growth, helping you achieve your fitness goals faster. Taurine further supports muscle protein synthesis and cell volume, enhancing muscle growth and recovery. ^[5][10]
