Muscle Fatigue Fighter. With Histidine and Electrolytes. 1.6g Beta Alanine. 0g Sugar. 75 Servings. The True Strength of Muscle Stamina: During high-intensity training, glucose and glycogen are broken down for energy. In the process, hydrogen ions (H+) are also produced within the muscles. H+ accumulation causes the muscles to become more acidic and ultimately leads to fatigue. Packed with Beta-Alanine, Histidine, and Phosphates our Beta-Alanine Powder formula is designed to help boost your intramuscular buffering system so you can train harder, longer.
