Optimum Nutrition Threshold Muscle Fatigue Fighter Fruit Fusion Description
During exercise, and especially 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, Threshold is designed to help boost your intramuscular buffering system so that you can train harder, longer.
Add 1 scoop to a glass or shaker cup filled with 6-8 oz of cold water or your favorite beverage. Mix or shake thoroughly for 15-20 seconds or until powder is completely dissolved.
Consume one serving first thing in the morning and a second serving approximately 30 minutes before your workout (or mid-afternoon on a non-training days).
Tips: The first few times that you use it, Threshold may cause a tingling sensation on your skin. With continued use, the intensity of the sensation will decrease or disappear. For best results, use Threshold continuously for at least 8 weeks.
