ARGININE is considered a semi-essential amino acid, produced normally in the body, but sometimes your body needs more than what is available. Food sources such as peanuts and almonds are natural sources, but for those looking to enhance athletic performance or increase lean muscle mass, it is difficult to derive the amount required by the body for optimal results from food sources. Mix one rounded teaspoon (5 grams) in water or juice 1-3 times daily. For training sessions and athletic events, take approximately 30 minutes prior to training. At times when you are not training, mix one rounded teaspoon (5 grams) of it upon waking and/or prior to sleeping.
