BCAA-Pro 5000 by SAN increases protein synthesis, stimulates nitrogen retention and most importantly, protects lean muscle tissue from the catabolic stress of heavy training and intense exercise. BCAA-Pro 5000 features b-Alanine which is a direct precursor to Carnosine. Carnosine is extremely effective in buffering hydrogen ions, which are generally elevated in exercising athletes. In essence, the addition of b-Alanine (and subsequently Carnosine) in BCAA-Pro 5000 is related to its effects on preventing your muscles from becoming too acidic during times of stress. Vitamin B6 has been added to enhance amino acid utilization directly into the muscle tissue. Additionally, each bottle bearing a SAN label has been HPLC tested and certified for purity and potency under stringent quality control guidelines (cGMP) that are set forth by the United States Food and Drug Administration.Nutrition Facts Serving Size 1 scoop Servings Per Container 100Amount Per Serving % Daily ValueL-Leucine 2,500 mgL-Valine 1,250 mgL-Isoleucine 1,250 mgBeta Alanine 750 mgVitamin B6 (as Pyridoxine HCI) 2 mg 67%*percent Daily Values are based on a 2,000 calorie diet.Other Ingredients: Citric Acid, Natural and Artificial Flavors, Aspartame (Contains Phenylalanine), Acesulfame-K.Directions: Take 1 scoop up to two times daily, one serving 30 minutes prior to your workout and another serving immediately after.*These statements have not been evaluated by the Food and Drug Administration.
