Natural Sweeteners and Flavors. The Science Behind the Size: Product: a fast absorbing anabolic liquid amino acid product that has, per serving, 15 grams (15,000mg) of high quality branched chain, peptide-bonded, and free amino acids; stress B-complex vitamins; energizing complex carbohydrates; and pure crystalline fructose. Result: protein in its most easily digested absorbable and utilizable form to maximize muscle growth and optimize protein synthesis. Science: research shows that when taken orally; peptide-bonded amino acids increase nitrogen retention better than free form amino acid mixtures for optimum muscle growth.
