Dietary Supplement. Anabolic Liquid Mass. The Science Behind the Size: Product-A fast absorbing anabolic liquid amino acid that has, per serving, 15 grams (15,000 mg) 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.
