        If you work out hard, these peptide bonded amino acids can be up to 16 times more effective for muscle repair than whole food sources. MASS begins absorbing in minutes - whole food can take 4 hours.
        The Amino / Nitrogen / Total Nitrogen ratio in Beverly Mass Aminos is the key to how good an amino acid supplement really is.  Nitrogen rating is what most protein scientists use to determine how much muscular weight gain a particular protein can facilitate. Beverly MASS has the highest nitrogen rating of any amino acid supplement.
        To provide any real benefits, an amino acid supplement must be composed of pancreatic (enzyme) digests of protein and peptide-bonded amino acids, readily available for your body to use. The enzyme breakdown of the amino acids does not degrade the aminos like the typical "acid bath" breakdown used by other supplement manufacturers.
