Although study continues, it may be postulated that “enriching” the blood with the Myogence formula of amino acids aids the exercising body in at least three ways. First, readily available substrates in the blood decrease the workload on the liver to otherwise produce them thus reducing caloric energy utilized by the liver during exercise resulting in more caloric energy available for activity.  Second, ready supply of amino acids and polypeptides as delivered by Myogence may facilitate skeletal muscle repair. More rapid skeletal muscle repair may provide greater skeletal muscle availability for strength and stamina related to activity as well as recycling muscle as energy supply. Third, substrates presented by Myogence appear to have a positive impact on cardiovascular performance. Studies have indicated numerous relationships between amino acids and cardiovascular performance. Some more intriguing studies have cited improved stroke volume and vascularization. Theories have been presented referencing positive impact on the “nitrogen puff” exchange and on symbiotic relationship between nutrient substrate availability and smooth muscle similar to that hypothesized related to skeletal muscle.
