History and Usage: When it comes to ingesting amino acids orally, the exact mechanisms or kinetics involved in the digestion and absorption are not fully understood. What is known is that, once ingested, amino acids must pass through the highly destructive stomach-acid medium; thus, getting effective ratios of BCAA's and EAA's into the blood simultaneously can become difficult and expensive. To get blood levels of these highly effective amino acids into an optimal range, many athletes resort to a mass-absorption strategy (i.e., taking more than what's needed because absorption is restricted). Optimizing the fate of these key amino acids was the impetus behind Growth Factor - using esterification science to protect amino acids from stomach destruction. Uses Highest Quality Ethyl Ester Technology. Includes a BCAA and EAA Infused Hyper-Growth Complex. Supports Maximum Utilization and Absorption. May Support Anabolism and Aid in Crushing Catabolism. Designed to Support Recuperation, Recovery and Repair. Aids in Muscular Endurance. Stomach Friendly.
