Packed with 1,000mg, Arginine alpha-ketoglutarate forms when two arginine molecules combine with one molecule of alpha-ketoglutarate. Found in Edge Pump, this combination improves the stability of arginine. L-Arginine is the biological precursor of nitric oxide (NO), and it stimulates the secretion of the growth hormone, leading to the production of insulin-like growth factor 1 (GF-1). GF-1 enhances protein synthesis, increasing muscle development.
