L-Leucine and Agmatine: L-Leucine is an essential amino acid that the body cannot synthesis on its own. Studies show that L-Leucine can help to both stimulate muscle protein synthesis and preserve muscle tissue. This must have muscle building product also contains Agmatine, which is a novel analog of L-Arginine. Agmatine shows greater potential than L-Arginine for nitric oxide synthase, as well as enhanced performance, endurance, and recovery. For optimal nutrient uptake, the patent-pending pH Balanced Alkaline Buffering System pH-Sorb has been added, which is designed to directly influence the acidity levels of the stomach for optimal digestion.
