Reginator

Reginator (also known as EAAlpha) is a patented, vegan-friendly amino acid formulation consisting of nine essential amino acids plus arginine. Developed over 20 years at the University of Arkansas for Medical Sciences, it is designed to stimulate muscle protein synthesis and increase serum insulin-like growth factor 1 (IGF-1) levels. The supplement is positioned as a highly efficient anabolic activator, with clinical data suggesting that low doses can outperform significantly larger quantities of whey protein in promoting muscle health and cellular recovery. It is primarily targeted at adults experiencing age-related declines in growth hormone and IGF-1, and has been evaluated in numerous human clinical trials for its efficacy in supporting muscle mass and metabolic health.
