L-Arginine Alpha Ketoglutarate (AAKG) is advertised as a Nitric Oxide increasing agent to improve results of exercise on muscles, improve protein synthesis generally, and growth hormone secretion. All of these assertions are rather vague and have at best limited scientific support, but it is considered a diet supplement and is known to be safe even at high doses so there is little regulation that applies.
