GPLC (Glycine Propionyl L- Carnitine) is a new form of carnitine with a high specificity for both skeletal muscle  and heart  tissue.  It has been reported that it possess benefits beyond those observed with typical L-carnitine.

In terms of performance, the increase in nitric oxide may be associated with an increase in blood flow to working skeletal muscle, which in turn may be associated with a greater delivery of oxygen and nutrients such as fatty acids, glucose, and amino acids. The increase in oxygen and nutrient delivery may increase work capacity during an acute bout of exercise due to greater ATP production.

In terms of recovery, greater nutrient delivery may facilitate glycogen resynthesis, as well as promote an anabolic environment (decreased proteolysis and increased protein synthesis).
