Labrada GlycoCarn nitric oxide booster is glycine propionyl L-carnitine HCL (GPLC), a propionyl ester of carnitine that is molecularly bonded to glycine. Studies suggest that 4.5 grams of GlycoCarn taken prior to training increases power output of muscles during exertion, buffers lactic acid buildup and significantly augments blood levels of nitric oxide resulting in increased muscle pumps and vasodilation. Increases nitric oxide. Improves blood flow. Increases performance. Improves recovery.
