Syntrax line of protein supplements are a source of low cost and good quality whey protein, as it is rich in essential amino acids, responsible for increasing energy and helping in muscle reconstruction.

It contains glutamine, which helps in recovery after training; L-arginine, which dilates the blood vessels and, consequently, allows the nutrients to reach the muscles more quickly; and BCAA.
