Gsn Amino C is a supplement that its formula contains all the complete amino acids that the body needs collaborating in muscle building for athletes. Amino acids are the basic units that make up proteins. There are twenty different amino acids that are classified into two main groups: essential and non-essential. The former cannot be synthesized by the body, so they must be supplied by the diet, while the nonessential ones are synthesized in our body. The essential amino acids are phenylalanine, isoleucine, leucine, lysine, methionine, threonine, and valine tryptophan. These eight amino acids are vital for the proper functioning of the body and must be provided daily in our diet, so that if one of these essential amino acids were missing in our body, the manufacture of body proteins would stop. It is recommended to take divided into 2 or 3 shots. They have not been described.
