BCAA is three of the eight essential amino acids in human body, including leucine, isoleucine and valine. BACC is the main component of skeletal muscle amino acids, reaching 1/3. Skeletal muscle, as we all know, is the muscle of the body. Therefore, there is no doubt that BACC has a certain effect on muscle synthesis.

However, the role of BCAA is to respond to the action of "muscle synthesis" at the hormone level, not the action itself. If only BCAA is ingested, the efficiency of muscle synthesis cannot be improved.

From a chemical point of view, BCAA is like a catalyst in chemical reactions. With it, the reaction will be accelerated. But only it, without other elements, is impossible to complete this reaction.
