I'm surprised more bodybuilders don't juice. Way more beneficial than a protein shake IMO with all the enzymes (aminos.)
My usual is: carrot, apple, celery, broccoli, kale, spinach, and parsley with a little lemon juice.
Amino acids are organic compounds made of carbon, hydrogen, oxygen, nitrogen, and (in some cases) sulfur bonded in characteristic formations. Strings of 50 or more amino acids are known as proteins, large molecules that serve the functions of promoting normal growth, repairing damaged tissue, contributing to the body's immune system, and making enzymes. The latter are a type of protein that functions as a catalyst, a substance that speeds up a chemical reaction without participating in it. Catalysts, of which enzymes in the bodies of plants and animals are a good example, thus are not consumed in the reaction.
