Citrulline is a non-essential amino acid that is an important intermediate in the urea cycle, functioning along with Arginine and Ornithine to rid the body of ammonia, a byproduct of protein metabolism.

Yucca is a popular herb from a shrub which grows in the U.S desert Southwest. It has been used by Native Americans for hundreds of years for a variety of conditions.

Amino Acids For Positive Nitrogen Retention And Lean Mass! These are natural occuring sources of proteins which have been partially digested to make them more readily assimilable for human nutrition. The partial digestion splits the large protein molecules into small groups of amino acids called peptides. The amino acids are now called "peptide bonded." There are many ways to make a protein hydrolysate including acids and caustic treatment. However, for human nutrition Beverly has chosen the preferred method of using naturally occurring enzymes since they mimic the human digestive process and do not degrade the amino acids as do acids and/or caustics.MASSBy far the most superior quality peptide bonded amino tablet on the market. This very unique product is derived from casein, treated with pancreatic enzymes. Whereupon Mass is quickly absorbed, food bulk proteins serve as natural inhibitors of rapid absorption. Mass' balance of protein is exceptional, and to reach that balance we hav
