Peptides are short chains of amino acid monomers that are linked by some peptide (amide) bonds. Peptides are different from proteins on the basis of size and as an arbitrary benchmark, it can be understood to have around 50 or even fewer amino acids. The human body is using those short amino acid chains to secrete the Growth Hormone (GH), which is already being stored in the body. Very often, supplement companies are breaking down proteins into peptides because in this way, the product is easier to get absorbed. Generally, peptides are known to boost testosterone or Human Growth Hormone (HGH FRAGMENT), which can help with fat loss, muscle growth and many others.
