Peptide therapy is the targeted use of peptides to produce a specific therapeutic reaction in the body. Some peptides have been shown to assist with weight loss by stimulating the breakdown of visceral fat. They may also be utilised to reduce inflammation. Some peptides stimulate the production of human growth hormone and are utilised in anti-ageing therapies or to increase muscle mass. The body uses these proteins or peptides as signalling molecules for cell-to-cell communication allowing the body to turn on certain cell functions to trigger specific positive effects.
