Peptide therapy is the targeted use of peptides to produce a specific reaction in the body. Peptides are chains of amino acids which are the building blocks of proteins. Some peptides have been shown to assist with weight loss by stimulating the breakdown of visceral fat. They may also be utilized to reduce inflammation. Some peptides stimulate the production of human growth hormone and are utilized in anti-aging therapies or to increase healthy physiologic muscle mass. Some are used to support the growth/repair of injured tendon, muscle and cartilage. They may also be used directly on the skin after medical micro-needling to support new facial collagen or new hair growth for scalp treatments. Peptides are typically administered through the skin as a subcutaneous injection. They can also be applied in a cream, a nasal spray or in oral form depending on the desired effect.
