However, no studies have yet been reported linking low serum GHK levels with specific aging processes or age-related disease

Research has demonstrated that GHK-Cu treatment increases production of collagen (particularly type I and type III collagen, the predominant structural collagens in skin and connective tissues), glycosaminoglycans (including hyaluronic acid, which provides hydration, volume, and biochemical signaling in skin), decorin (a small proteoglycan involved in collagen fibril organization and growth factor regulation), and other matrix molecules critical for tissue structure and function

Perhaps most significantly, GHK-Cu offers systemic regenerative benefits beyond hair when administered via injection
