This protocol represents the most common approach among experienced users targeting specific injuries
First, it is an endogenous molecule: it circulates in human plasma at a concentration of roughly 200 ng/mL around age 20, declining to about 80 ng/mL by age 60, a fall that has been linked, at least associatively, to the general decline in tissue regenerative capacity with age
Once GHK-Cu binds to collagen or other extracellular matrix proteins, it remains localized and biologically active for 2472 hours before undergoing proteolytic degradation by matrix metalloproteinases and tissue peptidases

Collagen is the primary structural protein responsible for: Skin firmness Elasticity Tendon strength Ligament integrity Joint support Healthy fascia Blood vessel structure As collagen declines with age, the body becomes more vulnerable to: Wrinkles Skin laxity Tendon injuries Poor wound healing Ligament weakness Reduced tissue resilience Research suggests GHK-Cu may stimulate fibroblasts the cells responsible for producing collagen, elastin, and components of the extracellular matrix
