How It Works
GHK-Cu is studied for its ability to bind copper and help deliver it into cells, where it may act as a signal that encourages fibroblasts to rebuild the skin's supportive matrix. In research settings, it has been explored for its potential to shift tissue toward a renewal and repair state rather than a breakdown state. Because individual goals and physiology differ, Dr. Rob tailors how and whether GHK-Cu fits into your plan.
The Science & Mechanism
GHK-Cu is the tripeptide glycyl-L-histidyl-L-lysine bound to a copper(II) ion, a complex that occurs naturally in human plasma and declines with age. The peptide acts as a high-affinity carrier that helps shuttle copper into and out of cells, where the metal serves as a cofactor for enzymes involved in collagen and elastin synthesis and antioxidant defense. In laboratory research, GHK-Cu has been observed to modulate the expression of a broad set of genes, generally upregulating those associated with tissue remodeling and DNA repair while downregulating signals linked to inflammation and fibrosis. It has also been shown in research settings to stimulate fibroblast activity and the synthesis of extracellular matrix components such as collagen, glycosaminoglycans, and proteoglycans. Through these combined actions it is studied for its influence on the local signaling environment associated with wound healing, matrix turnover, and angiogenesis.

- Clients building a longevity-oriented wellness plan
Important Considerations
GHK-Cu is offered strictly as educational information and within a physician-guided program; it is not a treatment, cure, or preventive for any disease. Because it delivers copper, candidacy, format, and protocol are highly individualized and determined one-on-one with Dr. Rob after review of your health history and goals. Individual experiences vary, and any use should be supervised by a qualified medical provider.
