GHK-Cu
Copper peptide with regenerative properties. Improves skin, hair, and wound healing.
What GHK-Cu is
GHK-Cu, a naturally occurring copper complex of the tripeptide glycyl-L-histidyl-L-lysine, functions through various biological pathways to support tissue regeneration and repair. It is known to modulate the expression of numerous genes involved in wound healing, antioxidant defenses, and anti-inflammatory processes, rather than targeting a single receptor. The peptide facilitates the delivery of copper ions into cells, which are essential cofactors for enzymes like lysyl oxidase, crucial for collagen and elastin synthesis. It also acts as an antioxidant by scavenging free radicals and an anti-inflammatory agent by inhibiting the release of pro-inflammatory cytokines, contributing to its broad regenerative profile. While a precise half-life for research peptides can vary and is not extensively documented in all contexts, its effects are generally considered cumulative with consistent application.
For practical research purposes, GHK-Cu is often applied topically or studied for its systemic effects, with observable improvements in skin texture, elasticity, and overall appearance potentially noted within several weeks to a few months of consistent use. Benefits related to hair quality and density may follow a similar timeline. It is frequently explored in conjunction with other dermally active compounds such as hyaluronic acid or vitamin C to investigate potential synergistic effects. Research cycles can vary, though a typical investigative period often spans 2-3 months to allow for a comprehensive observation of potential outcomes. Researchers should note its characteristic blue color in solutions and consider individual tolerance, though GHK-Cu is generally considered well-tolerated. This peptide is intended for research purposes only and is not approved for medical use or as medical advice.

What people track
Because individual responses vary so much, the useful thing is your own record: what you logged and when, how much is left in the vial, and how your chosen metrics move over the weeks. Peptide Wizard keeps all of that in one place, alongside a 3D reference vial for GHK-Cu.
