GHK-Cu: A Complete Research Guide
GHK-Cu is a copper tripeptide originating from human plasma, studied for extracellular matrix and dermal remodelling research. Here is the full guide.
What is GHK-Cu?
GHK-Cu is a naturally occurring copper-binding tripeptide (glycyl-histidyl-lysine) originally identified in human plasma. Its concentration declines with age, which is part of why it has attracted such consistent research interest in dermal and longevity contexts.
Mechanism of action
GHK-Cu has been observed to influence collagen synthesis, glycosaminoglycan production and extracellular matrix signalling. The copper-bound form (GHK-Cu) is the form most studied in research, distinct from the free tripeptide GHK.
Pairing with MOTS-C and NAD
GHK-Cu sits within the broader longevity peptide research stack alongside MOTS-C (mitochondrial-derived peptide) and NAD precursor research compounds. Together they cover dermal, mitochondrial and cellular energetics pathways.
Storage
GHK-Cu is light-sensitive. Store lyophilised at minus 20 degrees Celsius and shield from direct UV. After reconstitution with bacteriostatic water, refrigerate at 2 to 8 degrees Celsius and use within 28 days.
Pair every reconstitution with sterile bacteriostatic water for laboratory-grade results.

Frequently Asked Questions
What is the difference between GHK and GHK-Cu?+
GHK is the base tripeptide. GHK-Cu is the copper-bound complex, which is the form most studied in research.
Is GHK-Cu light-sensitive?+
Yes. Store away from direct UV and in opaque or shielded containers where possible.
What purity is Pondok GHK-Cu?+
98 percent or higher with batch-specific COA available on the product page.
Can GHK-Cu be paired with MOTS-C?+
Yes, both are commonly studied within the same longevity peptide research stack.
