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 senescence-pathway research 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 senescence research peptide 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 senescence research peptide stack.
