Why does the vial look empty?
That’s normal. The peptide is supplied lyophilised (freeze-dried) — often a thin film or a few milligrams at the base of the vial, easy to mistake for empty. It’s all there; reconstitute with bacteriostatic water before use.
Research handling note
Reconstitute with bacteriostatic water and store the lyophilised vial at −20 °C until use; once reconstituted, refrigerate and use within the documented window.

GHK-Cu — research profile

For research purposes only — not for human consumption

GHK-Cu is the copper(II) complex of the tripeptide glycyl-L-histidyl-L-lysine, a sequence found naturally in human plasma whose concentration is reported to decline with age. It is one of the most-studied peptides in skin and tissue-remodelling research.

Research attributes much of its activity to copper delivery and to modulation of genes governing extracellular-matrix turnover, with reported effects on collagen, elastin and antioxidant systems in cell and tissue models.

How it’s studied

  • Matrix remodelling: collagen and elastin synthesis in dermal models.
  • Copper transport: delivery of Cu(II) for enzyme-cofactor pathways.
  • Antioxidant signalling: modulation of oxidative-stress responses.
  • Gene expression: broad shifts reported across skin-remodelling gene panels.

Verifiability

Batch Testing & COA

Every production batch is sent for independent, third-party analysis at Janoshik Analytical. When results return, the full Certificate of Analysis for the exact batch you receive is published here and in our COA library, carrying its SHA-256 checksum and the lot number printed on your vial, so you can confirm the document is genuine and untampered. We publish every certificate, including any that fail.
