What is GHK-Cu (copper peptide)?

GHK-Cu is the copper complex of the tripeptide glycyl-L-histidyl-L-lysine, one of the most studied copper peptides in matrix and repair research. This guide covers what it is, how it is supplied, and what to verify before buying it in the Philippines.

The short answer

GHK is a naturally occurring tripeptide found in human plasma, with the sequence glycyl-L-histidyl-L-lysine. It binds copper(II) with high affinity, and the resulting complex — GHK-Cu — is what research works with. The copper is part of the molecule, not an additive.

ComplexGHK bound to copper(II)
AppearanceBlue powder; blue solution once reconstituted
Research areasExtracellular matrix, tissue repair, ageing models

GHK-Cu is supplied for laboratory research use only. Nothing here is a cosmetic, therapeutic, or medical claim.

Why the solution is blue

The blue colour comes from the bound copper(II) ion and is the expected appearance of a correctly reconstituted vial. A clear, evenly blue solution is normal. Cloudiness, floating particulates, or a colour shift toward green or brown is not, and indicates degradation or contamination.

What to verify before buying

  1. 1An independent certificate of analysis with a stated purity figure and a matching lot reference.
  2. 2Correct labelling: GHK-Cu, total milligrams, and lot number on the vial itself.

Frequently asked questions

What is GHK-Cu?

GHK-Cu is the copper(II) complex of the naturally occurring tripeptide glycyl-L-histidyl-L-lysine. It is studied in extracellular matrix, repair, and ageing research models.

Why is GHK-Cu blue?

The colour comes from the bound copper(II) ion, which is part of the molecule. A clear blue solution is expected once reconstituted.

How much is GHK-Cu in the Philippines?

The Origen 50mg vial is ₱1,499 and includes 3mL bacteriostatic water. Shipping is ₱350 nationwide via J&T Express, ₱400 for Metro Manila same-day, and free above ₱6,000.

Is GHK-Cu the same as the copper peptide in skincare?

Topical cosmetic products use the same molecule at low concentrations in a formulated base. Origen supplies GHK-Cu as a raw research material only, with no cosmetic or therapeutic use intended.
