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.
Open the dosage calculatorThe 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.
| Attribute | Detail |
|---|---|
| Sequence | Gly-His-Lys (GHK) |
| Complex | GHK bound to copper(II) |
| Appearance | Blue powder; blue solution once reconstituted |
| Research areas | Extracellular 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
- 1An independent certificate of analysis with a stated purity figure and a matching lot reference.
- 2Correct labelling: GHK-Cu, total milligrams, and lot number on the vial itself.
- 3Blue powder in an intact, sealed vial with an undisturbed stopper.
- 4A domestic seller, so the vial is not sitting in customs for weeks at ambient temperature.

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.
Every vial ships with its own published certificate.
Purity, quantity, and endotoxin tested by Janoshik Analytical, published before the product goes on sale.

How to mix GHK-Cu
A 50mg GHK-Cu vial is reconstituted like any lyophilized peptide, with one difference: the finished solution should be clear blue. This guide gives the water volumes, the concentrations they produce, and how to store the vial afterwards.
GHK-Cu in the Philippines
GHK-Cu is a naturally occurring copper tripeptide complex studied in skin, matrix, and repair research. This guide covers what it is, how the 50mg vial is supplied in the Philippines, how to reconstitute and store it, and what to verify before buying.
Peptide storage guide
Storage rules split cleanly in two: the dry vial is forgiving, the reconstituted vial is not. Philippine heat and power interruptions make the second half worth planning for.
