GHK-Cu
Also known as Copper tripeptide-1
Naturally occurring copper-binding tripeptide studied in skin, hair, and tissue-remodelling research.
- Classification
- Copper-complexed tripeptide (Gly-His-Lys)
- Supplied form
- Lyophilized blue powder, research vial
- Storage
- Lyophilized powder is typically stored refrigerated or frozen and protected from light. Once reconstituted, solutions are generally kept refrigerated and handled under standard laboratory practice.
- Solubility
- Readily soluble in water; solutions display the characteristic blue copper complex colour.
What GHK-Cu is
GHK-Cu is a tripeptide that binds copper(II) with high affinity and occurs naturally in human plasma, where its concentration declines with age. The copper complex is the form most often studied.
Research context
Literature covers collagen and extracellular matrix signalling, antioxidant activity, wound-model studies, and cosmetic-science investigations of skin and hair follicle biology.
Handling in the laboratory
Supplied as a 100mg vial. Protect from prolonged light exposure; copper peptide solutions are typically prepared fresh for experimental work.
Concentration reference
Working concentration is determined solely by the solvent volume added to the vial. The Lucent Life reconstitution calculator converts vial strength and solvent volume into mg/mL and U-100 syringe units. It performs unit math only and does not recommend any dosing, administration, or frequency.

Frequently asked
Why is the powder blue?
The colour comes from the bound copper(II) ion in the peptide-copper complex.
