How to Reconstitute GHK-Cu: A Step-by-Step Guide
Reconstituting GHK-Cu is not identical to reconstituting any other compound in this library. Freely water-soluble, and unmistakable: GHK-Cu solutions are a distinct blue.
In plain English
Never use an acidic liquid. Neutral or slightly alkaline only. A properly mixed vial gives a clear, evenly blue solution — that blue is the copper still correctly attached, which makes it a genuine visual quality check. A 100 mg vial in 5 mL gives 20 mg/mL.
What GHK-Cu actually is
GHK-Cu is three amino acids holding onto a copper atom — and the copper is part of the molecule, not an additive. It was identified in human blood in 1973, and researchers noticed its levels fall considerably with age. It is the only compound here whose condition you can partly judge by looking at it.

Diluent selection for GHK-Cu
Freely water-soluble, and unmistakable: GHK-Cu solutions are a distinct blue. That colour is the copper(II) coordination itself, which makes this the one compound here whose integrity you can partly assess by eye. A properly reconstituted vial gives a clear, evenly blue solution.
Common reconstitution reference
A 100 mg vial in 5 mL gives 20 mg/mL. The solution should be a clear, even blue — use neutral or slightly alkaline diluent only.
Open the GHK-Cu calculatorMethod notes for this compound
- Never reconstitute in acidic diluent — low pH dissociates the copper complex.
- Keep chelating agents such as EDTA out of any buffer used with this compound.
- Treat colour change as a discard signal: clear blue is correct, pale or green is not.
- Avoid contact with reducing agents, which will reduce Cu(II) to Cu(I) and collapse the complex.
What GHK-Cu is studied for
The best-populated area of the GHK-Cu literature, examined in dermal fibroblast models.
Studied for effects on the MMP/TIMP balance governing matrix turnover.
Copper itself is an angiogenic cofactor, and the complex is studied in that context.
Plasma GHK falls substantially between early and later adulthood, a finding central to research interest in the molecule.
