Why this one
Reconstitute it and the solution turns blue — that is the copper, and it is the whole point. GHK's affinity for copper(II) is what the literature investigates: a tripeptide that both delivers the metal and modulates extracellular matrix gene expression.
Concentrated in fibroblast culture, collagen and matrix metalloproteinase assays, and preclinical skin research.
Where it shows up in the literature
Extracellular matrixCollagen, elastin and glycosaminoglycan expression in fibroblast culture.
Copper transportPeptide-mediated copper binding and delivery in cell models.
Dermal researchPreclinical skin remodelling and wound endpoints.
Antioxidant enzymologyInteraction with copper-dependent enzyme systems.

Handling
Store sealed vials at 2–8°C for short-term use, or at −20°C for long-term storage, and protect from light. Reconstitute with the diluent your protocol specifies; bacteriostatic water is the common choice where a vial will be entered more than once.
Allow refrigerated material to reach room temperature before opening, and avoid repeated freeze-thaw cycles once in solution.
Certificate of analysis
Every lot is tested by an independent ISO-accredited laboratory. The lot number on your vial resolves at the testing laboratory directly, so the purity figure never has to come from the party selling it to you.
