In the literature
GHK‑Cu is the copper(II) complex of the tripeptide glycyl-L-histidyl-L-lysine (Gly-His-Lys), supplied as a lyophilized powder in a sealed borosilicate vial.
GHK‑Cu is one of the most published copper tripeptides in the literature. Genomic studies in cellular models describe modulation of the expression of several thousand genes.
Scientific data
GHK-Cu — identity, literature and limits
Sequence
Gly-His-Lys (GHK) · Cu(II)
| Systematic name | Glycyl-L-histidyl-L-lysine, copper(II) complex |
|---|---|
| Synonyms and research codes | GHK-Cu · copper tripeptide-1 · prezatide copper · GHK copper · Cu-GHK · [N2-(N-glycyl-L-histidyl)-L-lysinato(2-)]copper |
| Chain length | 3 residues (tripeptide), one copper(II) centre |
| Molecular formula | C14H24N6O4 (free GHK) · C14H23CuN6O4+ (copper complex) |
| Molar mass | 340.38 g/mol (free GHK) · 402.92 g/mol (copper complex) |
| CAS number | 89030-95-5 |
| PubChem CID | 71587328 |
| Origin of the sequence | The tripeptide occurs naturally and was isolated from blood serum in 1973. The material supplied is obtained by solid-phase peptide synthesis, then chelated with copper(II) — no biological extraction step. |
| Form and container | Lyophilized powder, blue to blue-violet, water-soluble, in a sealed borosilicate vial under an inert headspace. |
| Storage | −20 °C sealed, away from light, moisture and oxygen. 2 to 8 °C for four weeks or less. |
What has been studied
- The tripeptide was isolated from blood serum and described in the literature in 1973. [1]
- The geometry of its copper(II) coordination in solution was determined by spectroscopic measurement and published in 1982. [2]
- The GHK–copper(II) motif has since been used as a crystallization and phasing tag in macromolecular crystallography. [3]
What is not established
No controlled study in people has been published for this material, and none of the sources above establishes an outcome in a living organism.
Most of the published measurement comes from cell-free chemistry and from cell culture; nothing in that record transfers by itself to any other system.

Questions about GHK‑Cu
About OXpeptides
Who we are
OX RESEARCH LTD operates OXpeptides. Company number 17464288 (England and Wales). We supply lyophilized research peptides in sealed glass vials, and one laboratory diluent, to researchers and laboratories.
How we work
Our reports come from Janoshik Analytical, one per size: HPLC purity and mass-spectrometry identity. Each report is published on the product page with its date as soon as the laboratory returns it; a product whose report is not back says so, in those words, rather than borrowing figures from elsewhere. Every vial is crimp-sealed and carries the compound name and the net quantity in milligrams; each report is published with its task number and verification key. Orders ship from the warehouse that serves the delivery address, tracked.
Who we sell to
Researchers and laboratories. Three things we do not do: we publish no quantities, no routes and no schedules anywhere on this site, and support declines those questions; we publish no certificate we do not hold; and we publish no customer review that does not come from a verified order.
