GHK-Cu 50mg overview
GHK-Cu (Glycyl-L-histidyl-L-lysine copper(II) complex, CAS# 89030-95-5) is an endogenous tripeptide–copper(II) coordination complex naturally occurring in human plasma, urine, and saliva. NexPept supplies it as a lyophilized research reference standard for extracellular-matrix remodeling assays, fibroblast signalling studies, and copper-transport research. Not for use in any living organism.
Every lot is independently tested by a third-party analytical laboratory before it is listed. The Certificate of Analysis reports HPLC purity, mass spectrometry identity confirmation, and net-content verification, and stays published in our COA library after the batch sells out.
For background on the compound itself — the copper(II) coordination chemistry, where GHK occurs endogenously, and what the published research record covers — see our GHK-Cu research overview.

Research context
GHK-Cu is used as a peptide tool compound in preclinical in vitro settings. Published work has examined its behaviour in extracellular-matrix remodeling and collagen-related fibroblast signalling assays, copper-transport and copper-chaperone protein studies, gene-expression modulation research, and oxidative-stress pathway investigations.
As a defined tripeptide–copper(II) coordination complex with consistent structural characteristics between lots, it is used in controlled laboratory environments to study copper-dependent cell signalling and downstream matrix-related mechanisms. Lot-to-lot consistency matters for this kind of work, which is why every NexPept batch is published with its own purity figure rather than a blanket claim.
This compound has not been authorized by Health Canada for any therapeutic, clinical, or human use.

Frequently asked questions
What testing does each batch go through?
Identity and purity are confirmed by high-performance liquid chromatography and mass spectrometry before a lot is listed. The current lot, NP-GHK-001, tested at 99.12% on April 16, 2026. If a lot has not been tested, it does not go on sale.
What class of compound is GHK-Cu?
An endogenous copper(II)-tripeptide coordination complex — the tripeptide glycyl-L-histidyl-L-lysine chelated to a copper ion. It is supplied as a lyophilized powder and handled as a peptide reference standard, not as a formulation.
How does the 50mg vial differ from the 100mg vial?
Both vials contain the same GHK-Cu compound; the 50mg format simply carries half the net quantity of the 100mg vial. Researchers choose the size that best matches their planned assay volume and dilution series.
What physical form does it arrive in?
A blue lyophilized (freeze-dried) solid, sealed in a single vial — the characteristic colour of the copper coordination complex. Net quantity is 50mg. No preparation, reconstitution or handling instructions are supplied; those are determined by qualified personnel under your own institutional protocols.
