This page covers GHK-Cu, the material also catalogued as GHK copper peptide or copper tripeptide-1, and lists every pack of it we carry. You will find the price of each pack in euros, the price per milligram or per millilitre where the pack size allows that sum, the chemistry, notes on form and storage, and what a shipment to the United Kingdom or Ireland involves. It is all meant for laboratory and research use. GHK-Cu is not a medicine and not a dietary supplement, and we make no claim about what anyone would observe with it.
Price and packaging
Thirteen pack options contain GHK-Cu, across plain vials, pen cartridges, a nasal spray kit, two serums, two blend vials and three bundles.

Within the plain vials the arithmetic is simple. The 50 mg vial comes to € 0,80 per milligram and the 100 mg vial to € 0,60, so of those two the larger is the cheaper per milligram. A bigger pack is not always the cheaper one in our catalogue, so the division is worth doing pack by pack. The two blend vials hold several peptides in one vial, so no per-milligram figure is given for them: the price buys more than one substance. A bundle joins separate substances in one box, so no per-milligram figure for it would compare with anything either.
What GHK-Cu is
GHK is a tripeptide: glycine, histidine and lysine joined in that order and written Gly-His-Lys. The free peptide has the molecular formula C14H24N6O4 and an average molecular mass near 340.4 g/mol, small next to most chains in the catalogue. GHK-Cu is that tripeptide bound to a copper(II) ion in a one to one complex, and the metal is why the lyophilised cake and its solutions are deep blue rather than white.
The metal is also the main thing separating it from its neighbours, since the bare peptide and the copper complex are not interchangeable materials. Length is the other. Three residues is short: most chains catalogued alongside it run to dozens of residues and several thousand g/mol.
Where it sits in the catalogue
The closest neighbour is AHK-Cu, which swaps glycine for alanine at the first position and is likewise a copper-binding tripeptide. SNAP-8, an eight residue peptide with no metal in it, is a different proposition and shares one of the serums with GHK-Cu. The blends put GHK-Cu together with peptides from other groups: GLOW-70 adds BPC-157 and TB-500, and KLOW-80 adds KPV on top of those. That is a grouping by substance and format, not a statement about what any of them do. The single substance vial is GHK-Cu, the metered form is the GHK-Cu pen, and the wider range sits under buy peptides.
Form, handling and storage
A vial holds a lyophilised cake. Bacteriostatic water goes in slowly, down the inside wall of the vial rather than straight onto the cake, and the vial is then swirled until the cake has dissolved. Shaking is the wrong motion here. Once reconstituted, the vial belongs in the fridge and not the freezer. Sealed vials of powder keep cool, dry and dark.
The serums come as finished liquids in a 35 ml bottle: cap closed, away from sunlight and heat. A pen is a sealed cartridge, so nothing is mixed by hand. A nasal spray kit pairs the lyophilised material with a spray bottle it is transferred into once dissolved, and the product page states what the box contains.
Shipping and analysis
Everything ships from the Netherlands. Delivery to the United Kingdom is a flat € 15,95 and is free on orders from € 200. Delivery to Ireland is a flat € 14,95, also free from € 200. Prices on the site are quoted in euros.
The United Kingdom is not in the European Union, so a parcel to a British address is an import. Any import VAT or duty owed on it is charged by the carrier to the recipient, separately from what you pay us. Ireland is in the European Union, so a parcel to an Irish address is an intra-EU shipment and no import charge of that kind arises.
Every batch is analysed and a certificate of analysis is on file, kept in our analysis documentation.
Frequently asked questions
What may I use this for?
Laboratory and research purposes only. It is not for human or veterinary use, and we give no dosing advice, neither here nor on the product pages.
What is the difference between GHK and GHK-Cu?
GHK is the bare tripeptide Gly-His-Lys. GHK-Cu is that peptide as a complex with copper(II). Every pack on this page is the copper complex.
Which pack works out cheapest per milligram?
Of the plain vials, the 100 mg at € 0,60 per milligram against € 0,80 for the 50 mg. The blends and bundles hold more than one substance, so they cannot be set against those figures.
Do you deliver to the United Kingdom and Ireland?
Yes, from the Netherlands, at the flat rates given above. A UK parcel is an import, so the carrier may collect import VAT or duty from the recipient. For Ireland that does not arise.
Can I see the analysis for a batch?
Yes. Each batch is analysed and its certificate is on file, so the paperwork matches the vial in hand.
For laboratory and research use only. Not for human or veterinary use.
