GHK-Cu is the copper(II) complex of the tripeptide glycyl-L-histidyl-L-lysine, supplied as a lyophilised powder at 50 mg per vial.
Supplied as a lyophilised powder in a crimp-sealed glass vial. Store lyophilised at −20 °C, protected from light. Dispatched tracked from UK stock on working days, with UK delivery included in the price.
GHK-Cu is the copper(II) complex of the tripeptide glycyl-L-histidyl-L-lysine: three residues, sequence Gly-His-Lys, with one copper ion bound to the peptide. The same substance is also written GHK copper complex; the shorthand used across this site is simply copper peptide. The spec table gives CAS number 89030-95-5, which is the registry entry for the copper complex. The uncomplexed tripeptide GHK has its own CAS entry and is a different substance from the one listed here, so the two should not be treated as interchangeable in a catalogue search.
The 50 mg on the label is the fill weight per vial — the mass of lyophilised solid sealed into the glass — not the mass of copper complex it holds. A freeze-dried cake carries bound water, counter-ions and traces of residual salt, so net peptide content is always below the fill figure; the distinction is set out in our guide to peptide purity vs net peptide content. NorthScientific does not publish independent third-party analysis. We state what the material is — name, format, fill weight and, where established, sequence and identifier — and nothing beyond that.
The GHK-Cu 50 mg vial is £17.99, the total payable: UK delivery is included, Stripe takes payment, and nothing is added at checkout. From UK stock, an order confirmed before 14:00 on a working day leaves the same day where stock allows, by Royal Mail Tracked 24 in unbranded packaging, to the United Kingdom including Northern Ireland only. For multi-vial or invoiced laboratory orders, email info@northscientific.co.uk. See the shipping page; the 14-day consumer right to cancel ends once this vial's crimp seal is broken (terms). We supply research organisations, educational and commercial laboratories, and individuals purchasing for legitimate research.
GHK-Cu is supplied as lyophilised powder, 50 mg fill, in a crimp-sealed glass vial; storage is −20 °C, protected from light. Gly-His-Lys contains none of the methionine, cysteine or tryptophan residues that carry the oxidation discussion in our guide to lyophilised peptide storage; the stated conditions apply regardless, because backbone hydrolysis needs only water and a peptide bond. Why we supply a dry solid rather than a solution is covered in lyophilised vs non-lyophilised peptides.
GHK-Cu is supplied for laboratory research use only. It is not a licensed medicine and has not been evaluated or approved by the MHRA; it is not a food, cosmetic or supplement; and it is not for human or veterinary consumption. NorthScientific provides no dosing, protocol or outcome guidance of any kind, and nothing on this page should be read as such. By ordering you confirm the material will be used solely for legitimate research.
No. GHK-Cu is supplied for laboratory research only and is not for human or veterinary consumption; that applies to the copper complex on this page exactly as it does to every other material we hold. We give no dosing, protocol or outcome guidance of any kind.
No. GHK-Cu is not a licensed medicine and has not been evaluated or approved by the MHRA. NorthScientific supplies it solely as a research-use-only laboratory reagent to laboratories and individuals carrying out legitimate research; we do not supply it for human or veterinary use.
Yes. £17.99 is the whole cost of one 50 mg vial of GHK-Cu with UK delivery included, and a single vial can be ordered on its own. Held in UK stock, it leaves by Royal Mail Tracked 24 in unbranded packaging the same day when the order is confirmed before 14:00 on a working day, where stock allows.
No. 50 mg is the fill weight: the mass of freeze-dried solid sealed into the vial. The peptide fraction is lower, because the cake also carries bound water, counter-ions and residual salts, and we publish no third-party analysis that puts a figure on it.
This listing is the copper complex on its own, 50 mg per vial at £17.99. GLOW is a co-lyophilised blend of GHK-Cu 50 mg, BPC-157 10 mg and TB-500 10 mg in a single 70 mg vial, so choose this page where a study needs GHK-Cu without the other two peptides present, and GLOW where it needs all three in one solid.
