Chemical identity

What GHK-Cu is

GHK-Cu, also named copper tripeptide-1 (INCI) or prezatide copper, is the copper(II) complex of the tripeptide glycyl-L-histidyl-L-lysine (Gly-His-Lys, GHK). The 1:1 complex has the molecular formula C14H22CuN6O4 and a molecular weight of 401.91 g/mol (PubChem CID 165429100), the values shown on the Pepta Labs listing; the copper-free tripeptide GHK is C14H24N6O4, 340.38 g/mol (CID 73587), and PubChem also records a 2:1 peptide:copper complex (C28H48CuN12O8, 744.3 g/mol, CID 133697840). CAS 89030-95-5 and UNII 6BJQ43T1I9 are assigned to the prezatide copper entry. In the complex the copper ion is chelated by the glycine amino nitrogen, the deprotonated peptide amide nitrogen and the histidine imidazole nitrogen, which gives the solid its characteristic blue to blue-violet colour. Pepta Labs supplies GHK-Cu as a lyophilized powder in sealed glass vials (50 mg, 80 mg and 100 mg quantities) with reported RP-HPLC purity and mass-spectrometric identity. Store at 2-8 C on arrival or at -20 C for long-term storage, protected from light and moisture. Laboratory research use only.

Questions

GHK-Cu 80mg — common questions

How does GHK-Cu 80mg differ from the 50mg and 100mg listings?

Only in the stated quantity of powder per vial and the price. All three listings are the same compound, GHK-Cu (CAS 89030-95-5), in the same lyophilized form with the same storage conditions and the same report process. The 80 mg vial sits between the 50 mg and 100 mg sizes.

What is in a GHK-Cu 80mg vial?

A supplier-stated 80 mg of GHK-Cu as dry lyophilized powder, blue to blue-violet in colour, in a sealed glass vial labelled with the compound, quantity and research-use designation. Vial labels carry no lot or batch number, and vial fill-quantity testing is not claimed.

What salt form is GHK-Cu supplied in?

GHK-Cu is supplied as the copper(II) complex, usually as an acetate or trifluoroacetate salt of the complex. The 80 mg on the label is the stated quantity of powder, and net peptide content is not reported per listing. The Learn guide How Net Peptide Content Is Determined explains the difference between powder weight and peptide content.

Can I get the GHK-Cu 80mg analytical report before I order?

Yes. Request it on this page or email support@peptalabs.com with the compound name and size, and it is sent by email. It shows an independent lab's RP-HPLC purity (area-%) and mass-spectrometry identity for the sampled production run Pepta Labs sourced; it is not specific to one vial. Sterility, endotoxin or LAL, potency, pharmaceutical-grade, cGMP, contaminant-panel and vial fill-quantity testing are not claimed.

How do I store GHK-Cu 80mg before opening?

Keep the sealed vial at 2-8 C after it arrives, or at -20 C for long-term storage, protected from light and moisture. As a dry powder it ships at ambient temperature without a cold pack. The Learn guide Storage Temperature and Handling of Lyophilized Research Peptides covers dry-powder storage in more detail.

What does GHK-Cu 80mg cost?

GHK-Cu 80mg starts at $46.23 per vial. 3-vial packs are 7% off and 5-vial packs are 14% off. US shipping is free with no minimum.

What payment methods are accepted?

Pepta Labs accepts Cash App, Venmo, Zelle, Bitcoin and Ethereum (5% crypto discount). Payment instructions are emailed as soon as you place your order.

Is this for human or animal use?

No. GHK-Cu 80mg is offered solely for laboratory research and is not for human or animal use, consumption, administration, diagnosis or treatment. Buyers certify this at checkout.

What is the difference between GHK and GHK-Cu?

GHK is the free tripeptide glycyl-L-histidyl-L-lysine (C14H24N6O4, 340.38 g/mol). GHK-Cu is the same tripeptide coordinated to one copper(II) ion (C14H22CuN6O4, 401.91 g/mol, CAS 89030-95-5); the two hydrogens lost on chelation account for the formula difference. GHK-Cu is a blue-violet solid, whereas GHK is white.

Which CAS number and PubChem record apply to GHK-Cu?

CAS 89030-95-5 and UNII 6BJQ43T1I9 are registered under prezatide copper / copper tripeptide-1. PubChem lists several related records: CID 165429100 for the neutral 1:1 complex (401.91 g/mol, the formula on the Pepta Labs listing), CID 71587328 for the cationic form (402.92) and CID 133697840 for the 2:1 peptide:copper complex (744.3).

Is the copper part of the listed molecular weight?

Yes. The listed formula C14H22CuN6O4 (401.91 g/mol) includes one copper atom (63.55 g/mol).
