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.

Also known as: Copper tripeptide-1, Prezatide copper, GHK copper, Copper peptide GHK-Cu, Glycyl-L-histidyl-L-lysine copper complex
Structural class: copper(II) complex of the tripeptide glycyl-L-histidyl-L-lysine (Gly-His-Lys), 1:1 peptide:copper
Residues: 3 amino acids
Salt form: supplied as the copper(II) complex, usually as an acetate or trifluoroacetate salt of the complex
PubChem CID: 165429100
UNII: 6BJQ43T1I9

Questions

GHK-Cu 50mg — common questions

Is GHK-Cu 50mg the same compound as the larger GHK-Cu vials?

Yes. GHK-Cu 50mg, 80mg and 100mg are the same compound, GHK-Cu (CAS 89030-95-5), in the same lyophilized form. They are separate listings that differ only in the stated quantity per vial and the price per vial. The 50 mg vial is the smallest size Pepta Labs lists.

What comes in a GHK-Cu 50mg vial?

One sealed glass vial holding a supplier-stated 50 mg of GHK-Cu as dry lyophilized powder. The label names the compound, the quantity and the research-use designation; it carries no lot or batch number. The 50 mg is the stated quantity of dry powder; net peptide content is not reported per listing, and vial fill-quantity testing is not claimed.

Where can I buy GHK-Cu 50mg?

Pepta Labs lists GHK-Cu 50mg on this page for US addresses only, as one sealed vial of lyophilized powder sold for laboratory research only. The same compound is also listed as GHK-Cu 80mg and GHK-Cu 100mg. Orders are placed from a free account with a confirmed email.

How do I request the GHK-Cu 50mg HPLC report?

Request it on this page or email support@peptalabs.com with the compound name and size, and it is sent by email, before you order if you want it. It covers the sampled production run: purity by RP-HPLC as area-% and identity by mass spectrometry, from an independent lab. The Learn guide How to Read and Verify a Peptide Certificate of Analysis (COA) walks through each section.

Does GHK-Cu 50mg need cold shipping?

No. It ships as dry lyophilized powder at ambient temperature with no cold pack or insulated packaging. On arrival, keep the sealed vial at 2-8 C, or at -20 C for long-term storage, away from light and moisture.

What does GHK-Cu 50mg cost?

GHK-Cu 50mg starts at $36.99 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 50mg 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).
