Notino peptide serums vs research GHK-Cu peptides
Notino carries cosmetic peptide serums, mostly from The Ordinary, such as the Multi-Peptide + Copper Peptides 1% Serum that you smooth onto your skin. Research peptides like GHK-Cu are a different thing: lyophilised compounds sold in sealed vials for in-vitro laboratory research only, with a stated purity target of 99% or higher checked by HPLC and mass spectrometry. Most PureChems products (41 of 54) show a certificate of analysis on the product page. They share a molecule name, GHK-Cu, but one is a finished skincare product and the other is a lab material. This guide explains what each one is and where they do and do not overlap.
| Peptide serums (The Ordinary at Notino) | PureChems research peptides | |
|---|---|---|
| What it is | A finished cosmetic face serum you apply to the skin. | A lyophilised research compound, a freeze-dried peptide powder, for in-vitro lab work. |
| Form | Liquid serum in a dropper bottle, 30 ml, ready to use. | Sealed glass vial of dried powder, reconstituted in the lab. |
| Typical contents | A blend of cosmetic peptides. The Multi-Peptide + Copper Peptides 1% Serum lists GHK-Cu (copper tripeptide-1), SYN-AKE, Matrixyl synthe'6, Matrixyl 3000, ARGIRELOX and hyaluronic acid. | One named peptide per vial, for example GHK-Cu or KPV, or a GHK-Cu, TB-500 and BPC-157 blend in our GLOW vial. |
| Sold as | A skincare product for personal use. | A research chemical, for in-vitro laboratory research only, not for human or animal use, 18+. |
| Testing shown | Cosmetic INCI ingredient list on the product page. | Purity target of at least 99% by HPLC and mass spectrometry. Most products (41 of 54) show a certificate of analysis on the product page. |
| Price example (checked 5 November 2026) | Multi-Peptide + Copper Peptides 1% Serum, 30 ml, EUR 35.30 (The Ordinary's own listed EU price; Notino's price not checked). | GHK-Cu 100 mg vial EUR 49.99; KPV 10 mg EUR 29.99. |
What Notino actually sells under "peptide serum"
Notino is a beauty retailer. When people search "notino peptide serum" or "notino copper peptides", the products behind that are cosmetic face serums, mostly from The Ordinary. Notino blocked our price check, so we do not quote a Notino price here. The Ordinary's own listed EU prices (checked November 2026) are EUR 35.30 for the Multi-Peptide + Copper Peptides 1% Serum (30 ml) and EUR 21.00 for the Multi-Peptide + HA Serum (30 ml). These are finished skincare: a liquid in a dropper bottle you smooth onto your face.
What a research peptide like GHK-Cu is
GHK-Cu (copper tripeptide-1) also sits inside those serums, at cosmetic strength, blended with other ingredients. As a research peptide it is sold on its own: a lyophilised (freeze-dried) powder in a sealed glass vial, reconstituted in a lab. It is studied in skin and tissue-repair research. We sell it strictly for in-vitro laboratory research, not for human or animal use. The same goes for the other compounds we carry, such as KPV and the GHK-Cu, TB-500 and BPC-157 blend in our GLOW vial.
Where the two overlap, and where they do not
The overlap is the molecule name. The Ordinary's copper serum contains GHK-Cu, and so does our research vial. After that they split. The serum is a cosmetic blend at low concentration, formulated and preserved for use on skin. Our vial is a single compound, freeze-dried, with a measured purity. One is a skincare product, the other is a lab material. They are not interchangeable, and a research peptide is not a serum you apply.
If you want the research compound, what to check
If you are buying the research compound rather than a cosmetic serum, three things matter.
- The purity. GHK-Cu states a purity target of 99% or higher, checked by HPLC and mass spectrometry. Certificates of analysis are shown on the product page for most products (41 of 54).
- How it is made. Our process page covers solid-phase synthesis, HPLC purification, identity by mass spectrometry, lyophilisation and sterile filling.
- Bacteriostatic water to reconstitute the powder, which we sell separately.

Frequently asked questions
Does Notino sell BPC-157 or research peptides?
No. Notino is a beauty retailer, and its "peptide" products are cosmetic serums like The Ordinary's Multi-Peptide range. Research peptides such as BPC-157 or standalone GHK-Cu are sold by research suppliers, not beauty stores.
Is The Ordinary's copper peptide serum the same as research GHK-Cu?
They share one ingredient, GHK-Cu (copper tripeptide-1). The serum is a cosmetic blend for the skin; research GHK-Cu is a single freeze-dried compound for lab use. They are not the same product.
Can I use a research peptide the way I would a serum from Notino?
No. Research peptides are sold for in-vitro laboratory research only, not for human or animal use. We do not give usage, dosing or application advice.
What is GHK-Cu?
GHK-Cu, or copper tripeptide-1, is a small copper-binding peptide studied in skin and tissue-repair research. In cosmetics it appears at low strength inside blended serums; as a research compound it is sold on its own in a vial.
What does a certificate of analysis show?
A COA reports the identity and purity of a specific batch, usually by HPLC and mass spectrometry. We show the certificate on the product page for most products (41 of 54); GHK-Cu states a purity target of at least 99% by HPLC and mass spectrometry.
I am in Czechia or Slovakia. Can I order research GHK-Cu?
Yes. We ship tracked across the European Union, including Czechia and Slovakia, with prices shown in local currency in non-euro countries and paid in euro. Delivery is usually 3 to 10 business days.
