Research peptides for sale in Europe and Ireland
Every product in this catalogue is a laboratory reagent: a sealed vial of lyophilized powder, its amount in milligrams, its purity, its storage conditions and, as soon as it exists, the analysis report of its lot. Look at those facts before the price. They say what is really in the vial, and that is where peptide shops differ most.
Search for "buy peptides" or "peptides Ireland" and two kinds of shop come up: skincare with a peptide in a cream or a serum, and suppliers of research peptides in vials. This catalogue is the second kind. We sell to researchers and laboratories only, and we give no information on amounts or use.
In stock now: size, price per mg and report
The table reads the stock and the prices of the cart: what you see here is what you pay at checkout. A size that is out of stock does not appear.

HPLC = purity measured in the Janoshik report of the lot; "pending" = analysis under way.
Choosing a vial size
Compare offers per milligram, never per vial. A larger vial is almost always cheaper per mg, because filling, sealing, labelling and testing a vial costs about the same whatever it holds. From 3 and from 5 vials of the same size, the price of each vial drops on its own in the cart, with no discount code. A small vial still makes sense for a first series: it avoids opening a large vial and keeping the rest. Lab supplies (bacteriostatic water, 1 mL syringes and alcohol pads) are in the grid above and travel in the same parcel. For retatrutide, the sizes, the reports and the delivery to Ireland are set out in the retatrutide buying guide.
What is in the catalogue
Each product page describes the substance itself: sequence, mass, salt form, storage and the report of the lot. In short:
- Retatrutide: a synthetic 39-amino-acid peptide carrying a fatty-acid chain, described in the literature as an agonist of three receptors; three sizes, each with its own Janoshik report.
- GHK-Cu: the copper tripeptide Gly-His-Lys, a blue-violet powder; the report also measures the copper content.
- AHK-Cu: the related copper tripeptide Ala-His-Lys, less described than GHK-Cu.
- BPC-157: a pentadecapeptide of 15 amino acids (GEPPPGKPADDAGLV), as the acetate salt.
- TB-500: the acetylated heptapeptide Ac-LKKTETQ, a fragment of thymosin beta-4; the mass on the report tells it apart from the full protein.
- Semax: the heptapeptide MEHFPGP, sensitive to methionine oxidation.
- Selank: a heptapeptide from the same Moscow institute as Semax.
- MOTS-c: a 16-amino-acid peptide encoded in mitochondrial DNA.
- KLOW: four lyophilized peptides together in one 80 mg vial (BPC-157, GHK-Cu, TB-500, KPV).
How we test: HPLC and Janoshik
Janoshik Analytical is an independent laboratory that tests peptides for suppliers and buyers. A report gives three things: purity by HPLC (how much of the powder is the peptide), identity by mass spectrometry (whether it is the right molecule) and the amount measured in the vial. Our specification is an HPLC purity of at least 99%; the value measured on each lot is in the table above and on the product page.
What a report does not cover: endotoxins, heavy metals and sterility are not measured in these analyses, and we do not claim them anywhere. All published reports, with a photo of the tested vial, are in the certificate of analysis library. How to check one yourself: Janoshik test report.
Delivery across Europe and Ireland
An order leaves our stock inside the European Union in a plain, sealed carton with no product name on the outside. From order to door, allow 4 to 6 working days, to Ireland as to the other served countries. The tracking link arrives by e-mail as soon as the carrier has the parcel.
Because the parcel stays inside the EU, there is no customs check and nothing to pay on arrival in Ireland, unlike a parcel sent from the United Kingdom or from outside Europe. Shipping is €9.90 and free from €120 of products, after the multi-vial discount. All countries and rates: shipping and delivery; for Irish labs, peptides in Ireland.
Payment and returns
You pay in euros by Visa, Mastercard, American Express, Apple Pay and Google Pay, with 3-D Secure. Card details are never stored on this site, no account is needed, and the checkout shows the final amount with shipping before you pay.
A sealed vial can be returned within 30 days of delivery for a full refund of the product price to the original payment method (refund policy). Who is behind OXpeptides and how to check it: is OXpeptides legit?
Research peptides and the law
None of the peptides in this catalogue holds a marketing authorisation as a medicine, in Ireland (HPRA) or from the European Medicines Agency. They are sold as laboratory reagents, for in vitro research, with "research use only" on the label. Offering or promoting a peptide as a product for people falls under medicines law. That is why this site gives no amounts, routes or promises.
Anti-doping rules: several peptides are on the WADA list, even when sold as research reagents. This is not legal advice; if in doubt about your own situation, ask a lawyer.
Frequently asked questions
Do you ship research peptides to Ireland?
Yes. Ireland is served from our stock inside the European Union, with tracking, in 4 to 6 working days. Prices are in euros, shipping is €9.90 and free from €120 of products, and there is no customs duty or import VAT on arrival.
Where can I buy research peptides in Europe?
From a supplier of research reagents that publishes an independent laboratory report per lot, ships from inside the EU with tracking and has a written return policy. OXpeptides ships from the EU to the countries listed on the shipping page, with a Janoshik report per size as soon as it is available.
Which peptides have a Janoshik report?
At the moment GHK-Cu and Retatrutide, each with a task number and a key that open the report on Janoshik's own site. On the other products the page says "analysis pending" until the report arrives; we never publish the numbers of another lot.
Which vial size should I choose?
The one that matches the amount your work needs. A larger vial is almost always cheaper per milligram, and from 3 and from 5 vials of the same size the price of each vial drops on its own in the cart, with no code. A small vial avoids opening more powder than you will use.
