Research peptides in Belgium: euro prices, delivery and lab reports

Belgium searches for peptides in three languages.

In Flanders the query is « peptiden kopen », in Wallonia and Brussels it is « acheter des peptides », and the German-speaking East Cantons type « Peptide kaufen ».

Research groups in Ghent, Leuven, Liège or Brussels mostly work and order in English, so this page is written in English for them and for international labs with a Belgian address.

Two retatrutide guides cover the same ground in the local languages: retatrutide in België in Dutch, and acheter du retatrutide en Belgique in French. Prices, delivery times and lab reports are the same on all three.

The first page of results is thin. A Belgian shop sells research vials from short product pages.

A reseller with a pharmaceutical-sounding name lists dozens of compounds with one or two lines each. A skincare brand ranks with « peptide » serums that have nothing to do with a research vial.

Hardly any of them shows a lab report for the size you put in the basket.

The question a researcher in Antwerp or Namur actually asks is simpler: which supplier ships a sealed, tested vial to Belgium, in euros, without a customs letter a week later.

This page answers it, with our catalogue as the worked example and five checks that apply to any other shop.

Belgium sits next to three EU countries, and a parcel from any of them crosses no customs border.

A parcel from outside the EU is an import, whatever its value: Belgian VAT at 21 % is due from the first euro, customs duty can apply above €150, and the carrier charges a handling fee before it delivers.

Vials posted from the United Kingdom, the United States, China or Switzerland all fall into that category, and parcels holding a product presented for people can be held by customs.

Ours leave a warehouse in the European Union, in a plain sealed box with a tracking number, and are handed to the national post for the last mile:

You pay in euros by card with 3-D Secure, and no account is needed. A confirmation e-mail arrives at once; the tracking link follows when the parcel leaves. Every country we deliver to is on the shipping page.

Retatrutide (LY3437943) is an investigational peptide developed by Eli Lilly. In laboratory models it acts on three receptors at once: GLP-1, GIP and glucagon.

It is in phase 3 studies and holds no EU marketing authorisation, so no Belgian pharmacy can dispense it and the FAMHP lists no retatrutide medicine. What circulates in Belgium is lyophilised powder sold as a research reagent.

For that powder, the useful document is a lab report tied to the size you buy. Ours come from Janoshik Analytical:

The 30 mg vial brings the milligram down to €6.50/mg, against €8.99/mg in the 10 mg.

The purchase guide with sizes and storage is buy retatrutide in Europe; the vials are on the retatrutide 10, 20 and 30 mg page. We publish nothing about use in people; a shop that does is selling an unauthorised medicinal product.

In Belgium, « peptides » on a shop shelf usually means a cream.

Cosmetic serums carry a fraction of a percent of a copper peptide in a base of water, oils and preservatives, priced per millilitre. A research vial is the peptide alone, as a lyophilised powder, priced per milligram.

The two are not substitutes and should not be compared on price.

The GHK-Cu 100 mg lot on sale has its own Janoshik report, task 217016, at 99.603 % purity.

GHK-Cu is glycyl-L-histidyl-L-lysine bound to a copper ion, a blue powder in the vial; AHK-Cu swaps the first amino acid for alanine. GHK-Cu vs AHK-Cu sets out the differences.

Labs that work with several peptides at once also look at KLOW 80 mg (€139.90), which combines BPC-157, GHK-Cu, TB-500 and KPV in one vial.

After retatrutide, the two names Belgian buyers type most are BPC-157 and TB-500.

BPC-157 is a 15-amino-acid sequence taken from a protein of gastric juice and studied in cell and animal models; TB-500 is a synthetic fragment of thymosin beta-4.

Neither has gone through a full clinical programme, neither is an authorised medicine in Belgium, and both are therefore sold as reagents only.

Each ships as a sealed 10 mg vial: BPC-157 and TB-500, with prices in the table at the top of this page. Labs that study the pair side by side will find the background in BPC-157 and TB-500, and the buying details in buy BPC-157.

The sticker price of a vial misleads as soon as sizes differ. A 5 mg vial at a low price can cost more per milligram than a 20 mg vial at twice the price. Divide by the milligrams on the label and compare vials of the same size.

The second step is to ask whether the label is true. A « 10 mg » vial that holds 7 mg costs 43 % more per real milligram than it claims.

Only a report with the measured content of the size on sale settles that, so a fair comparison is limited to shops that publish one.

Then add what the price leaves out: a parcel from outside the EU carries 21 % VAT and a carrier fee, which no product page shows.

In our basket, the price per vial drops on its own from 3 and from 5 vials of the same size, without a code.

1. A lab report per size. A single PDF for the smallest vial, reused across the range, says nothing about the vial you receive.
2. A report that verifies. Janoshik reports carry a task number and a key; typed on janoshik.com, they must open the same document as the shop's.
3. A measured quantity next to the purity. « 99 % pure » on 7 mg of a « 10 mg » vial is still 7 mg.
4. Dispatch from the EU. Prices in pounds or dollars usually mean VAT and a fee at the door.
5. A named company with a written return policy and card payment. Crypto-only checkout or a transfer to a private account is a warning sign.

Instructions for people, testimonials or promised outcomes on a product page mean the shop is selling a medicinal product without authorisation.

The full method is in how to check a peptide supplier, and every heading of a report is explained in Janoshik test report.

Sealed lyophilised vials keep best at −20 °C, in their box, away from light and moisture. On arrival the seal should be intact and the powder dry.

Details are in lyophilized peptides storage. Bacteriostatic water, a laboratory diluent with 0.9 % benzyl alcohol, travels in the same parcel and adds nothing to the shipping cost.

Belgium's medicines regulator is the Federal Agency for Medicines and Health Products: FAMHP in English, AFMPS in French, FAGG in Dutch.

It authorises medicines, supervises their distribution and acts against unauthorised medicines sold online, together with Belgian customs.

A product presented as something to give to people, with an amount to take or a promised effect, is a medicine and needs an authorisation.

Research peptides have none, which is why they can only be offered as laboratory reagents: labelled « for research use only », described by their chemistry, with no instructions for people or animals.

How a product is presented draws the line, not its name; a reagent sold and labelled as such by an EU seller is a different case from a medicine offered to the public.

Researchers who compete should know that the World Anti-Doping Agency lists BPC-157 (class S0) and TB-500 (class S2) as prohibited. This page is not legal advice; each institution's own rules apply to its lab.

For laboratory research only. Not for human or veterinary use.
