Europe research peptide supplier report, September 2026

Key findings

1. 01

   96 stores sell to buyers in Europe. 22 are based in Europe and 74 ship in from abroad: 38 from the UK, 11 from the US and 25 that do not say where they are based.

2. 02

   32% of stores based in Europe say their products are third-party tested; none of those claims has been checked yet. 7 of the 22 stores based in Europe (32%) say on their own website that their products are third-party tested, and 16 link a page of certificates of analysis. PepFinder has not yet reviewed a certificate from any store serving Europe, and one store serving Europe has passed a PepFinder staff check. These are the stores' statements, not results we have confirmed; stores may hold certificates we have not seen.

3. 03

   Most listings sold to Europe are priced in other currencies. These stores list 4,402 products, but only 1,385 are priced in EUR; the other 3,017 are in other currencies and are left out, never converted. Of the 1,385 EUR listings, 921 (66%) state a price, form and quantity we can compare.

4. 04

   The same peptide sells at very different prices. Retatrutide is the most widely listed: the middle half of 52 single-vial listings from 12 stores runs from €5.14 to €11.40 per mg (median €9.17), and the most expensive is 3.6 times the median. A 10 mg vial, the size most often listed, has a median listed price of €92.00. Part of any per-mg spread is vial size, since larger vials usually cost less per mg.

Which prices can be compared

Every listing priced in EUR by a store serving Europe, by what we could read from it. Only the first row enters any price figure. 3,017 more listings from these stores are priced in other currencies and are not included.

Of the 921 compared prices, 773 are single vials and 148 are packs of several vials. The price figures below use single vials only, so a bulk price is never set against one vial.

How the figures are built

Stores serving the region

Published, active suppliers based in the market or stating they ship to it.

Based in the region

The supplier's recorded country is in the market.

Third-party testing

What the supplier's own website states. 'stated' is a claim, not a verified result; 'notFound' means we read the site and found no such statement; 'notAssessed' means not yet read.

Certificates page

The supplier's site links a page of certificates of analysis. Not a check of any certificate.

Certificates reviewed

Suppliers with at least one certificate PepFinder holds and has reviewed.

PepFinder check

Suppliers with a PepFinder staff verification check passed and not expired.

Compared price

Listed price in the market currency whose form, total mass and currency we could read with confidence, not held for review and not an outlier. Only VALID prices enter the distributions.

Single vial

One vial of powder of one peptide. Packs of several vials, pens, capsules, sprays, kits and blends are excluded from the distributions.

Minimum sample

A peptide is reported once it has at least 5 listings from 3 suppliers.

One business, several sites

A business trading through several confirmed storefronts is counted once per identical listing.

Prices are listed prices as each store's site showed them when last checked, without shipping or tax. Nothing here describes what the products do or how they are used; they are sold for laboratory research. How we collect and validate prices · Legal status in Europe.
