Key findings
- 01
404 stores sell to buyers in the UK. 358 are based in the UK and 46 ship in from abroad: 1 from Australia, 2 from Canada, 1 from Switzerland, 35 from elsewhere and 7 that do not say where they are based.
- 02
64% of stores based in the UK say their products are third-party tested; few of those claims have been checked yet. 230 of the 358 stores based in the UK (64%) say on their own website that their products are third-party tested, and 186 link a page of certificates of analysis. PepFinder has reviewed certificates from 17 stores serving the UK, and two stores serving the UK have passed a PepFinder staff check. These are the stores' statements, not results we have confirmed; stores may hold certificates we have not seen.
- 03
67 in 100 listed prices can be compared like for like. Of 13,741 listings priced in GBP by stores serving the UK, 9,245 (67%) state a price, form and quantity we can read with confidence. The rest are held back from every figure here: other forms such as pens and kits, listings with no quantity or no price, and prices that failed our checks.
- 04
The same peptide sells at very different prices. Retatrutide is the most widely listed: the middle half of 421 single-vial listings from 119 stores runs from £3.25 to £6.25 per mg (median £4.45), and the most expensive is 5.4 times the median. A 20 mg vial, the size most often listed, has a median listed price of £99.00. Part of any per-mg spread is vial size, since larger vials usually cost less per mg.
- 05
Since September 2026. 156 more stores serve the UK than in September 2026 (404 now), and the median listed price per mg for Retatrutide, the most listed peptide priced in both months, moved from £4.50 to £4.45 (-1.1%). Month-on-month figures compare this region with itself, in GBP.
Since September 2026
This region against its own September 2026 report. Prices are in GBP in both months; a peptide appears only if it had enough prices both times.

Who sells to buyers in the UK
Testing and certificate figures count what each store's own site says. For the other stores we found no such statement or have not yet read that part of the site, so this does not say how many do not test. A certificate counts as reviewed only once PepFinder holds it and has checked it.
| Stores | Count | State third-party testing | Link a certificates page | Certificates reviewed by PepFinder | Passed a PepFinder check |
|---|---|---|---|---|---|
| Based in the UK | 358 | 230 (64%) | 186 (52%) | 11 | 2 |
| Ship to the UK from abroad | 46 | 36 (78%) | 36 (78%) | 6 | 0 |
Which prices can be compared
Every listing priced in GBP by a store serving the UK, by what we could read from it. Only the first row enters any price figure. 4,538 more listings from these stores are priced in other currencies and are not included.
| Listing | Count | Share |
|---|---|---|
| Compared: price, form and quantity read with confidence | 9,245 | 67% |
| Another form (pen, capsules, spray, kit, blend) or excluded by an editor | 2,175 | 16% |
| No quantity stated | 1,463 | 11% |
| No price shown | 250 | 2% |
| Price shown as zero | 239 | 2% |
| Failed a price check | 198 | 1% |
| Far outside the market for that peptide | 149 | 1% |
| Held for review (unclear size or a sharp price change) | 22 | 0% |
Of the 9,245 compared prices, 8,213 are single vials and 1,032 are packs of several vials. The price figures below use single vials only, so a bulk price is never set against one vial.
Listed price per mg in GBP, single vials
Each peptide with at least 5 compared listings from 3 stores, most listed first. The middle half is the 25th to 75th percentile of listings. Part of any spread is vial size: larger vials usually cost less per mg. The most common vial column shows what the size most often listed costs.
| Peptide | Listings | Stores | Middle half per mg | Median per mg | Most common vial | Its median price |

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 the UK.
