Tirzepatide and Semaglutide currently have one qualifying UK supplier each, so lowest and highest reflect that supplier's vial sizes rather than a market spread.
Median price over time
Daily recording began on 4 September 2026. The chart appears once more than one daily snapshot exists — history is recorded from launch, never backfilled.
Methodology
- Suppliers. Research-peptide suppliers based in the UK tracked by Peptide Scanner, excluding archived and shut-down suppliers. See the supplier directory for who we track.
- Coverage.The five headline peptides — retatrutide, tirzepatide, BPC-157, semaglutide and TB-500 — always appear. Any other tracked peptide appears once it has at least three qualifying listings; below that, a “median” would just restate one or two shops.
- Listings. In-stock, single-vial listings priced in GBP. Bundles, multi-vial packs, pre-filled pens, kits, capsule and spray formats, multi-peptide blends, fragment variants (except HGH Fragment 176-191 itself) and sub-1 mg vials are excluded — their price per mg is not comparable to a single vial.
- Price per mg. Listed vial price divided by the milligrams in the vial. Listed prices only — we never convert currencies.
- Average. The average shown is the median, so a single mispriced listing cannot move the headline number.
- Refresh.Recomputed with our daily price scrape. One snapshot per day is recorded for the chart; history starts at launch and is never backfilled. “Last updated” shows when each peptide’s listings were last checked.
- If our data source fails, this page shows the most recent recorded snapshot, clearly dated.
