Top 10 peptide suppliers in the UK
Compare peptide suppliers, vial prices, bulk offers and UK delivery options.
Choosing a UK peptide supplier means looking beyond the price of one vial. BluePeak sells two-vial packs, Astra Labs gives a third vial free when you buy two, and XL Peptides sells multi-vial bundles. Below, we compare those offers alongside lab reports, payment options and delivery terms.
Every shop in the top 10 lists UK delivery on its own website.
Our order is 70% trust and 30% price. Trust is the PSV Trust Score. Price comes from the UK price index, which compares the same vial and pack across UK shops. A shop at the typical price gets half of the price points, and each 1% cheaper adds one point. How the price index works.
We read each shop’s delivery and payment pages on 30 September 2026. Prices in pounds are from the last 30 days and leave out postage and coupons.

Keep in mind. Hub dates come from batch codes, so open the Janoshik record to see the test date. The pages we read did not list payment methods.

What to check before you order in the UK
Check payment options before you order, because not every shop takes cards. Simply Peptides takes Pay by Bank or Bitcoin only, and Ascend Peptides UK takes PayPal, Open Banking or bank transfer. Free delivery starts at different amounts: £14.99 at Simply Peptides, £50 at Peptology Labs and £100 at BluePeak.
Open the lab report for your batch. The lab name, test date and batch number should match the vial you buy. Our certificate guide shows where to find them.
How the UK ranking works
The trust part uses four scores: our own lab test (40 points), external reviews (20), community feedback (15) and transparency (25). Without our lab test a score is out of 60. The shop with the highest trust score in this guide gets 100 trust points, and the others get a share of that. Scoring rules.
The price part uses matched vials only. Price index 100 gives 50 of 100 price points; 80 gives 70; 120 gives 30. A shop with no index gets 50, so a missing price does not move it up or down.
A shop with an open concern, such as a profile warning, reports of fake goods or lost orders, or a drug-maker lawsuit, is kept out of the top 10 but stays in the full list. Scores compare research suppliers only.
Questions about UK peptide shops
Is the cheapest UK shop ranked first?
No. Price is only 30% of the score. A cheap shop with thin lab evidence sits below a shop with strong, recent reports.
What does a price index of 85 mean?
The shop’s matched vials cost about 15% less than the typical price at other UK shops. An index of 100 is the typical price.
Why do some shops have no price index?
We need in-stock prices for at least three peptides, each also sold by two other shops. Until then, the shop gets the middle price score of 50.
Do all of these shops post from the UK?
Most do, but not all. Check the dispatch country, because parcels from abroad take longer.
Did PeptideScanner test these vials?
No. The shops paid for these certificates. A score out of 60 does not include our own lab test.
