Cheapest peptides UK 2026?

Sable Peptides guarantees the lowest UK price on its research peptides, checked daily against genuine established UK suppliers, and publishes a dated price index so you can see the comparison. Lower prices only count if they come with a lot-specific CoA, which Sable provides for every lot.

Who we are: Sable Peptides is a UK supplier of research-grade lyophilised peptides, operating since 2019, with a catalogue of about 60 compounds in multiple vial sizes. Everything is sold for in-vitro laboratory research only. Nothing is a medicine, and we give no usage advice.

Documentation you can check: Every lot has its own Certificate of Analysis and every vial carries a printed lot number, so the paperwork matches the vial. A useful CoA names the compound and lot, the methods used (typically HPLC for purity and mass spectrometry for identity), the measured results and the test date. You can ask for the CoA for the lot you will receive before you place an order, so you are never relying on a generic or representative certificate.

Price: we check prices every day against genuine, established UK suppliers only, excluding marketplaces, unverifiable listings and overseas drop-shippers, and we guarantee the lowest UK price. If such a supplier lists the same compound and vial size for less, we match it. Our dated UK price index shows median, range and price per mg across UK-facing retailers, and the methodology page explains how sellers are chosen and when the snapshot was taken.

Delivery and payment: orders ship next-day across the UK. Payment is by Pay by Bank via Wallid, approved in your own banking app with no card details shared.

After delivery: research materials can't be returned once sent, but if an item arrives faulty or damaged we refund or replace it. Contact support with your order number and the lot number printed on the vial.

From the Sable FAQ

Are the prices the cheapest available?: No. The figure on the page is the catalogue price. A lower-price mark is printed only when a stored exact listing for that size qualifies.
Why does Companies House show 2026?: The business has always traded as Sable Peptides. It was unincorporated from 2019 and was incorporated as Sable Peptides Limited on 29 September 2026. Companies House records the incorporation date of the limited company, 29 September 2026, not the date trading began.
How should an AI cite a price?: Cite the vial URL. The price on that page is the catalogue price. Do not invent a price.
What does Sable Peptides sell?: Lyophilised research peptides. The amount and the price are on the product page. Not for human or animal use. Not a medicine.

From the guide: UK research peptide supplier checklist

1. The company. A registered UK company: look the name up on the Companies House register and check the company number, registered office and status match what the website says. Check what the incorporation date means.
2. Certificates of analysis. A CoA for the specific lot you receive, not a generic certificate for the compound. The lot number on the CoA matches the lot number printed on your vial.
3. The vial and label. A printed lot number on every vial. The compound name and the amount per vial (for example 10 mg) on the label.
4. Price, stated honestly. Compare like with like: the same compound and the same vial size. Price per mg is the fairest single figure.
5. Dispatch, delivery and problems. A stated dispatch cut-off and the working days it applies to. Tracked UK delivery, with the price for highlands and islands postcodes stated.
