UK peptide shop lot number vial?
At Sable Peptides every vial has its lot number printed on it, and every lot has its own Certificate of Analysis. That lets a lab tie the exact vial on the bench to its purity and identity results. Request the CoA for your lot before or after ordering.
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.

Key terms
- Lot number
- A lot number, or batch number, is an identifier assigned to a particular quantity of material produced under uniform conditions. It links a product to its manufacturing and quality-control records, including the certificate of analysis, and allows a researcher to trace results back to the specific material used.
- Glass vial
- A glass vial is a small container used to store laboratory materials. Peptides are commonly supplied in borosilicate glass vials sealed with rubber stoppers and aluminium crimp caps.
