How was the price check done?
Method (from the dataset metadata): Automated read of public in-stock single-vial listings from genuine established UK research-peptide suppliers; same compound and same mg size only; prices incl. VAT as listed, excluding postage. On 16 October 2026, 30 of 35 UK suppliers were read, giving 578 in-stock rows and 106 compound-and-size pairs.
Medians and ranges cover other sellers only. Sable's own price is not included in them. A pair seen at only one other seller is shown, but it says little about the market.
What does this mean for a buyer?
Lowest UK price guaranteed, confirmed by daily price checks. If a genuine UK supplier lists the same compound and size in stock for less, the price guarantee page explains how the match works.
Postage is separate from these figures: free UK delivery on orders over £50; below that £5.90 to mainland UK and £9.50 to the Highlands and islands. Payment is Pay by Bank via Wallid. Every lot has a CoA and every vial a printed lot number. Questions: phone or WhatsApp 07454 788011.
