A narrow gap is what a price-match policy produces: the price is set just under the cheapest verified competitor.
Is the gap to the median more useful?
For a typical buyer, yes. The median gap across all pairs was £10.05, against a median gap of £0.02 to the next-lowest listing.
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 the price guarantee?
Lowest UK price guaranteed, confirmed by daily price checks. Where the gap is pennies, a competitor's price change can close it. That is why the check runs daily and why the guarantee offers to beat a cheaper in-stock UK listing of the same compound and size.
