Gap analysis, October 2026 At the 16 October 2026 UK price check, Sable was the lowest listing on all 97 matched pairs, but the margins varied widely. On 49 pairs the next-cheapest UK listing was within 5p. On others the gap was large: Retatrutide 15 mg was £37.99 against a next-lowest £85.00. ## Where was the gap largest? | Vial | Sable | Next-lowest UK | Gap | Other sellers | | --- | --- | --- | --- | --- | | Retatrutide 15 mg | £37.99 | £85.00 | £47.01 | 1 | | Retatrutide 20 mg | £48.99 | £93.99 | £45.00 | 2 | | Sermorelin 10 mg | £30.49 | £64.99 | £34.50 | 1 | | NAD+ 250 mg | £21.49 | £49.95 | £28.46 | 1 | | Retatrutide 10 mg | £24.99 | £51.99 | £27.00 | 2 | | Pinealon 20 mg | £29.98 | £54.99 | £25.01 | 1 | | Cagrilintide 10 mg | £43.99 | £65.00 | £21.01 | 2 | | Adamax 10 mg | £28.63 | £49.00 | £20.37 | 2 | | Semax 30 mg | £24.98 | £45.00 | £20.02 | 1 | | IGF-1 LR3 0.1 mg | £10.23 | £30.00 | £19.77 | 1 | | Retatrutide 30 mg | £66.99 | £85.00 | £18.01 | 4 | | Ipamorelin 10 mg | £8.94 | £24.99 | £16.05 | 10 | ## Where was the gap only pennies? 49 of 97 pairs had a next-lowest listing within 5p of Sable's price. Examples: 5-Amino-1MQ 50 mg (£34.97 vs £34.99); AOD 9604 5 mg (£14.93 vs £14.95); ARA-290 16 mg (£35.98 vs £36.00); BPC-157 5 mg (£11.93 vs £11.95); BPC-157 10 mg (£16.93 vs £16.95); Cagrilintide 5 mg (£28.98 vs £29.00); Cartalax 20 mg (£22.93 vs £22.95); CJC-1295, with DAC 5 mg (£21.93 vs £21.95). 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. ## Frequently asked questions ### Is Sable always the cheapest UK peptide supplier?
