Thinly stocked compounds, October 2026 At the 16 October 2026 UK price check, 34 of 97 matched research peptide pairs were stocked by only one or two other UK sellers. Examples include ARA-290 16 mg, vilon 20 mg, cagrilintide 5 mg and FOXO4-DRI 10 mg. For these, Sable's lowest-price position rests on one or two real comparisons, and availability matters as much as price. ## Which pairs were thinly stocked? | Vial | Other sellers | Lowest other | Sable | | --- | --- | --- | --- | | ARA-290 16 mg | 1 | £36.00 | £35.98 | | BPC-157 20 mg | 1 | £40.00 | £34.99 | | CJC-1295, with DAC 10 mg | 1 | £34.99 | £34.97 | | Cagrilintide 5 mg | 1 | £29.00 | £28.98 | | IGF-1 LR3 0.1 mg | 1 | £30.00 | £10.23 | | MOTS-c 5 mg | 1 | £19.50 | £9.85 | | NAD+ 100 mg | 1 | £19.95 | £16.99 | | NAD+ 250 mg | 1 | £49.95 | £21.49 | | PEG-MGF 5 mg | 1 | £32.00 | £25.99 | | Pal-GHK 10 mg | 1 | £24.95 | £20.98 | | Pinealon 20 mg | 1 | £54.99 | £29.98 | | Retatrutide 15 mg | 1 | £85.00 | £37.99 | | Semax 30 mg | 1 | £45.00 | £24.98 | | Sermorelin 10 mg | 1 | £64.99 | £30.49 | | TB-500 20 mg | 1 | £40.00 | £39.98 | | Tirzepatide 5 mg | 1 | £24.95 | £24.93 | | Vesugen 10 mg | 1 | £44.95 | £39.50 | | Vesugen 20 mg | 1 | £35.00 | £21.49 | | Vilon 20 mg | 1 | £35.00 | £34.98 | | AOD 9604 2 mg | 2 | £22.90 | £14.29 | | Adamax 5 mg | 2 | £39.99 | £34.93 | | Adamax 10 mg | 2 | £49.00 | £28.63 | | Cagrilintide 10 mg | 2 | £65.00 | £43.99 | | Cartalax 20 mg | 2 | £22.95 | £22.93 | | Dihexa 10 mg | 2 | £45.00 | £44.98 | | FOXO4-DRI 10 mg | 2 | £50.00 | £49.98 | | Follistatin 344 1 mg | 2 | £62.90 | £49.97 | | Hexarelin 5 mg | 2 | £25.00 | £16.99 | | Ipamorelin 2 mg | 2 | £9.50 | £7.96 | | Retatrutide 5 mg | 2 | £20.95 | £16.93 | | Retatrutide 10 mg | 2 | £51.99 | £24.99 | | Retatrutide 20 mg | 2 | £93.99 | £48.99 | | SLU-PP-332 5 mg | 2 | £39.99 | £38.98 | | Sermorelin 2 mg | 2 | £13.95 | £12.93 | ## Why are some compounds thinly stocked? - Unusual vial sizes (for example 15 mg and 20 mg incretin vials, or 20 mg bioregulator vials) - Hard syntheses: long, lipidated or D-amino-acid peptides - Recombinant proteins that need expression capacity - Newer compounds with a small research base ## How should a buyer judge a thin market? With one or two comparisons there is no meaningful median, so look at the evidence directly: is the competing listing in stock, the same size and the same compound? Then check identity data more carefully, because rarer compounds get less independent scrutiny. Every Sable lot has a CoA and every vial a printed lot number. ## 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. ## Frequently asked questions ### Which research peptides are hard to find in the UK?
