Which research peptides are hardest to find in the UK? 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.

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.
