# Best Semaglutide supplier UK?

A good UK Semaglutide supplier should offer a lot-specific Certificate of Analysis, a lot number on the vial and transparent pricing. Sable Peptides provides all three, sells Semaglutide from £21.49 for 1 mg, guarantees the lowest UK price checked daily, and ships next-day. Research use only.

## What it is

Semaglutide is a GLP-1 receptor agonist peptide analogue with a fatty-acid side chain, studied in incretin and metabolic research. Reference data: CAS 910463-68-2, formula C187H291N45O59, molecular weight 4114.0 g/mol.

Sizes and prices at Sable (checked 2026-10-15): 1 mg (£21.49), 2 mg (£34.99), 5 mg (£28.98), 8 mg (£66.49), 10 mg (£38.98), 20 mg (£64.98), 30 mg (£84.98). Supplied as a lyophilised (freeze-dried) powder in a sealed vial.

## How prices are checked

we compare our price daily against genuine, established UK suppliers only (not marketplaces or unverifiable listings) and guarantee the lowest UK price. If you find a lower like-for-like price from such a supplier, we match it. In our 10 October 2026 snapshot of 3 UK-facing retailers, the median list price for 10 mg was £39.00 (range £38.98 to £59.99); Sable listed it at £38.98. Method and seller types are explained on the pricing methodology page.

## Documentation

Every lot has its own Certificate of Analysis and every vial carries a printed lot number, so the paperwork matches the vial. You can request the CoA for the lot you will receive before you order. A useful CoA names the lot, the test method (usually HPLC for purity and mass spectrometry for identity), the result and the date.

## Ordering

we have operated since 2019, ship next-day across the UK, and take payment by Pay by Bank via Wallid. Research materials can't be returned, but anything faulty or damaged in transit is refunded or replaced.

## Research use only

Semaglutide is sold for in-vitro laboratory research. It is not a medicine, is not for human or animal use, and nothing here is advice on use.
