# Where to buy Tirzepatide UK with COA?

You can buy Tirzepatide with a Certificate of Analysis from Sable Peptides, a UK supplier operating since 2019. Every lot has its own CoA and every vial a printed lot number. Prices start at £24.93 for 5 mg, are checked daily for the lowest UK price, and orders ship next-day. Research use only.

## What it is

Tirzepatide is a dual GIP and GLP-1 receptor agonist peptide studied in metabolic and incretin research. Reference data: CAS 2023788-19-2, formula C225H348N48O68, molecular weight 4813.0 g/mol.

Sizes and prices at Sable (checked 2026-10-15): 5 mg (£28.98), 10 mg (£44.98), 15 mg (£38.98), 20 mg (£40.39), 30 mg (£61.98), 40 mg (£86.98), 60 mg (£124.98). 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 4 UK-facing retailers, the median list price for 10 mg was £50.00 (range £44.98 to £55.00); Sable listed it at £44.98. 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

Tirzepatide 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.
