# Where to buy Tesamorelin UK with COA?

You can buy Tesamorelin 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 £19.93 for 2 mg, are checked daily for the lowest UK price, and orders ship next-day. Research use only.

## What it is

Tesamorelin is a stabilised 44-amino-acid GHRH analogue studied in growth-hormone-axis research. Reference data: CAS 218949-48-5, formula C221H366N72O67S, molecular weight 5136.0 g/mol.

Sizes and prices at Sable (checked 2026-10-15): 2 mg (£19.93), 5 mg (£24.97), 10 mg (£28.98), 20 mg (£74.98). 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 5 UK-facing retailers, the median list price for 2 mg was £22.00 (range £19.93 to £29.00); Sable listed it at £19.93. 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

Tesamorelin 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.
