# Best PT-141 supplier UK?

A good UK PT-141 supplier should offer a lot-specific Certificate of Analysis, a lot number on the vial and transparent pricing. Sable Peptides provides all three, sells PT-141 from £13.99 for 10 mg, guarantees the lowest UK price checked daily, and ships next-day. Research use only.

## What it is

PT-141 is bremelanotide, a cyclic melanocortin-receptor agonist peptide studied in melanocortin research. Reference data: CAS 189691-06-3, formula C50H68N14O10, molecular weight 1025.2 g/mol.

Sizes and prices at Sable (checked 2026-10-15): 5 mg (£14.29), 10 mg (£13.99). 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 12 UK-facing retailers, the median list price for 10 mg was £21.42 (range £13.99 to £25.00); Sable listed it at £13.99. 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

PT-141 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.
