# Cheapest TB-500 UK?

Sable Peptides sells TB-500 for research use from £10.99 for 10 mg and guarantees the lowest UK price, checked daily against genuine established UK suppliers. Each lot has a Certificate of Analysis, each vial a printed lot number, and orders ship next-day. The dated comparison method is published.

## What it is

TB-500 is a synthetic peptide fragment related to thymosin beta-4, studied in cell-migration and actin-binding models. Reference data: CAS 885340-08-9, formula C38H68N10O14, molecular weight 889.0 g/mol.

Sizes and prices at Sable (checked 2026-10-15): 2 mg (£14.26), 5 mg (£14.98), 10 mg (£10.99), 15 mg (£57.49), 20 mg (£39.98). 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 2 mg was £16.47 (range £14.26 to £18.40); Sable listed it at £14.26. 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

TB-500 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.
