# BPC-157 vs TB-500?

BPC-157 and TB-500 are different research compounds. BPC-157 is a synthetic 15-amino-acid peptide (pentadecapeptide) based on a partial sequence of a gastric protein; TB-500 is a synthetic peptide fragment related to thymosin beta-4. They are not interchangeable and there is no published head-to-head comparison. Sable sells both for research use only, each with a lot-specific CoA.

## BPC-157

a synthetic 15-amino-acid peptide (pentadecapeptide) based on a partial sequence of a gastric protein, studied mainly in rodent and cell models of tissue and gastrointestinal repair.

## TB-500

a synthetic peptide fragment related to thymosin beta-4, studied in cell-migration and actin-binding models.

## 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 11 UK-facing retailers, the median list price for 5 mg was £15.99 (range £13.47 to £19.99); Sable listed it at £13.47. 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

BPC-157 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.
