Research compounds,
on the record.

Every vial carries a batch number. Every batch is independently assayed, and the certificate is published against that number — so the paperwork always matches the vial in your hand, not the product in general.

BPC-157 10 mg research vial
NW-BPC-0001 Assay in progress
Our standard

Every batch is independently assayed — and the report is published against the number on your vial.

Most suppliers print the same purity figure with no batch number beside it, and no report you can open. We do it the other way round: every vial carries a Northwest Peptides batch number, every batch goes to an independent laboratory, and the certificate is published in our open assay ledger against that exact number — so you can match the paperwork to the vial in your hand.

The ledger is public and always current, including while a batch is still with the lab. Our opening batches are in assay now, with certificates due 27 August 2026.

How an order is recorded

  1. 01

    Batched on arrival

    Stock is assigned a Northwest Peptides batch number before it is listed. That number is printed on the vial and shown on the product page.

  2. 02

    Assayed independently

    A sample from each batch goes to a third-party laboratory. We do not test our own material, and we do not publish a purity figure we generated ourselves.

  3. 03

    Report published

    The certificate is published against the batch number, so the report can be matched to the vial you received rather than to the product in general.

  4. 04

    Dispatched

    Orders placed before 12:00 are dispatched the same working day by Royal Mail Tracked 24, to UK mainland and Northern Ireland.
