Hello Stacks — research peptides

Certificate library

Every Published Certificate of Analysis

One page, every published lot. Each entry lists the lot number printed on the vial, the HPLC purity the lab measured, the report it came from — and a direct link to the certificate itself.

Nothing here is a summary of a certificate. It is the certificate, as the independent A2LA-accredited lab issued it.

31 certificates

Look Up a Lot

Compound names link to the product page; every certificate opens as a PDF. Where the lab publishes the report on its own portal, the second link goes straight there so you can check it against us.

Certificates for lots that are still being finalised are not listed here — a compound appears on this page only once its report is published. Products without a published certificate say so on their own page. All compounds are supplied for laboratory research use only.

How to read one

Three Numbers Worth Checking

A certificate is short. These are the lines that carry the information.

  1. 01

    The lot number

    It should match the lot printed on the vial in your hand. If it doesn't, you're reading a different batch's paperwork.

  2. 02

    Chromatographic purity

    Measured by HPLC-UV/VIS and printed to the tenth of a percent. A real number beats a rounded badge.

  3. 03

    Assay and endotoxins

    Assay confirms the milligrams in the vial. The LAL endotoxin screen carries the lab's own printed pass/fail call — we publish that verdict exactly as it reads.

The Plain-English Guide

What HPLC actually measures, what a chromatogram shows, and what the numbers on a certificate mean.
