Certificates of Analysis — PowerfullyPeptides

A Certificate of Analysis (COA) is an independent laboratory report on a specific production batch. It verifies what the material is (identity), how pure it is (purity), and how much is in the vial (quantity). This page is the home of our COA library: each product below holds its published certificates.

Why we publish everything

In a market where certificates are hidden, redacted, or self-issued, we do the opposite. This is the whole brand, not a badge.

An independent lab, namedEvery certificate is issued by Janoshik Analytical, not by us. We are the laboratory's customer, nothing more.

Verifiable at sourceEach result carries a task number you can enter in the lab's public database. Check it yourself; don't take our word for it.

Independent testing has begun. Each certificate publishes on this page as results return, product by product, with its SHA-256 checksum and a link to the laboratory's public verification database, so every result can be checked at source. Not sure what a certificate should contain, or how to check one? See how to verify a peptide supplier — the checklist we publish for buyers, including for use on us.

Who does the testing

Testing is performed by Janoshik Analytical, an independent third-party laboratory specialising in peptide analysis (HPLC and mass-spectrometry methods). We are a customer of the laboratory and nothing more — results are published as issued.

Certificates by product

Lab supplies (such as bacteriostatic water and consumables) are sourced as manufactured, certified products and are not individually tested by us.

How to read and verify a COA

Identity — confirms the material is the named compound.
Purity — the chromatographic purity measured for the sample.
Quantity — the measured content per vial.
Verification — enter the certificate's task number in the laboratory's public database to confirm the result is genuine.
SHA-256 checksum — a fingerprint of the certificate file itself. Hash the file you downloaded and compare it to the checksum shown next to the certificate; if they match, character for character, the document has not been altered.

Verifying the SHA-256 checksum

A SHA-256 checksum is a 64-character fingerprint calculated from the exact bytes of a file. Change a single character in the file and the checksum changes completely, so it lets you prove the certificate you hold is byte-for-byte the one we published, with no trust required. When a certificate is published above, its checksum is shown beside it. Download the certificate, compute the hash on your own machine, and confirm the two strings match.

Windows (PowerShell):

Get-FileHash .\certificate.png -Algorithm SHA256

macOS / Linux (Terminal):

shasum -a 256 certificate.png

Compare the value it prints with the SHA-256 shown next to the certificate. A match means the file is authentic and untampered; a mismatch means the file you have is not the one we published — in that case, email us and do not rely on it.
