How to Read and Verify a Peptide COA
“A Certificate of Analysis (COA) is the record of what a specific peptide batch was tested for and what the results were. This guide explains each section of a COA, the warning signs of an unreliable one, and how to verify a Geno Bio Canada COA by lot number.”

Scientific Research Overview
Abstract & Executive Summary
A Certificate of Analysis is the single most useful document a research peptide supplier can provide. It is the written record of which tests were run on one production batch, which methods were used, what the acceptance limits were and what results were obtained.
Reading a COA well takes only a few minutes once you know where to look. This guide walks through each section in order, lists the warning signs of an unreliable certificate, and shows how to verify a Geno Bio Canada COA online.

What a COA Is
A COA is issued for one production batch, identified by a lot number. It lists the tests run on that batch, the method used, the acceptance limit and the result.
A COA only describes the batch printed on it. The first check is always that its lot number matches the vial in front of you.

Key Study Highlights
One batch only
A COA covers the lot number printed on it, nothing else
Purity and identity
Look for both an HPLC result and a mass spectrometry result.
Raw reports
Chromatograms and spectra are stronger evidence than a number alone.
