Beginner's guide to COAs (short)
A Certificate of Analysis, or CoA, is a document from a third party laboratory that shows the results of testing on a specific product. In the peptide space, vendors use them to prove their products are what they say they are.
The problem is that most people don't know how to read one, and vendors know that. A lot of CoAs floating around are stolen, faked, or so old they're meaningless. This guide will teach you exactly what to look for so you never get fooled.
