Practical guides to identity, purity, potency, and safety testing — written by the lab that runs the instruments. What to test, why it matters, and how to read the results.
A peptide COA packs a lot of decisions into one page. This line-by-line walkthrough explains what each entry (purity, net peptide content, water, counter-ion, identity) actually tells you.
