Peptide identity, purity, potency, and stability testing explained.
Before purity or potency means anything, you have to know the peptide is the right molecule. Here is how LC-MS confirms molecular weight, and what common mass shifts reveal.
Read article →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.
Read article →Identity, purity, potency, stability: the four questions every peptide COA should answer, the analytical methods behind each, and how to read the results with a critical eye.
Read article →A peptide can be 99% pure by HPLC and still be only 80% peptide by mass. Here is why area purity and peptide content answer different questions, and why dosing depends on the one most COAs leave out.
