Educational articles on the peptides in our catalog — mechanisms, published studies, and research-use context.
A Certificate of Analysis is only useful if you can read it. Here is exactly what each section of a peptide COA means — HPLC purity, mass spectrometry identity, and the lines most buyers skip.
Purity is the headline number on every peptide listing — but 99% purity and 99% peptide content are different things, measured differently. Here is what the number does and doesn’t tell you.
Both can produce a COA. Only one removes the conflict of interest. Here is why independent, third-party testing is the higher standard of evidence for a research peptide’s purity and identity.
A COA is only worth as much as its authenticity. These are the concrete tells that separate a genuine, batch-specific lab report from a recycled image or a fabricated one.
A principles-first framework for evaluating any research peptide source — built around verifiable evidence, not marketing claims. Use it to judge transparency, testing, and reliability.
