Read the paperwork first.

Guides on COAs, HPLC purity, endotoxin testing, and how to tell a real research peptide supplier from the rest.

Learn to read a peptide COA: match the lot number, verify HPLC purity, confirm mass-spec identity, and check the endotoxin result. A field guide.

How research peptide purity is verified: HPLC for purity, mass spec for identity, and LAL for endotoxin, all documented on a lot-matched COA.

Third-party HPLC testing proves lot purity and separates in-house claims from independent evidence. What it shows, and what it doesn't.

What LAL endotoxin testing is, how the Limulus Amebocyte Lysate assay works, and why the endotoxin line on a peptide COA matters.

A vetting checklist for research peptide suppliers: lot-matched COAs, third-party HPLC, mass spec, LAL endotoxin, and named labs. What to verify.

Research use only (RUO) explained: what the designation means for handling, documentation, and labeling of research compounds, and why it matters.

NAD+ research reference: what it is, its research context, how purity is verified by HPLC and LAL, and lab storage and handling notes.
