Peptidegurus vs another vendor I'm weighing — and the listings for Peptidegurus aren't telling me much. Do they actually list full sequence, molecular weight, purity method, and batch/lot identifiers for each peptide, or just compound names? That's the first thing I can't pin down.
Second, are the COAs batch-specific, and can you see them before you buy? Want HPLC/MS chromatograms, testing lab name, date — not a generic sheet. Third, what countries.
Still nothing on that from what I can find online, and public listings are thin. Anyone actually ordered and can fill in the gaps?
