This page is the checklist the Novusyn Research desk works through when documenting a research-use peptide supplier, written so any reader can run the same six tests: the lab name test (demand the actual laboratory's name, not "an independent lab"), the verify test (punch the report number into the lab's own portal), the batch test (per-lot certificates, not one PDF for the whole catalog), the date test (certificates older than twelve months deserve a refresh request), the panel test (identity, purity, sterility, endotoxin, heavy metals — not purity alone), and the catalog test (coverage across the catalog, not just the bestseller).
None of these tests produce a score, and none of them guarantee safety. A checkmark means we saw the document and it looked real; it does not mean we tested a vial ourselves. The page also lists quick red flags — vague lab language, stock photos, no business registration, prices far below market, and review text that repeats — and explains how the desk's three evidence lanes (provider-verified, public documents, account-forward) differ from one another without one being a recommendation.
Readers can put the checklist to work on the Supplier Desk, line paperwork up side by side on the compare tool, check a report number against the testing labs list, and see how evidence types are organized on the transparency layers page. To learn how we read the paperwork itself, start with how to read a certificate of analysis and peptide purity explained. Suppliers can request a review via the application page, readers can nominate a supplier via the suggestion form, and broken links or certificates that won't verify can be reported on the contact page. Our independence and disclosure rules live in Editorial Standards.
