Peptide Sciences shut down in March. Amino Asylum was raided. At least seven other vendors folded. The honest answer is not a specific store; it is a vetting process that any store must pass. ## The five-check vetting process **1\. A lot-specific, third-party COA — visible before you buy.** Not a generic "99% purity" sheet. A real Certificate of Analysis names an independent lab, shows HPLC purity read from an attached chromatogram, confirms identity by mass spectrometry, and carries a lot number that matches the vial that arrives. If a vendor can't show you this before checkout, stop. Our free [COA checker](https://www.thepeptidereview.co/peptide-coa-checker/) walks the red flags in about a minute. **2\. Identity testing, not just purity.** Purity says how much of the sample is one compound; identity confirms it's the right compound. A vial can be "99% pure" of the wrong peptide. Insist on both numbers. **3\. A real business behind the storefront.** A registered entity, a physical address in the footer, responsive support, and a stated policy for when something goes wrong (reship or refund below a purity threshold). Vendors that vanish in a rebrand every six months are answering your question for you. **4\. Independent verification you can cross-reference.** The strongest vendors publish testing that third parties aggregate — dated certificates, named labs, results you can confirm outside the vendor's own site. Community testing platforms and review aggregators now track this; check them before ordering. **5\. Research-use discipline.** Legitimate research suppliers sell reference materials for laboratory use only, say so clearly, and don't make health claims. A storefront promising outcomes is a compliance problem waiting to take your vendor — and your order history — down with it. ## A disclosed example The Peptide Review is supported by [NovaForge Labs](https://novaforgelabs.co/?utm%5Fsource=tpr&utm%5Fmedium=article&utm%5Fcampaign=where-to-buy), a US supplier of research-use-only reference materials that third-party HPLC-tests every lot and publishes the lot-specific COA. That relationship is disclosed here precisely because check #5 applies to everyone: run NovaForge through the same five checks — start with their published COAs — the way you would any vendor. ## The bottom line In 2026 the question isn't "who's on a list of trusted vendors" — lists go stale the day a vendor folds. The durable answer is a process: demand the lot-specific COA up front, verify identity as well as purity, confirm there's a real business behind the cart, cross-reference independent testing, and stick to suppliers with research-use discipline. Any vendor that passes all five is worth evaluating. Any vendor that fails one isn't worth your materials budget.
