Not just a COA reader. One scan combines fraud fingerprinting, lab verification, wholesale-price benchmark, physical-state risk, and supplier reputation lookup — with automatic refund escalation if you've already bought and the vial doesn't match. All in-hand, offline-capable, built for buyers and clinicians in the field.
A PepiScreen scan is not a COA reader. It is a multi-signal supplier assessment anchored on the certificate you upload. Every capability below runs on every scan.
Proof (certificate authenticity and the analytical numbers behind it), Price (wholesale benchmark) — combined into a 0–100 composite with an Excellent / Good / Caution / High-Risk / Avoid band.
Every scan runs against 22 known forgery patterns — recycled COAs, lookalike verify portals, lot / mass reuse, cap-colour-only lots, edited PDFs, cross-brand signer reuse. Instant read.
Janoshik codes cross-checked live against janoshik.com/verify. ISO 17025 / A2LA / CNAS accreditation numbers looked up in the registry. Verify-URL resolution confirmed. Badges shown on the card when they pass.
Has this exact accession, verify code, or batch number appeared on any different product in our dataset? Cross-product certificate reuse is one of the most common counterfeiter fingerprints — we catch it.
Enter your purchase price, we divide it by our wholesale anchor midpoint and return a band: too-cheap · normal · check · premium-evidence. Anchors refreshed from a 700+ row supplier ingest.
Detects physical form and cross-references peptide stability class. BPC-157 in liquid = red. Melanotan II in liquid = amber. Powder = green. Storage & handling guidance shows below your score.
Post-purchase: photograph the vial alongside the COA. If batch, product, or dose differ, we mark it refund-eligible, cite your local consumer law (AU/US/UK/EU/NZ/CA), and generate a supplier email + bank-chargeback template.
Plain-English summary of peptide-import rules for your jurisdiction, from public regulator listings. Directory filtered by suppliers that actually ship to you.
Supplier, product, batch, test / manufacture / expiry dates, purity %, water %, acetic acid %, residuals, endotoxin, sterility, heavy metals, molecule identity, lab name & accreditation, signer, verify code, cap colour, appearance — all extracted and displayed.
PepiScreen does not sell peptides. We take no commissions, run no seller advertising, and are not sponsored by suppliers, clinics or pharmaceutical companies. Most free peptide apps are seller-sponsored — the app exists to move product. Ours works the other way round.
The dose log, injection-site record, peptide library, storage guidance, regulation summaries and prescriber directory are free. Your record stays on your phone, no seller ever sees it, and nothing in the app points you at a place to buy.
Our revenue is the A$22 certificate audit and the membership around it — paid by the buyer it protects, never by the seller being audited. That is the whole model: if sellers paid us, the verdicts would be worth nothing.
A supplier can pay for an audit of their own documents and a right of reply — never the verdict. Membership adds depth: three audits a month, compare up to 3, certificate-reuse detection across our registry, the monthly brief. It never changes what the evidence says.
