Independent peptide screening, research and industry advocacy — helping people make more informed decisions through Proof, Price and Match.
A peptide order is often US$200–300 for a product you cannot see inside, and the certificate in the listing is the only evidence a buyer or prescriber gets in advance. PepiScreen reads that certificate the way a forensic auditor would — is the lot number real and unique, did the laboratory we have rated actually issue it, does the seller have a name, does the verification route resolve? Then we show you where that price sits for that molecule, at that vial size, against 3,000+ benchmarked prices from supplier catalogues. When your order lands, scan what came in the box and we will tell you whether it matches what you were sold. This is our process.
Independent supplier evidence, prescriber consultation, and private laboratory analysis answer different questions. They are complementary, not alternatives. PepiScreen provides the first — the research layer that sits alongside a peptide-literate prescriber and, where the specific vial matters, a private lab test.
These are not substitutes for one another. A prescriber provides clinical judgement. A laboratory measures what is in a specific vial. PepiScreen provides independent supplier evidence — the research layer. All three have distinct roles, and no one of them replaces another.
Three checks on every peptide purchase: two on the paperwork before you pay, one when the vial arrives.
PepiScreen makes peptide screening and research easier by answering the three things every buyer is otherwise asked to take on trust — Proof, Price and Match. Two checks on the paperwork, one when the vial arrives, informed by our growing research across peptide providers worldwide and by reviews from real buyers.
Proof and Price on the paperwork, Match when the vial arrives — so the three things you can't easily judge for yourself become one clear verdict, and stay checked after the money leaves.
A three-step process — upload, forensic audit, scored verdict — backed by AI and the real analytical data inside the certificate, not marketing claims.
Every verdict draws on our growing research base of peptide providers and resellers, plus buyer reviews gathered internally and externally (Trustpilot, Reddit) — folded in as signals, never a substitute for the documents.
A peptide order is often US$200–300 plus shipping — for a product you can't see inside. A single screen is the cheapest check you'll run: it replaces guesswork with data, showing whether the paperwork actually proves what's claimed, upfront. Your first review is free.
