About PeppyCheck
A peptide transparency and verification platform built for the research community.
Why We Built This
The peptide market has a trust problem.
Suppliers claim their products are pure. Certificates of Analysis get shared on product pages. Purity percentages look impressive. But for anyone who has spent time in the peptide community, a nagging question remains — how do you actually know?
A COA on a supplier's own website tells you what the supplier wants you to see. A purity percentage without an independently verified lab report behind it is just a number. And when you're making research decisions, "just a number" isn't good enough.
We built PeppyCheck because this information gap shouldn't exist. The tools to verify peptide documentation already exist — independent laboratories, report reference numbers, verification portals. What was missing was a neutral platform that did the work of connecting those tools to the people who need them.
That's what PeppyCheck is.
What We Do
PeppyCheck is a peptide transparency and verification platform. We maintain a searchable database of peptide suppliers, their products, and their batch documentation. For every batch listed on our platform we independently verify the documentation — contacting the issuing laboratory directly to confirm the report is authentic.
We also host community reviews at three levels — supplier, peptide, and batch — so that real user experiences sit alongside verified documentation. Because even a perfectly authentic COA tells you less than hearing from ten people who have actually used that specific batch in their research.
Every batch on PeppyCheck has a verification report. Search a supplier, find a peptide, look up a batch number — and see exactly what documentation exists, whether we've independently confirmed it, and what the community has experienced. Transparent, structured, and independently verified.

What We Are Not
Not a Laboratory
We do not physically test peptide samples. We verify the documentation supplied by laboratories and suppliers.
Not a Marketplace
We do not sell, distribute, or manufacture any products. We are an information and verification platform only.
Not Affiliated
No supplier can pay to improve their verification status or remove negative reviews. Our independence is non-negotiable.
Not Advisory
We provide information. What you do with it is your decision. Nothing on PeppyCheck constitutes advice of any kind.
How We Stay Independent
PeppyCheck is funded by supplier subscriptions and user memberships. Suppliers pay to list and manage their profiles. Users pay a small membership fee for full access to batch reports and community features.
This model means our interests are aligned with accuracy and trust — not with any particular supplier's sales figures. A supplier cannot pay to hide a bad review or improve a verification status they haven't earned. The platform only works if users trust it, and users only trust it if it's genuinely independent.
We publish our verification methodology in full because transparency isn't just something we ask of suppliers — it's something we hold ourselves to as well.
How We Verify →The Community
PeppyCheck wouldn't exist without the peptide community — the researchers, biohackers, and informed users who have been asking hard questions about supplier quality for years. The blind testing pools, the forum threads, the groups sharing lab results — this community created the demand for what PeppyCheck provides.
We are building this platform for that community. Not for the suppliers who are doing the right thing and have nothing to hide — though we hope to be genuinely useful to them too. But primarily for the researcher sourcing a compound, wondering if what's documented matches what's inside.
That researcher deserves better information. PeppyCheck is our attempt to provide it.
