Third-party lab results, and the labs that issue them
We publish every lab result we receive — pass or fail — each one shown against the source and size it was taken from, and labelled by who had it run. The labs that issued them include Freedom Diagnostics, Janoshik and Accumark Labs. We don't test every batch: a COA covers only the lot it names, and there's no guarantee an order ships from a tested lot. The library at /verify shows exactly which lots we hold results for.
How we publish lab results
Each certificate we publish is the lab's own document, and the library shows the issuing lab wherever our record names it. We publish every result we receive, pass or fail, and a COA stands for the lot it names, never for everything sold after it.
The lab's own document
Every COA we publish is the lab's own document; the library shows the issuing lab wherever our record names it. There's no upload form: a certificate a buyer sends us is published once we've confirmed it against the lab's own copy, and it's labelled customer-submitted.
99%+ purity, guaranteed
If an independent lab test of your batch comes back under 99% purity, we reship it free or refund the order — your choice.
No cherry-picking
We publish every lab result we receive, pass or fail, so a vendor can't surface only its best lot. Every result we hold for a product is in its test history.
Lot-specific, not a stock COA
Each result stands for the lot it names only — never a stock certificate for everything sold after it. We don't test every batch, and there's no guarantee an order ships from a tested lot.
Sources compared head-to-head
Each product lists every source that carries it, so you can compare price and the lab results we hold per source, and choose for yourself.
A public record, result by result
Every certificate we publish stays in the product's test history and the COA library, pass or fail, so the record builds one result at a time.
Two of the sources we list, Orchid Cloud and Attestia Labs, are tracked on public independent lab databases — Finnrick and Janoshik — third parties we don't control. The COA count below is their combined published total:
Local warehouse → your door
Many sources ship from in-region warehouses — in the US, UK, EU, Australia, and Canada — for fast local delivery; others ship direct from the manufacturer. Cutting out the US retail middleman is why your order costs 10–12× less than the same compound from a domestic shop.
Regional warehouse
Ships from a US, UK, EU, Australia or Canada warehouse — or direct
Fast in-region shipping
Your door
Tracked delivery to your address
Fast & tracked
Sources ship from their own regional warehouses (US, UK, EU, Australia, Canada) or direct from the manufacturer. Peptuvia is the marketplace, not the manufacturer — so you get the same compound without the US retail markup. See every warehouse on the map.
All prices are in US dollars (USD). Kit prices exclude shipping; each vendor charges its own shipping rate.

What the tests measure
HPLC — High-Performance Liquid Chromatography
Separates the sample into its components and quantifies how much of the target peptide is present relative to impurities. This is where the purity percentage comes from.
Mass Spectrometry
Confirms identity by measuring the molecular weight of the compound. It answers a different question than HPLC: is this actually the peptide it claims to be?
Other assays
Some certificates also report an endotoxin (LAL assay) or heavy-metal (ICP-MS) result. Where one does, it shows on that lot's verification page next to the purity figure.
How to read a COA
- IdentityMass spec confirms the molecular weight matches the target peptide. Look for “confirmed.”
- Purity %The HPLC peak area for the target compound. We treat ≥98% as a pass.
- LotTies the result to the one lot it names: a printed lot number or, for some vendors, the cap and seal colour. Search it on our verification page.
- Test date & labWhen and where the analysis was run, with the analyst's signature or stamp.
