About ChemVerify and our methodology
ChemVerify compares research-peptide vendors by price per mg and publishes laboratory evidence: certificates of analysis per batch and samples that ChemVerify buys itself and has tested by an independent laboratory. ChemVerify does not sell peptides and gives no medical advice; all products are for laboratory research only.

How we test
- ChemVerify orders the sample from the vendor like any customer and pays for it.
- An independent laboratory analyses it, depending on the order: purity by HPLC, content against the label, endotoxin and, where measured, identity by LC-MS and heavy metals. Every record names the laboratory.
- Every report is published in full with the dates of purchase, receipt and analysis, including samples that fail.
- Ratings and the ChemVerified seal follow fixed criteria that are the same for every vendor.

Certificates of analysis from vendors
Besides our own samples, we collect certificates of analysis per batch, each with its batch number and the laboratory that issued it. These are documents issued for the vendor: a batch record shows what the laboratory reported; it is not a test by ChemVerify. Search batch records
How ChemVerify is funded
- Commissions: when you buy through one of our links or discount codes, the vendor pays ChemVerify a commission. It costs you nothing extra.
- Listing fees: new vendors pay a one-time registration fee of €400 and €25 per listed peptide (net). Individual agreements are possible.
- Commissioned tests: a vendor can have a peptide tested for the ChemVerified seal for €1,000 (net) per peptide; a listing requires at least one tested peptide. ChemVerify also tests on its own initiative.
- Links and discount codes that earn ChemVerify a commission are marked as advertising.
Who pays has no influence on prices, measured values, ratings or whether a result is published. Whether and how prominently a vendor is listed can depend on these business relationships.
What a result does not say
A test describes one sample from one vendor at one point in time. It says nothing about other batches, about effects or about safety in humans. We do not test every vendor or every product; which samples exist depends on commissioned tests and our own choice, and the list of tests shows how they are distributed across vendors.
