Every check we ran matched the label.
Peptide certificate verification
Verify a peptide certificate before you trust the label
Upload a peptide certificate of analysis and compare it with the label claim, issuing laboratory, analytical methods and recall records. You get an itemized result, including what could not be confirmed.

The four answers
Caution
Nothing contradicts the label, but information is missing.
Fail
A measured value contradicts the label, or the lot was recalled.
Not verified
We could not read enough of the document to judge it.
Four words, fixed meanings. We do not publish a trust score—a single number would hide which check failed.

A PDF or photo of the printed sheet. Add the lot number from the vial.
We run nine checks
Purity, identity, impurities, lot, dates, methods, lab accreditation and recalls.

One verdict, then every check line by line—including what we could not confirm.
Evidence independent of commerce
The library labels the strength of human evidence and current regulatory context. Commercial links are disclosed and never affect verification or evidence labels.

What Peptely will never do
The restraint is the product
Commercial links may exist, but they never become treatment guidance or alter Peptely’s evidence and verification output.
- Recommend a dose, schedule or protocol
- Let affiliate compensation alter a result
- Present a vendor link as proof of quality
- Reduce a certificate to a trust score
