Exact compound and form
The report names the exact compound and form represented by the listing.
A similar name, salt, sequence, or product category is not an exact identity match.Free 10-field document audit
Peptide COA checker.
Read the document before the headline purity number. Mark what is present, missing, or unresolved, then copy a neutral completeness summary.
Document checker, not product verification.The result cannot establish vial identity, chain of custody, sterility, safety, authorization, or suitability for use.

Loaded listing context
Tesamorelin 10 mg from Pepta Labs
Seller states independent HPLC purity and ESI-MS identity testing with a batch certificate available on request. Peptide Local did not sample the material.

Matching batch or lot
The report batch or lot identifier matches the item or listing it is claimed to support.
A generic certificate is not lot-specific evidence.Analysis and release dates
The report shows an analysis or release date plus any stated retest or expiry date.
A laboratory result is a dated observation, not a permanent product property.Named testing laboratory
The testing laboratory is named with a public contact or verification route.
The phrase third-party tested is incomplete without an attributable testing party.Verifiable report record
A report number, signed record, laboratory lookup, or direct verification link is present.
A screenshot or logo alone gives the reader no strong route back to the reported record.Sample submitter and custody
The document or supporting record identifies who selected and submitted the sample.
Seller-submitted testing and independently purchased testing have different custody limits.Purity method and result
A stated analytical method, numerical purity result, and acceptance limit are visible.
A large percentage or pass badge without the method and result context is incomplete.Separate identity evidence
An identity method and result are stated separately from the purity measurement.
Purity and identity answer different questions. One should not be inferred from the other.Instrument output
The report includes or links the relevant chromatogram, spectrum, peak table, or raw-result view.
Instrument output makes the represented result more inspectable, but still does not establish custody.Quantity kept separate
Any quantity or content claim has its own method and result rather than being inferred from purity.
A 99 percent purity result does not prove the amount of material in a vial.Do not merge the measurements
Four claims. Four different tests.
A complete-looking report can still be answering a narrower question than the seller’s headline claim.
Purity
A purity result describes the measured composition of the submitted sample under a stated method. It does not identify the sample unless identity is tested separately.
Identity
An identity result supports what the submitted sample was reported to be. It does not prove every vial sold came from that sample.
Quantity
Nominal milligrams and purity percentage are different measurements. Quantity needs its own method if it is claimed as a measured result.
Sterility
Purity or mass-spectrometry results do not establish sterility, endotoxin level, or suitability for administration.
Why these fields
Built from public laboratory-record principles.
FDA Q7A guidance describes batch-specific certificates, material name, batch number, release date, testing methods, numerical results, acceptance criteria, responsible parties, and laboratory records. NIST’s certificate definition adds intended use, certified values, uncertainty, methods, traceability, and validity.
Retail seller documents are not automatically GMP batch certificates or NIST reference-material certificates. This tool uses official frameworks to show which document fields are explicit and which questions remain open.
