QSC Direct Labs
The public COA archive for QSC Peptidology. Every batch below cleared HPLC and LC-MS release testing — the PDF is the actual batch-specific report, not a template.
Not every historical batch is listed here — match the batch ID on your box label against the ID below before relying on a result.
These are the batches we sell. Wholesale 10-vial packs, delivered duties paid.

Purity (HPLC)
Chromatographic purity against our release cutoff, plus total and single related-substance (impurity) limits.
Identity (LC-MS)
Measured molecular mass checked against the molecule's theoretical mass — confirms it's the right compound, not just a pure one.
Residual solvents & moisture
Acetic acid, TFA, and Karl Fischer water-content results from the synthesis and lyophilization process, each against an acceptance limit.
Appearance & solubility
Physical checks — color, form, and solubility in water — that catch a batch gone wrong before the analytical results even come back.

Common questions
Is the PDF here the same report that ships with my order?
+
Yes — it's the actual batch-specific Certificate of Analysis, not a template. Match the batch ID on your box label against the ID listed here before relying on a result.
My batch isn't listed here — does that mean it wasn't tested?
+
No. Every batch is tested and gated on HPLC and LC-MS before release, regardless of whether it's published here. This archive is a growing subset, not the complete historical record — request your specific batch's report by ID if it isn't listed yet.
What does "Status: active" mean?
+
The batch has passed release testing and is currently in stock or was in stock within its retest window. A batch that's fully depleted or past its retest date is removed from this archive, though the underlying report is still available on request.
Is every batch independently (third-party) verified?
+
No — HPLC + LC-MS release testing applies to every batch. Independent Janoshik reports are published for selected samples at qscpeptidology.com/janoshik-reports; third-party testing isn't run automatically on every batch.
Can I verify a batch myself?
+
Yes. Keep the original packaging and the batch ID, and compare your own lab's result against the COA for that same batch ID.
Independent Janoshik reports are published for selected samples, not for every batch — see qscpeptidology.com/janoshik-reports and qscpeptidology.com/quality.
