Certificates of Analysis (COAs) validate the identity, purity, and overall quality of a peptide — making them essential for maintaining research accuracy and credibility. At Oasis Labs, we recognize that too many COAs in the market are incomplete or missing key data, which can compromise results. That’s why we prioritize full, transparent documentation to support confidence in every product we deliver.
The COA you see on a product page came from an independent U.S. laboratory testing the same lot the vial in your shipment was filled from. Every vial ships with a QR code that links to our full COA library, so you can pull the matching document on demand.

-
01
Synthesis & intake
Each batch arrives from our ISO-certified U.S. facility with internal manufacturing records intact.
-
02
Independent third-party lab
Samples ship to an independent U.S. laboratory for HPLC purity and identity-focused analysis.
-
03
COA issuance & library publication
The lab issues a signed Certificate of Analysis. We pair it to the production lot and publish it in the COA library.

04
QR-linked vial
Every vial ships with a QR code that links to the full COA library — lookup by lot is one scan away.
Three commitments behind every certificate.
HPLC purity
High-performance liquid chromatography is the workhorse for the ≥99% purity claim. We don’t round up.
Identity confirmation
Mass-spec and analytical identity references confirm the molecule matches the label, not just the spec sheet.
Lot-level access
Every certificate is keyed to a production lot, so what’s on paper matches the vial in front of you.
The analytical methods behind every COA.
High-Performance Liquid Chromatography (HPLC)
HPLC is utilized by advanced testing laboratories to isolate and quantify peptide components with exceptional accuracy. Advanced detection methods, including UV detectors and mass spectrometers, are combined with HPLC to provide precise impurity detection and purity analysis.
UV Absorption Testing
HPLC integrated with UV detection technology provides clear visual representations (chromatograms) that confirm peptide purity and identify potential impurities by separating compounds clearly and accurately.
Mass Spectrometry (MS) — Molecular Identity Confirmation
To further confirm peptide identity, mass spectrometry analysis verifies molecular weight accuracy, reinforcing peptide authenticity and quality when used alongside HPLC.
