COA Process
How every P3X Labs batch is verified, and how to read a Certificate of Analysis with confidence.
Certificate of Analysis
Understanding COA standards
A Certificate of Analysis (COA) is the document that proves what is actually in a vial. At P3X Labs, every batch is verified by independent, accredited laboratories before it is labeled and shipped, and every result is published to a batch-specific COA you can pull by scanning the vial. This page explains how that testing works, and how to read a COA critically.
Why COAs matter
A COA confirms the identity, purity, and quality of a compound, it is what separates a verified research compound from an unknown one. The problem: many COAs in the market are incomplete, missing chromatograms, or never independently verified, leaving researchers with results they cannot trust. Every P3X lot ships with a complete, independent COA precisely because incomplete testing undermines the research it is meant to support.
How we test
Our laboratory partners use high-end analytical methods, not the generic, non-standardized testing many low-cost suppliers rely on.
HPLC
High-Performance Liquid Chromatography
Separates a compound into its components to detect even trace impurities, reported as a purity percentage of the total peak area.
Mass Spectrometry
Molecular identity confirmation
Matches the measured monoisotopic mass against the expected value for the declared structure, confirming the compound is what the label says.
Endotoxin (LAL)
Limulus Amebocyte Lysate assay
Screens for bacterial endotoxin and reports the result in EU/mg, a measure many suppliers skip entirely.
Net Fill & Mass
Content verification
Confirms the vial's actual content against its declared amount, so the labeled quantity is the delivered quantity.
Generic testing methods, outdated, non-standardized, or unverified , cannot provide this level of confidence. We do not use them.
How to read a COA
Key data to look for
- Testing methodology: HPLC and MS named explicitly, not just a bare purity number.
- Purity percentage: supported by chromatograms and an impurity breakdown.
- Chromatograms: labeled peaks with retention time and area percentages.
- Identity confirmation: measured mass matched to the expected value.
- Certifying analyst: signed and dated by a qualified chemist.
Red flags
- Vague or missing descriptions of the testing methods used.
- No chromatograms or visual data behind the purity claim.
- Purity percentages that don't agree across labs.
- Unsigned or undated certificates.
What makes P3X different
- Every lot is tested by independent, accredited laboratories, including Freedom Diagnostics Testing, Vanguard, and ILS.
- COAs include the full data set: chromatograms, impurity breakdown, and molecular confirmation.
- Lot-level traceability in the canonical FDT-YYYY-NNNNNN format, from synthesis to the shipping label.
- A scannable QR on every vial opens that batch's COA directly.
Verify any lot
Every vial ships with a lot number in FDT-YYYY-NNNNNN format and a QR code linking directly to its batch COA.
