Process

From Synthesis to Your Door

Every Vertex Labs compound passes through four non-negotiable verification stages before it's cleared for dispatch.

01
Synthesis & Sourcing
Compounds sourced from verified GMP-compliant synthesis facilities. Full chain of custody documentation retained.
02
In-House QC Check
Visual inspection, weight verification, and preliminary solubility testing performed at our facility before external dispatch.
03
Third-Party HPLC Analysis
Sample sent to an ISO 17025 accredited independent laboratory. HPLC-UV analysis, mass spectrometry identity confirmation, and endotoxin testing performed.
04
COA Issued & Dispatched
Certificate of Analysis issued by the laboratory, linked to the batch number, and made publicly available. Only approved batches are dispatched.

Sample Document

Every Batch Has a Certificate.

Our Certificate of Analysis is issued by an independent, ISO 17025 accredited laboratory — not self-certified. Every field is documented: purity, method, standard, accreditation number, and result.

Batch numbers are traceable. COAs are publicly accessible. This is what accountability looks like.

Independence Matters

Why Third-Party Testing?

Self-certification is not verification. Here is why independent testing is the only standard that matters.

True Independence
An independent laboratory has no commercial incentive to pass your product. Their only incentive is accuracy. That is the point. Self-testing creates a conflict of interest that renders results meaningless for research purposes.
ISO 17025 Standard
ISO 17025 is the international standard for testing and calibration laboratory competence. It mandates documented procedures, equipment calibration, analyst qualifications, and inter-laboratory validation — not just a result, but a defensible, repeatable methodology.
Full Documentation
Every COA we publish includes the laboratory name, accreditation number, analytical method, reference standard, and instrument used. You can verify the lab independently. No black boxes. No vague "in-house tested" claims.
Transparency
