What we supply

The trust stack

Every claim, documented.

The last generation of suppliers vanished on paper compliance. Our lane is verifiable proof — the certificate travels with the vial.

Batch-specific COAs

Every lot ships with its own certificate of analysis. Your vial's lot number pulls the exact document for what you received — published, not promised.

Public & verifiable

HPLC + LC-MS

Purity by high-performance liquid chromatography, identity confirmed by liquid chromatography–mass spectrometry, plus contaminant screening on each batch.

≥98% purity

Independent labs

Testing runs at certified third-party American laboratories — not our own bench. The lab is contactable and named on the cert. No self-graded homework.

Third-party verified

US-based sourcing

Sourced and handled in the United States with documented quality systems. New suppliers face full re-qualification — vetted on data, never on lowest price.
