Independently
verified.
Lot by lot.
Every NZM compound is synthesized in EU-certified facilities and verified by Janoshik Analytical, Europe’s reference laboratory for peptide purity assessment. We don’t run the analytics ourselves — that’s the entire point.
Each Certificate of Analysis ships with the lot it represents. The COA documents purity by HPLC, identity by mass spectrometry, residual solvents, and endotoxin testing. Every result is searchable by lot number, with no account required.

Why third-party
verification matters.
Independent verification is not a marketing line — it’s the only credible way to certify what’s in a research-grade vial. NZM does not operate its own analytical lab, and we never will. Every lot is tested by Janoshik Analytical, the reference laboratory used by EU research labs and contract research organizations.
The COA you receive lists the actual measured purity, identity confirmation by mass spectrometry, residual solvent screen, and endotoxin assay. The lot number on the vial label corresponds exactly to the lot tested. There is no average across batches, no representative sample — every lot is its own report.
For research designs where lot-to-lot consistency matters, this traceability is the whole game.
