Why we test
Research peptides vary in quality between manufacturers, and there's no way to verify purity by eye. Rather than ask you to take our word for it, we send batches to Janoshik Analytical — an independent lab with no commercial relationship to Nova Biolabs — for HPLC purity testing, and publish the results here.
Independent
Janoshik Analytical is a third-party lab, not affiliated with Nova Biolabs. They report what they find.
Batch-specific
Results are tied to a specific batch number, not a blanket claim about every unit we've ever sold.
Verifiable
Every result here links to the actual Certificate of Analysis, not just a headline percentage.

We're expanding batch testing across our range on an ongoing basis. If your batch number doesn't return a result yet, it may not have been tested at the time you ordered — contact us and we can confirm directly.
