Janoshik Lab Verification FAQ
How does Janoshik conduct third-party blind testing?
Samples are submitted blind to avoid vendor bias. The analytical laboratory uses calibrated High-Performance Liquid Chromatography to determine total percentage purity and Mass Spectrometry to verify that the amino acid sequence exactly matches the theoretical molecular weight.
Can I verify a test result on Janoshik's official website?
Yes. Enter the Task Number and Verification Key displayed on any PrecisionsPeptides.com lab report PDF into janoshik.com/verify to independently confirm authenticity.
