02FAQ
Who performs Ethos Bio's testing?
Analysis is performed by MZ Biolabs, an independent analytical laboratory in Tucson, Arizona. Testing is separated from production, so identity and purity are confirmed by a third party rather than self-reported.
Is the Certificate of Analysis specific to my batch?
Yes. A batch-specific Certificate of Analysis corresponding to the exact production lot you receive ships with every order and is mirrored to your researcher account.
What does the five-point panel cover?
HPLC purity, mass-spectrometry identity, endotoxin (LAL), heavy metals (ICP-MS), and sterility or bioburden.
How do I verify a certificate?
Each certificate names the testing laboratory (MZ Biolabs) and references the specific production lot and analytical methods, so results can be traced from the vial back to the report.
