How Is MOTS-c Tested?
MOTS-c is verified by independent third-party analysis — a five-point panel with a batch-specific Certificate of Analysis.
01Verification
Every lot of MOTS-c is analyzed by an independent third-party laboratory — MZ Biolabs, in Tucson, Arizona — before release. Testing is separate from production, so purity and identity are confirmed by a third party, not self-reported.
02The Five-Point Panel
| Purity | Reverse-phase HPLC · ≥99% |
| Identity | Mass spectrometry vs. 2,174.4 g/mol |
| Endotoxin | LAL assay |
| Heavy metals | ICP-MS |
| Sterility | Bioburden |
03FAQ
How is MOTS-c tested?
Every Ethos Bio lot of MOTS-c is analyzed by an independent third-party laboratory (MZ Biolabs, Arizona) on a five-point panel: reverse-phase HPLC purity, mass-spectrometry identity, endotoxin (LAL), heavy metals (ICP-MS), and sterility or bioburden.
What purity standard does MOTS-c meet?
MOTS-c is released to a specification of ≥99% purity by reverse-phase HPLC, with identity confirmed by mass spectrometry against its molecular weight of 2,174.4 g/mol.
Does MOTS-c come with a Certificate of Analysis?
Yes. A batch-specific Certificate of Analysis corresponding to the exact lot of MOTS-c you receive ships with every order and is mirrored to your researcher account.
