01Verification

Every lot of CJC-1295 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.

03FAQ

How is CJC-1295 tested?

Every Ethos Bio lot of CJC-1295 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 CJC-1295 meet?

CJC-1295 is released to a specification of ≥99% purity by reverse-phase HPLC, with identity confirmed by mass spectrometry against its molecular weight of 3,367.8 g/mol.

Does CJC-1295 come with a Certificate of Analysis?

Yes. A batch-specific Certificate of Analysis corresponding to the exact lot of CJC-1295 you receive ships with every order and is mirrored to your researcher account.
