How Is Semaglutide Tested?

Semaglutide is verified by independent third-party analysis — a five-point panel with a batch-specific Certificate of Analysis.

01Verification

Every lot of Semaglutide 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 Semaglutide tested?

Every Ethos Bio lot of Semaglutide 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 Semaglutide meet?

Semaglutide is released to a specification of ≥99% purity by reverse-phase HPLC, with identity confirmed by mass spectrometry against its molecular weight of 4,113.58 g/mol.

Does Semaglutide come with a Certificate of Analysis?

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