Six assays. One lab. Lot by lot.
Before a lot is listed, samples go to ILS, an ISO 17025-accredited laboratory in the United States. The results are printed on a certificate of analysis tied to that lot number.
What we test, and why each test exists.
Each assay answers one question about the material in the vial.
Purity
High-performance liquid chromatography separates the target compound from related impurities and reports how much of the sample is the compound itself.
On the COAIdentity
Liquid chromatography paired with mass spectrometry measures molecular mass and confirms the material is the compound named on the label.
On the COAContent
Measures how much material is in the vial and compares it with the labeled amount.
On the COAHeavy metals
Screens the sample for elemental contaminants.
On the COASterility
Checks the sample for microbial growth.
On the COAEndotoxin
Measures bacterial endotoxin in the sample.
On the COAMethod details, limits and units appear on each certificate exactly as ILS reports them.
Accredited, independent, in the US.
ISO 17025 is the international standard for testing and calibration laboratories. Accreditation means the lab's methods, equipment and staff competence are audited by an outside body. ILS is not owned by us and does not sell our products.
Testing questions
Who does the testing?
ILS, an ISO 17025-accredited laboratory in the United States. We don't test our own material for release.
How are lots tested?
Lots are sent to ILS for the six-assay panel. Each certificate is tied to one lot number and published in COA lookup when the lab releases it.
Where do I find a certificate?
Enter the lot number from your vial in COA lookup. Certificates appear there as the lab releases them.
