Storage & handling: Store at 2–8 °C (≤ –20 °C long-term), away from light. Ships at ambient temperature.
How we test
Certificates are issued by independent labs. Identity and purity are measured by LC-MS; endotoxin, where listed, by a LAL screen. The latest report for this option: Identity, purity & endotoxin tested, lot 395518, tested 30 Mar 2026.
How to read your COA
Start with the lot number on the report. Identity confirms by mass spectrometry that the molecule is the one on the label. Purity is the share of the sample that is the target peptide, measured by LC-MS. Endotoxin, where tested, is screened by LAL and must sit below 0.5 EU/mL. The lab name and test date show who ran it and when.

Researchers often ask
Is Epithalon for human use?
No. Epithalon is sold for laboratory research only. It is not for human or veterinary use, and it is not a drug, food or cosmetic.
How do I find the lab report?
Use View COAs on the product page, or search the COA library by compound name. The summary is public; the signed PDF reports are available to signed-in researchers.
Why is purity measured by LC-MS?
LC-MS separates the sample and identifies each component by its mass, so one run confirms identity and measures purity.
