How Is Epitalon Tested?
Epitalon is verified by independent third-party analysis — a five-point panel with a batch-specific Certificate of Analysis.
01Verification
Every lot of Epitalon 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.
