Every batch of Epitalon is assayed in our own laboratory before it is released. Purity is measured by HPLC / Mass Spectrometry on the PDA 214 nm channel, reported as main-peak area against every integrated impurity peak. Molecular identity is confirmed by LC-MS across 2 monitored ion channels. The release specification is ≥98.0%. Across the 1 batch published here, measured purity was 99.41%.

Epitalon testing — common questions
- Is Epitalon third-party tested?
- Every batch of Epitalon is analysed in our own laboratory by HPLC / Mass Spectrometry, and all 1 published batch appear on this page with their full analytical results, chromatogram and mass spectrum. Independent third-party verification currently covers a selection of our range rather than every compound, and Epitalon is not among them at present.
- What purity is the current batch of Epitalon?
- Batch APL-EPI10-2608-01, the batch currently shipping, measured 99.41% by HPLC / Mass Spectrometry, tested 31 August 2026. The release specification is ≥98.0%. Across the 1 batch published here, measured purity was 99.41%.
- How do I find the certificate for the Epitalon vial I have?
- Each certificate reports one production batch, so match the batch number printed on your vial against the batch history on this page rather than against the compound in general. 1 batch is published: APL-EPI10-2608-01. If the batch you hold isn't listed, email [email protected] with the compound and batch number and we'll send the document.
- What is Epitalon tested for?
- Every batch is tested for Appearance, Identity (MS), Purity (HPLC), Peptide Content and Endotoxins. Each result is printed beside a fixed specification — ≥98.0% for purity, set as house policy rather than per batch, so a batch cannot pass by having its target moved. Molecular identity is confirmed by LC-MS across 2 monitored ion channels.
Epitalon identification
The registry identifiers printed on every Epitalon certificate. They are what lets the compound be checked against a public record independently of anything we assert about it.
