EP10-0502
Report published
Epitalon is a single-compound research material labelled 10 mg per vial and supplied as lyophilised powder. When reviewing its documentation, compare the catalogue name, the report's analyte name and the exact batch identifier. The product label and analytical amount serve different purposes; read both alongside the original manufacturing-partner report. For research use only.
Batch EP10-0502 is linked to Janoshik task 156977, commissioned by the manufacturing partner. The catalogue records the submitted-sample name as Epi 10mg and the test date as 21 May 2026. The amount-result analyte is recorded as Epithalon, while the catalogue product name is Epitalon; both names are preserved for document matching.
The batch record lists 11.22 mg for that analyte and 99.534% purity. The 10 mg label remains the labelled strength. Identity is recorded as confirmed by the assay, rather than as an additional standalone identity report.
The recorded report scope is amount and purity. It does not provide sterility, endotoxin or heavy-metals results. Use EP10-0502 and the original report when checking documentation; the findings should not be transferred to another batch solely because its product name matches.
For help interpreting the results, read our guide to reading a certificate of analysis (COA). For supplier checks, ordering and delivery, see our guide to research peptide suppliers in Bali.
Store lyophilised vial at −20°C in a dry environment. Keep the vial sealed until required and minimise exposure to light and moisture. Handling should follow standard laboratory practice for research materials.
