Lot-level analytical traceability for research-grade peptides
Abstract. Eternum supplies institutional-grade research peptides synthesized in the United States. Every released lot resolves to a reverse-phase HPLC chromatogram and a batch-specific Certificate of Analysis, made openly accessible before purchase rather than on request — documenting identity, purity, and provenance at the level of the individual lot.
Compounds are produced through US-based, cGMP-aligned synthesis and lyophilization, then sealed and stored under controlled conditions. Each lot is verified by reverse-phase HPLC at no less than 98% purity, with mass-spectrometry identity confirmation.
The resulting certificate — lot number, purity, identity, appearance, and storage — is published in the COA library and on every compound page, searchable by compound or lot, and readable before an order is placed.
