Quality is the core of Core Peptides. Our compounds are produced in the USA and analytically tested for identity and purity, with batch documentation available to researchers on request.
Compounds are checked by mass spectrometry to confirm the correct peptide is present.
High-performance liquid chromatography quantifies chromatographic purity to a ≥99% target.
Documentation for a specific batch is available to qualified researchers on request.
Lyophilized and stored under controlled conditions to preserve stability and consistency.
Every Core Peptides compound is backed by a third-party Certificate of Analysis documenting identity and purity by HPLC-UV and mass spectrometry (LC-MS). View the Certificate of Analysis for any compound below.
