Testing

All Holon research compounds undergo double verification — manufacturer COA plus independent third-party testing through Janoshik — with public reports available for every batch. Our standard panel includes HPLC purity (verified 99%+), mass spectrometry identity confirmation, and endotoxin testing. Every batch is independently tested and tracked. You can access the Janoshik report for any product directly from its product page.

Storage

As a general guideline, lyophilized (freeze-dried) peptides should be stored in a cool, dry environment away from direct light — typically at -20°C for long-term storage, or at 2–8°C for shorter-term use. Once reconstituted, peptides should be kept refrigerated, used promptly or within 30 days, and where possible divided into single-use aliquots to minimize repeated freeze-thaw cycles, which can degrade peptide stability over time.
