Vilon is a synthetic Khavinson-type bioregulator tetrapeptide studied in immune and regenerative research. It is supplied as a high-purity white lyophilized powder at >=99% HPLC purity in sealed vials. Vilon is investigated for its role in supporting immune-cell function and tissue-regulatory processes, and is commonly applied in cell-based and preclinical studies. As a peptide bioregulator, it does not carry a single unified CAS number. The lyophilized presentation supports convenient reconstitution.. All batches undergo rigorous quality testing and batch-specific COA documentation can be provided on request. Store unopened vials sealed at 2-8 degree C, away from light and humidity; for longer preservation store at -20 degree C without repeated freeze-thaw cycles. Trial orders and bulk supply are supported, with OEM, private-label and secure neutral packaging available for global delivery. For research use only.
