Cortagen is a synthetic Khavinson-type bioregulator studied in connective-tissue and organ-tissue research. It is supplied as a high-purity white lyophilized powder at >=99% HPLC purity in sealed vials. Cortagen is investigated in research on tissue regeneration and related regulatory processes, and is commonly applied in cell-based and preclinical studies. As a peptide bioregulator, it does not have a single formally assigned CAS number. The lyophilized presentation supports convenient reconstitution. The connective-tissue bioregulator peptide is studied in tendon, ligament and skin-repair research, and investigators evaluate its effects on tissue maintenance. It belongs to the tissue-specific peptide class. The product is lyophilized with purity records. The peptide is studied in connective-tissue repair models, with endpoints including collagen organization and tissue-remodeling markers. Its tissue-specific bioregulator design supports research into regeneration and aging, and the product is lyophilized with batch documentation for quality assurance. Quality control covers raw-material inspection, synthesis monitoring and final-product testing, and batch records can be shared with buyers upon request. Packaging is designed to preserve lyophilized stability during international transport, including cushioning and secure sealing.
