Where applicable, Royal Peptides research materials are supplied in lyophilized form. Lyophilization is a freeze-drying process used to remove moisture from material under controlled conditions.
Storage requirements may vary by compound, formulation and production lot. Refer to the product label and available product-specific documentation.
Packaging components may vary slightly between production lots. This can include vial closures, cap styles, label positioning and external packaging.
Vesugen 20mg (Lys-Glu-Asp) is a research-grade peptide bioregulator studied in vascular and endothelial tissue research.
For research use only. Not for human consumption.
Research noticeFor laboratory and research purposes only. Not intended for human consumption, diagnostic or therapeutic use, or administration to humans or animals.
Vesugen is a synthetic tripeptide bioregulator (Lys-Glu-Asp) from the Khavinson series, associated with the vascular wall. Royal Peptides supplies Vesugen as a high-purity, research-grade 20mg lyophilized vial. You can buy it as a single vial or as a 10-vial kit.
Vesugen has been studied in vascular endothelial cell models, the cells lining blood vessels, including work on markers of cellular ageing and proliferation in cultured vascular cells. It is used as a research tool for exploring how tissue-specific short peptides may affect gene expression in the vascular system.
Peptide bioregulators are ultra-short chains of 2 to 4 amino acids, first described by Prof. Vladimir Khavinson and colleagues. Each one is linked to a specific tissue, and they are studied for how they may interact with DNA and chromatin to affect gene expression. Vesugen is the vascular member of this family.

Store lyophilized Vesugen at -20°C for long-term stability, or at 2–8°C for short-term storage. Keep it away from light and moisture. Let the vial reach room temperature before opening. Handle it according to your lab’s standard procedures for research peptides.
Every batch of Vesugen is third-party tested by HPLC. A Certificate of Analysis (COA) is available for each lot so you can check identity and purity before use.
No. Vesugen is sold strictly for laboratory and in-vitro research.
Both contain the same 20mg vials from the same production standard. The kit has ten vials, typically from one batch, at $55 per vial instead of $65.
COAs are available on our Lab Reports page, or on request from our support team.
