About Vesugen+
About Vesugen
Vesugen is a synthetic tripeptide (Lys-Glu-Asp, also written KED; some papers use the code T-38) from Khavinson's short-peptide programme at the St Petersburg Institute of Bioregulation and Gerontology. Its developers describe it as a blood-vessel peptide. Most published work is in cells. In cultures of blood-vessel lining (endothelial) cells it raised levels of Ki-67, a marker of dividing cells (Khavinson et al., 2014), and in lab models of diseased artery lining it changed levels of endothelin-1 and sirtuin-1, proteins linked to vessel function and to the cell's response to DNA damage. In human stem cells grown in the lab it altered the activity of several genes linked to cell ageing (Ashapkin et al., 2020). A few rat studies used accelerated-ageing models. Human reports are small Russian studies in adults without described placebo groups, measuring markers such as biological age or blood flow in 32 to 41 people. Nearly all studies come from one research network and its partners, and none has been independently repeated. There are no published randomised placebo-controlled trials. How it behaves in the body and long-term safety are not known. Supplied for laboratory research use only.
Mechanism
No specific receptor has been identified for Vesugen. In cultured cells it changed levels of proteins such as Ki-67 (a marker of cell division) and endothelin-1, and computer docking by the developers suggests it could bind a DNA sequence in the switch region that controls the Ki-67 gene (Khavinson et al., 2014). The developers propose that it acts by changing gene activity, but this rests on cell culture and modelling, not on direct evidence in animals or people.
Research on Vesugen
Storage and handling
- Sealed and lyophilised, store at 2 to 8°C away from light and moisture. Minus 20°C for longer.
- Once reconstituted, keep refrigerated and avoid repeated freeze and thaw cycles.
- Bacteriostatic water is the usual diluent. The volume added sets the concentration in mg per mL.
- Vials carry a batch number for your laboratory records. Recent independent lab results are published in our COA Library.
FAQs
Can I order a single vial of Vesugen without a minimum order?+
Yes. The single-vial range exists precisely so a laboratory can take one vial of Vesugen rather than a full Factory Direct kit of 10. There is no minimum order quantity on this format.
How quickly does a Vesugen single vial ship in the UK?+
Single vials are held in our UK facility and posted the same day by Royal Mail Tracked 24 when paid by 3pm Monday to Friday. Orders placed after 3pm on Friday are posted on Monday morning.
How does the single vial differ from the factory-direct box?+
The compound and the manufacturing source are the same. The Factory Direct kit is a 10-vial pack and a lower per-vial cost, while the single vial is one vial from UK stock for small-scale or pilot work.
What purity is stated for Vesugen?+
≥99% manufacturer-stated purity. Buyers are encouraged to run independent third-party verification, and our testing directory lists laboratories that perform it.
Is this Vesugen vial for human use?+
No. Every Peptx product, including the single-vial range, is supplied strictly for laboratory research. It is not for human consumption, diagnosis, treatment or any clinical use.
What is Vesugen?+
Vesugen is a synthetic three-amino-acid peptide (Lys-Glu-Asp, or KED) from Khavinson's short-peptide programme in St Petersburg. Its developers describe it as a blood-vessel peptide. It is supplied here for laboratory research use only.
How does Vesugen work?+
No specific receptor has been identified. In cell cultures it changed levels of proteins linked to cell division and blood-vessel function, and modelling suggests it could bind DNA. Its developers propose that it acts by changing gene activity.
What has been studied?+
Mainly cultured cells, including blood-vessel lining cells and stem cells, plus a few rat studies. Human reports are small Russian studies without described placebo groups, and most work comes from one research network.
How is Vesugen stored?+
Store the freeze-dried powder sealed, cold and away from light, following standard laboratory peptide storage procedures. See the product specifications for detailed storage requirements.
