Vesugen vs PE-22-28
Side-by-side comparison of key properties, dosing, and research.
- Summary
- Vesugen is a tripeptide bioregulator (Lys-Glu-Asp) developed by Professor Vladimir Khavinson, tissue-specific for blood vessels and the vascular endothelium. It supports endothelial cell function, promotes vascular wall integrity, and is studied for atherosclerosis prevention, vascular aging, and cardiovascular health maintenance. It is one of the more broadly applicable Khavinson bioregulators given the ubiquity of vascular tissue.
- PE-22-28 is a synthetic analog of spadin derived from sortilin, designed to block TREK-1 potassium channels with rapid-onset antidepressant and neurogenic effects. It shows fast-acting depression relief (within 24 hours) and promotes hippocampal neurogenesis.
- Half-Life
- Short (minutes); sustained gene-regulatory effects
- Relatively short; CNS effects may persist due to neurogenic mechanisms
- Admin Route
- SubQ, Oral
- SubQ, Intranasal

- Key Benefits
- Supports vascular endothelial cell function and integrity
- May reduce endothelial inflammation and dysfunction
- Anti-aging effects on blood vessel walls
- Potential benefits in early atherosclerosis and vascular aging
- Supports nitric oxide-mediated vascular tone
