In Plain English:
Vesugen is a three-amino-acid chain — lysine, glutamic acid, and aspartic acid — modelled on a peptide sequence found in vascular wall proteins. Small Russian clinical studies report improvements in arterial blood flow, reductions in erectile dysfunction linked to atherosclerosis, and benefits in lower-limb arterial insufficiency in elderly patients. In cell and mouse experiments, it restores the Ki-67 proliferation marker in aged endothelial cells, normalises gap-junction proteins (connexins), upregulates SIRT1, and — at a separate neurological level — recovers mushroom-spine density in an Alzheimer's mouse model. Western replication is absent; all human clinical data originates from a single Russian research group.

Origin
Identified and synthesised by Vladimir Kh. Khavinson at the St. Petersburg Institute of Bioregulation and Gerontology, Russia. Derived from the amino-acid sequence of bovine vascular-wall proteins; later produced synthetically from plant-derived amino acids. Introduced into Russian clinical practice as a food-supplement cytogen (peptide complex AC-2) alongside the full Khavinson bioregulator series.
Mechanism
Binds the promoter region of the MKI67 gene (molecular docking confirmed) and stimulates Ki-67 protein synthesis, counteracting the age-related decline in endothelial cell proliferation. Normalises endothelin-1 (EDN1) expression in atherosclerotic aortic endothelium. Restores connexin gap-junction proteins (Cx37, Cx40, Cx43), maintaining endothelial cell-to-cell communication. Upregulates SIRT1, linking it to calorie-restriction-like vasoprotective phenotypes. In neural tissue, binds promoter regions of CASP3, GAP43, APOE, SOD2, PPARA, and PPARG; increases mushroom-spine density in 5xFAD Alzheimer's mice (sex-specific, pronounced in males). Stimulates proliferation and inhibits apoptosis in organotypic neuroimmunoendocrine cultures (Ki-67 up, p53 down). May promote nitric-oxide-dependent relaxation and prostaglandin-mediated vasorelaxation.
Outcome
Ki-67 expression in aged vascular endothelial cultures (in vitro), endothelin-1 levels (atherosclerotic cell culture), connexin expression (Cx37/Cx40/Cx43), SIRT1 expression, penile arterial blood flow (duplex Doppler, n=41 RCT), International Index of Erectile Function score, lower-limb blood flow (clinical + Doppler, n=41), mushroom-spine density in 5xFAD mice (in vivo), memory/attention scores in elderly with CNS disorders (clinical observation), mesenchymal stem-cell proliferation markers.
