Vesugen
Also known as: Lys-Glu-Asp tripeptide
Vesugen (Lys-Glu-Asp) is proposed to enter the cell nucleus and bind DNA and histones in gene promoter regions, modulating expression of vascular, senescence and neurogenesis genes rather than acting as a classical receptor agonist.
- Drug class
- Short-peptide bioregulator (synthetic tripeptide)
- Primary targets
- Gene promoter regions / DNA, Histone proteins, Endothelin-1 expression, Connexins, Sirtuin-1 (SIRT1)
- Dose reference
- No approved or established human dose; research-only. Figures cited for Russian supplement courses or reconstituted research vials are not dosing recommendations.
- Half-life
- No published human pharmacokinetic data; as an ultrashort tripeptide it is expected to clear from plasma within minutes.
- Developer / origin
- St. Petersburg Institute of Bioregulation and Gerontology (V. Khavinson and colleagues)
- Reference year
- 2003
- Evidence score
- 2/5 - Preclinical with very limited human evidence
Preclinical with very limited human evidence
Vesugen (KED) has reproducible in vitro and rodent gene-expression signals from the Khavinson research network, but human data are minimal, uncontrolled, single-network, and unreplicated, with no regulatory approval and no robust pharmacokinetic dataset.
Mostly animal, ex vivo, cell, or indirect evidence.
Evidence basis
- In vitro studies report KED alters senescence (p16, p21) and neurogenesis (NES, GAP43) gene expression and restores neuronal spine counts in Alzheimer's-disease cell models
- A 2021 Khavinson-group systematic review aggregates cardiovascular, neuroprotective and geroprotective claims, all mechanistic rather than outcome-based
- Human evidence is limited to a reported improvement in memory and attention in elderly subjects, without transparent randomized controlled trial design
- No FDA/EMA review, no independent Western trial, and no published human pharmacokinetic profile

How to read this entry
Dose references and half-life values are pulled from trial protocols, labels, reviews, or published summaries where available. They are context for research and comparison, not a personal dosing recommendation.
Status matters: approved drugs have regulated indications; investigational compounds are still being studied; research-only peptides do not have established human dosing, safety, or efficacy for consumer use.

GHK-Cu
Copper tripeptide-1
Naturally occurring tripeptide bound to copper. Studied for wound healing, skin remodeling and gene-expression effects related to tissue repair.
Humanin
HN, MTRNR2
Humanin is a 24-amino-acid mitochondrial-derived peptide that limits stress-induced apoptosis by binding pro-apoptotic proteins (BAX, Bid/Bim) and IGFBP-3 intracellularly and by signaling extracellularly through FPR2/FPRL1 and the CNTFR/WSX-1/gp130 complex to activate JAK2/STAT3, ERK1/2 and AKT survival pathways.
Thymalin
thymus polypeptide fraction
Thymalin is a calf-thymus polypeptide complex proposed to act as an immunomodulator that promotes T-lymphocyte differentiation and maturation and normalizes cytokine and immune-cell balance, though its precise molecular receptor or target remains undefined.
Thymogen
Glutamyl-Tryptophan, gamma-glutamyl-tryptophan
Thymogen is a synthetic L-glutamyl-L-tryptophan dipeptide that acts as a thymic-peptide immunomodulator, promoting T-lymphocyte differentiation and peptide-MHC recognition, shifting IL-2 and interferon cytokine output, and enhancing neutrophil chemotaxis and phagocytosis.
