Vesugen
Also known as: Lys-Glu-Asp
Vesugen is a synthetic tripeptide, Lys-Glu-Asp (KED), from the Khavinson short-peptide 'bioregulator' series, positioned as a short-peptide analog of a bovine vascular-tissue polypeptide complex and claimed to be vasoprotective. Marketed on the Russian/Ukrainian grey market; not FDA-approved in the US; research-use only.

Prices observed from public storefronts (last 24h), normalized to $/mg. "Evidence" is Merit's 0–100 Merit Score, derived only from observable verification evidence (methodology on /about); "Purity" is the latest independent COA. Some buy links are affiliate links — Merit may earn a commission at no extra cost to you, and where a vendor offers one, the code shown gets you a discount at their checkout. Affiliate status never affects price data, ranking, or the Merit Score (full policy on /disclosure). Research use only.

Short Peptides Protect Fibroblast-Derived Induced Neurons from Age-Related Changes
Neurons become more vulnerable to stress factors with age, which leads to increased oxidative DNA damage, decreased activity of mitochondria and lysosomes, increased levels of p16, decreased LaminB1 proteins, and the depletion of the dendritic tree.

Transport of Biologically Active Ultrashort Peptides Using POT and LAT Carriers
Ultrashort peptides (USPs), consisting of 2-7 amino-acid residues, are a group of signaling molecules that regulate gene expression and protein synthesis under normal conditions in various diseases and ageing. USPs serve as a basis for the development of drugs with a targeted mechanism of action.

Neuroprotective Effects of Tripeptides-Epigenetic Regulators in Mouse Model of Alzheimer's Disease
KED and EDR peptides prevent dendritic spines loss in amyloid synaptotoxicity in in vitro model of Alzheimer's disease (AD). The objective of this paper was to study epigenetic mechanisms of EDR and KED peptides' neuroprotective effects on neuroplasticity and dendritic spine morphology in an AD mouse model.

[EFFECT OF SYNTHETIC PEPTIDES ON AGING OF PATIENTS WITH CHRONIC POLYMORBIDITY AND ORGANIC BRAIN SYNDROME OF THE CENTRAL NERVOUS SYSTEM IN REMISSION]
We've estimated the cellular and metabolic part of geroprophylactic effects of short synthetic tripeptides vesugen and pinealon for correction of the biological age. 32 people (18 men, 12 women) aged 41-83 years with polymorbidity and the organic brain syndrome in remission participated in the study.
