Vesugen

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.
