Livagen is the tetrapeptide Lys-Glu-Asp-Ala, one of Vladimir Khavinson's short bioregulator peptides.
Livagen is a four-amino-acid peptide, Lys-Glu-Asp-Ala, written KEDA in one-letter code. It belongs to the same family of short bioregulator peptides as Epithalon and Cartalax, and we group it with them under Bioregulators. Vendors sell it research-use-only as a lyophilized powder, usually in 20 mg vials.
Most Livagen listings use the same 20 mg vial, so headline prices line up fairly well. The table above divides price plus a shipping estimate by the milligrams in each vial, which keeps multi-vial packs and smaller sizes honest.
Several bioregulators share the Lys-Glu-Asp start, including Vesugen (KED) and Testagen (KEDG), so the names and codes are easy to mix up. Confirm the compound on the label against the listing before ordering.
