Epitalon
Telomerase-stimulating tetrapeptide
About Crystagen
A Khavinson tripeptide bioregulator (EDP) derived from spleen extract, studied for immune-system aging research.
About Epitalon
Epitalon is a Khavinson tetrapeptide bioregulator (Ala-Glu-Asp-Gly / AEDG) modelled after the pineal-gland extract epithalamin in Russian gerontology research. It has been studied in animal and cell-culture models for telomerase activity, lifespan extension, and pineal-axis ageing parameters, and serves as the most widely cited member of the Khavinson short-peptide bioregulator panel alongside Pinealon, Cortagen, and the organ-targeted tetrapeptides. Sold by research-peptide vendors at 5–20 mg vial sizes for laboratory work; not approved by FDA, MHRA, Health Canada, or TGA for human use.
