Epitalon

Khavinson tetrapeptide (Ala-Glu-Asp-Gly) that activates telomerase and regulates the pineal gland — the flagship longevity peptide.

Epitalon is the headline act of the longevity peptides. Each time a cell divides, the protective caps on its chromosomes (telomeres) get a little shorter — run them out and the cell ages and stops dividing. Epitalon switches on telomerase, the enzyme that rebuilds those caps, and it also restores the pineal gland's melatonin rhythm, which flattens with age. The Russian Khavinson cohorts that ran it periodically over years showed improved aging biomarkers and better sleep. It's taken as a short course once or twice a year, not continuously.
