Epithalon (also known as Epitalon) is a synthetic tetrapeptide that has gained attention in longevity and cellular aging research. Originally developed based on the naturally occurring peptide epithalamin, Epithalon is studied for its potential role in regulating biological aging processes, particularly those related to cellular repair, telomere maintenance, and gene expression. Researchers have explored how this peptide may influence cellular signaling pathways associated with long-term tissue health and metabolic balance.
