Epithalon (also known as Epitalon or Epithalamin) is a synthetic tetrapeptide utilized in laboratory environments to study cellular aging pathways, telomerase-related mechanisms, and peptide–gene interactions. It is modeled after a naturally occurring peptide isolated from the pineal gland, making it useful for scientific investigations focused on cell regulation, chromosomal stability, and molecular signaling processes.

Researchers typically employ Epithalon in in vitro assays, cell culture models, and biochemical pathway studies to observe how short-chain peptides may influence gene expression patterns and intracellular signaling events under controlled conditions.

Epithalon is not intended for human or veterinary use. It is provided exclusively for laboratory research, analytical testing, and educational investigation, with no claims regarding biological effects or suitability for consumption.
