Epithalon research overview

Epithalon (also spelled Epitalon) is a synthetic tetrapeptide studied in selected cell-culture systems.

Evidence boundary: published research does not establish the identity or performance of a separately supplied batch. The catalog product is supplied only for qualified in vitro laboratory research and is not for human or animal use.

What is Epithalon?

Published experiments have measured telomerase activity and telomere-associated endpoints in human cell cultures. These are laboratory observations, not demonstrations of lifespan extension in people.

Research category

Mitochondrial & cellular aging

Study models represented

Human fetal fibroblasts and selected human cell lines

Names in the literature

Epitalon; Ala-Glu-Asp-Gly

Primary boundary

Cell-culture endpoints do not demonstrate anti-aging or lifespan effects in humans.

What does the selected evidence support?

Cell-line behavior is context dependent and cannot establish clinical longevity, safety, or effectiveness.

Research literature and product documentation are different

A publication describes a study and its results. A batch-specific Certificate of Analysis documents characteristics of a supplied research material. One does not substitute for the other.
