What Epithalon is
Epithalon (Ala-Glu-Asp-Gly) was developed from studies of pineal gland extracts. It is among the shortest peptides studied in longevity research.
Claims about telomerase activation come mainly from one laboratory network. Independent replication is limited, which is why it is rated at the bottom of our scale despite its popularity.
What the research literature studies
- Telomerase activity and telomere length in cultured cells
- Cellular-senescence markers in vitro
- Short-peptide stability
Evidence rating: 1/5
Limited, preclinical or single-group. Single-group literature with limited independent replication. See our methodology for how levels are assigned.
- Limited independent replication of the key findings.
- Telomerase biology in vitro does not translate simply to organisms.
Regulatory status
Epithalon is not approved by the MHRA, EMA or FDA. Nordapep supplies it for in vitro laboratory research only.
