Epithalon (also written as Epitalon or Epithalone) is a synthetic tetrapeptide — a chain of just four amino acids (Ala-Glu-Asp-Gly) — derived from a naturally occurring peptide called Epithalamin, which is produced by the pineal gland. It has become one of the most studied peptides in the field of longevity and ageing research, primarily for its potential role in telomerase activation.
What Are Telomeres?
Telomeres are protective caps at the ends of chromosomes, often compared to the plastic tips on shoelaces. Each time a cell divides, its telomeres shorten slightly. When telomeres become critically short, the cell can no longer divide and enters a state of senescence — it effectively stops functioning. This progressive shortening is considered one of the hallmarks of biological ageing.
Epithalon and Telomerase
Telomerase is the enzyme responsible for maintaining telomere length. Most adult somatic cells express very low levels of telomerase, which is why telomeres shorten over time. Preclinical research on Epithalon has focused on its ability to stimulate telomerase activity, potentially slowing or partially reversing telomere shortening in studied cell lines.
Key findings from published research include increased telomerase activity in human somatic cells exposed to Epithalon, as well as observed improvements in cell proliferative potential in vitro.
Pineal Gland and Melatonin Connection
Beyond telomerase research, Epithalon has been studied for its potential effects on the pineal gland itself. The pineal gland produces melatonin — the hormone that regulates circadian rhythm and sleep-wake cycles. Some preclinical studies have examined whether Epithalon may support melatonin production, particularly in aged animal models where pineal function naturally declines.
Related Longevity Peptides
Researchers studying ageing mechanisms often investigate Epithalon alongside complementary compounds:
- NAD+ — a coenzyme central to mitochondrial energy production and sirtuin activation, with levels that decline significantly with age
- MOTS-c — a mitochondrial-derived peptide being studied for its role in metabolic regulation and exercise mimetics
- SS-31 — a mitochondria-targeted peptide studied for its potential to improve mitochondrial membrane integrity
- Thymosin Alpha-1 — an immunomodulatory peptide studied for its role in immune system regulation
Reconstitution and Handling
Epithalon is supplied as a lyophilised powder and should be reconstituted with bacteriostatic water. Store at 2-8°C after reconstitution. Use our dosage calculator to determine volumes for your research protocol. Full purity data is available on our Certificates of Analysis page.
