What is Epithalon?

Epithalon is a short peptide made of four amino acids: alanine (Ala), glutamic acid (Glu), aspartic acid (Asp), and glycine (Gly). It is classified as a synthetic peptide designed to mimic the activity of natural peptides produced in the pineal gland, an endocrine organ involved in regulating circadian rhythms and other biological processes.

Researchers have focused on Epithalon for its ability to influence cellular aging markers and potentially support DNA stability in laboratory models. It is widely used in preclinical studies examining cellular senescence and age-related changes at the molecular level.

Mechanism of Action: What Does Research Suggest?

While the full mechanism of Epithalon is still being explored, existing studies propose several potential pathways:

• Telomerase Activation: Epithalon may stimulate the enzyme telomerase, which is responsible for maintaining and elongating telomeres — protective caps at the ends of chromosomes that shorten with age. This effect has been observed in cellular studies, indicating possible roles in preserving chromosomal integrity.

• Gene Expression Regulation: Epithalon might influence genes involved in cell cycle regulation and apoptosis, supporting cellular homeostasis.

• Antioxidant Activity: Some research suggests Epithalon exhibits antioxidant properties that may help reduce oxidative stress in cells.

It is important to emphasize that these effects are primarily demonstrated in vitro and in animal models. Epithalon remains classified for research purposes only and is not approved for therapeutic use.

Handling and Storage in Research Settings

Epithalon is generally supplied as a lyophilized powder for research use. Proper handling is essential to maintain peptide stability:

• Store lyophilized Epithalon at –20°C or colder.

• Reconstitute with sterile bacteriostatic water or saline immediately before use.

• Avoid repeated freeze-thaw cycles to prevent degradation.

• Use freshly reconstituted solutions within recommended time frames.

Following these guidelines helps ensure reproducibility and reliability in experimental outcomes.
