Epitalon – Research-Grade Tetrapeptide | 10 mg | Liquilabs Certified

Epitalon (also spelled Epithalon) is a synthetic tetrapeptide that has attracted significant research attention in the fields of telomere biology, pineal gland function, and longevity science. If you are sourcing Epitalon in the Netherlands, batch RGXEPI10-2602-01 from Regenorix carries the most complete analytical profile available in this market.

What is Epitalon?

Epitalon (Ala-Glu-Asp-Gly) is a four-amino-acid synthetic peptide based on a naturally occurring sequence isolated from the pineal gland. It has been studied extensively in gerontological and longevity-focused research environments, with particular interest in its interaction with telomerase activity, circadian rhythm regulation, and age-related biomarker modulation in preclinical models.

Research applications include:

• Telomerase enzyme activation studies in cell models
• Pineal gland function and melatonin pathway research
• Circadian rhythm regulation models
• Antioxidant enzyme expression studies
• Age-associated biomarker modulation in preclinical research
• Longevity and healthspan pathway studies
