Oral Epithalon capsules provide a convenient alternative to injectable Epithalon for telomerase activation and longevity support. Epithalon (Epitalon) is a synthetic tetrapeptide (Ala-Glu-Asp-Gly) developed by the St. Petersburg Institute of Bioregulation and Gerontology under the direction of Vladimir Khavinson, who has published extensively on its anti-aging properties over several decades. The compound is derived from epithalamin, a natural polypeptide extract from the pineal gland, and has been studied in both animal models and human subjects in Russia. Preclinical studies have demonstrated telomere elongation, telomerase activation, and lifespan extension in multiple animal models. Human studies conducted by Khavinson and colleagues reported improvements in melatonin production, circadian rhythm regulation, and various biomarkers of aging. While injectable forms have higher bioavailability, oral Epithalon still provides meaningful benefits through intestinal absorption, making it a convenient option for long-term longevity protocols.
