Epithalon vs Dihexa
Side-by-side comparison of key properties, dosing, and research.
- Summary
- Epithalon is a synthetic tetrapeptide developed from the pineal gland extract Epithalamin by Russian scientist Dr. Vladimir Khavinson. It is one of the most researched longevity peptides, known for activating telomerase and extending telomere length — the molecular hallmarks of cellular aging.
- Dihexa is a potent experimental oligopeptide derived from angiotensin IV that dramatically enhances synaptogenesis. Preclinical research shows cognitive enhancement orders of magnitude more potent than BDNF — it is considered one of the most powerful nootropic compounds in research, but has very limited human safety data.
