Epithalon vs GHRP-6
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.
- GHRP-6 is the original synthetic GH-releasing peptide and a potent ghrelin receptor agonist. It produces strong GH pulses but is notorious for a significant hunger surge 30–45 minutes post-injection. This hunger side effect makes it less preferred than Ipamorelin or GHRP-2 for most protocols but can be useful in patients with appetite deficiency.
