Epitalon vs Humanin
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
Epitalon
Epitalon (Epithalon) is a synthetic tetrapeptide based on the natural peptide epithalamin, produced by the pineal gland. It is primarily studied for its effects on telomerase activation.
Full details →Humanin
Humanin is a mitochondrial-derived peptide with potent cytoprotective effects. Discovered in 2001, it has shown promise in protecting against age-related diseases including Alzheimer's, cardiovascular disease, and diabetes.

| Aspect | Epitalon | Humanin |
|---|---|---|
| Dose Range | 5 mg–10 mg | 100 mcg–500 mcg |
| Frequency | 1x daily | 1x daily |
| Cycle Length | 2–3 weeks | 4–8 weeks |
| Route | subcutaneous | subcutaneous |
| Mechanism | Stimulates telomerase production, which can lengthen telomeres on DNA strands. May also regulate melatonin production and circadian rhythms. | Binds to IGFBP-3 and BAX, inhibiting apoptosis. Activates STAT3 signaling and enhances cellular survival under stress. Protects mitochondrial function and reduces oxidative stress. |
| Typical Dosage | Typical protocols: 5-10mg daily for 10-20 days, repeated 2-3 times per year. | Research protocols vary widely. Studies have used doses from micrograms to milligrams depending on the analog and route. HNG (S14G-Humanin) is a more potent analog. |
| Administration | Subcutaneous or intramuscular injection. Usually administered in cycles rather than continuously. | Subcutaneous or intraperitoneal injection in research. Various analogs exist with different potencies and stabilities. |
| Side Effects | Generally well-tolerated. May affect sleep patterns initially. | Limited human data. Generally well-tolerated in animal studies. May affect glucose metabolism. |
