Dosage overview
| Typical dose | No established human dose |
| Frequency | Experimental only |
Dosing notes
Humanin is primarily studied in preclinical settings (cell culture and animal models). A synthetic analog called HNG (S14G-humanin) has shown enhanced potency in research. No human clinical trials have established dosing protocols. Circulating humanin levels decline with age, which has prompted interest in supplementation, but delivery methods and dosing remain entirely experimental. Intranasal and subcutaneous routes have been used in animal studies.
Important safety information
Dosage ranges listed above are based on available research data and reported protocols. Individual dosing should be determined by a qualified healthcare provider based on your specific health profile, goals, and response to treatment.
- Start at the lowest effective dose and titrate up gradually
- Monitor for side effects, especially during dose increases
- Do not exceed researched dose ranges without medical supervision
- This is a research compound — human dosing guidelines are not FDA-established
