Humanin

Humanin is a 21‑amino‑acid mitochondrial‑derived peptide investigated for cytoprotective, anti‑apoptotic and longevity‑promoting activity, though it has no FDA‑approved use. In the community the most common regimen is 500 µg taken daily, with timing and cycling rarely specified; clinician‑guided protocols often use 4 mg subcutaneously each day for 4–12 weeks. The primary limitation is that the off‑label evidence base is thin, consisting largely of exploratory work without posted results, and no consistent side‑effect profile has emerged—reports of injection‑site reactions have not been a recurring theme.

Research Evidence

Evidence shape

Humanin currently holds a low evidence tier, as the existing literature is restricted to diagnostic and mechanistic studies rather than clinical interventions. While 24 published human studies exist, these focus on observational data and biological markers, leaving the peptide without any completed or registered clinical trials to support therapeutic use. The research remains entirely exploratory, with no data available to establish efficacy or safety for any specific medical indication.
