Humanin

Humanin is a 21-amino acid mitochondrial-derived peptide studied for cytoprotective and anti-apoptotic effects, with community and off-label interest in neuroprotection, anti-aging, and metabolic health. The typical protocol reported by users is 500 mcg daily without a specified schedule, while clinician guidance cites 4 mg daily subcutaneously for 4–12 weeks. No side effects have been consistently reported in community discussions.
