Humanin

Humanin is a naturally occurring mitochondrial-derived peptide (MDP) with potent neuroprotective and cytoprotective properties. Researchers study it for its role in cellular survival, longevity, and protection against age-related and neurodegenerative diseases.

In the literature, Humanin appears most often in work focused on neuroprotection, longevity and brain health. Studies in this area tend to look at mechanisms and observed effects in laboratory and preclinical settings rather than outcomes in people, so the picture is best read as a map of where researchers have been curious — not as evidence of any benefit.

Because it is catalogued here under powder peptides, Humanin also shows up in discussions of cellular repair. Coverage across those topics varies widely in quality and depth, and much of it is early-stage. Reading the underlying research directly is the only way to judge how strong any particular finding is.
