What the studies show

No human dosing study of any kind, and therefore no safety data.

Animal studies, cell studies, or anecdotes only. This is where almost every viral peptide sits. Promising and proven are different words for a reason.

In context

Humanin is a small peptide encoded within mitochondrial DNA, discovered in 2001, with cell-protective effects in laboratory models of Alzheimer's, diabetes and cardiovascular stress. In people, blood levels of humanin fall with age and vary with disease — but that is observation of the humanin people already have, not a test of giving more. No controlled human trial has administered it. It is not approved anywhere.

Humanin is not approved. Legal status differs by country — see the regulation section or the jurisdiction pages.
