Humanin

A 24-amino-acid mitochondrial-derived peptide encoded in mitochondrial DNA that exerts cytoprotective and neuroprotective effects, in part through interaction with the insulin/IGF-1 signaling pathway.

Mechanism of action from published research — how the molecule behaves, not a claim about any product or any human-use effect.

Studied for neurodegenerative disease, cardiovascular protection, and lifespan regulation.

• Longevity & anti-agingStudied in aging, cellular-senescence, and mitochondrial-function research.

Preclinical / animal research — lifespan effects shown in C. elegans and rodent models; human data are limited to observational studies correlating declining blood levels with age and disease.

Where the science stands — an approved drug is not the same as the research-grade material a vendor sells, which is unregulated regardless.

• Independent purity. Look for a third-party COA (Janoshik or MZ) showing a measured purity — not just a number the vendor typed.
• Batch match. The strongest evidence is a certificate for the exact batch you’ll receive, attributed to this vendor — check the cross-verification on the listing.
• Vendor reputation. See how the vendor is talked about in the community before trusting a new name.

Research context only — VialGrade never gives dosing, medical, or human-use guidance.
