Humanin

Humanin

Also known as: HN, HNG, S14G-Humanin, Mitochondrial-Derived Peptide

Overview

Key Facts

Primary Goal: Research and therapeutic applications of Humanin

Binds to IGFBP-3 to block BAX-mediated mitochondrial apoptosis. Activates STAT3 signaling pathway for cell survival.

Dosing Information

Half-Life

~30 minutes (native); enhanced analogs (HNG) have longer duration

Typical Dose

1–5 mg

Frequency

Once daily or 3-5 times per week

Cycle Length

4-8 weeks on, 4 weeks off

Administration Routes:
subcutaneousintravenous

Benefits

  • Potent neuroprotective effects against amyloid-beta toxicity
  • Cytoprotective against oxidative stress and apoptosis
  • Improved insulin sensitivity and metabolic regulation
  • Cardiovascular protection against ischemia-reperfusion injury
  • Supports mitochondrial function and cellular resilience

Side Effects

Injection site reactionsmild
Limited human safety datamild
Potential interaction with IGFBP-3 signalingmild

Mechanism of Action

1

Binds to IGFBP-3 to block BAX-mediated mitochondrial apoptosis

2

Activates STAT3 signaling pathway for cell survival

3

Interacts with formyl peptide receptors to reduce inflammation

4

Protects mitochondrial membrane integrity under stress conditions

Contraindications

Do not use this peptide if any of the following apply:

  • Active cancer (anti-apoptotic effects could theoretically promote tumour survival)
  • Pregnancy or breastfeeding
  • No established human safety profile

Research Summary

Preclinical

Discovered in 2001 by Bhshimoto et al. during research on Alzheimer's disease, humanin has since been shown to have broad cytoprotective effects. The S14G analog (HNG) is 1000x more potent than native humanin. Studies show that circulating humanin levels decline with age and correlate with Alzheimer's risk, mitochondrial dysfunction, and metabolic disease. Animal studies demonstrate protection against atherosclerosis, diabetes, and neurodegeneration. Epidemiological data from centenarian studies (led by Dr. Pinchas Cohen at USC) show elevated humanin levels in exceptionally long-lived individuals.
