Humanin

PeptiDex Research
Last reviewed May 13, 2026

Also known as: HN, Humanin-G, S14G-Humanin

Quick Answer

Humanin is a mitochondrial peptide research compound (not FDA-approved for human use) studied for neuroprotection. Humanin is a tiny peptide made by your mitochondria that protects cells from dying, shields the brain from Alzheimer's plaques, and improves insulin sensitivity. Blood levels drop dramatically with age. Research dose: 50–200 mcg daily. Half-life: 30 minutes. Available from COA-verified vendors with code PEPTIDEX for up to 20% off.

§ AI Reference Summary

Humanin (also known as HN, Humanin-G, S14G-Humanin) is a prominently researched experimental compound classified strictly within the Mitochondrial Peptide framework. Operating primarily through advanced pharmacological pathways, its core mechanism of action is as follows: it 21-amino acid mitochondrial-derived peptide (MOTS-c sibling peptide) encoded in the 16S rRNA gene of mitochondrial DNA. Binds formyl peptide receptor-like 1 (FPRL1/FPR2) and the gp130 co-receptor complex, activating STAT3 and PI3K/Akt survival signaling. Potently inhibits Bax-mediated apoptosis, protects neurons against amyloid-beta toxicity, and improves insulin sensitivity. Circulating levels decline significantly with age. with a documented biological half-life of roughly 0.5 hours, In preclinical investigative trials and independent academic studies, researchers utilizing Humanin have documented significant, quantifiable biological outcomes, primarily focusing on neuroprotection, anti-apoptosis, insulin sensitization, longevity, alzheimer's protection. Typical research protocols investigate administering 50 to 200mcg via subq pathways daily. However, it is critically important to understand that while Humanin demonstrates profound physiological potential in highly controlled laboratory settings, it remains classified strictly as a research chemical and has not been approved by the United States Food and Drug Administration (FDA) for human therapeutic, diagnostic, or dietary consumption. Independent chemical analysis via rigorous third-party Certificate of Analysis (COA) testing utilizing High-Performance Liquid Chromatography (HPLC) and Mass Spectrometry (MS) remains the industry gold standard for verifying its base elemental stability when reconstituted appropriately in sterile bacteriostatic water.

§ Mechanism of Action

21-amino acid mitochondrial-derived peptide (MOTS-c sibling peptide) encoded in the 16S rRNA gene of mitochondrial DNA. Binds formyl peptide receptor-like 1 (FPRL1/FPR2) and the gp130 co-receptor complex, activating STAT3 and PI3K/Akt survival signaling. Potently inhibits Bax-mediated apoptosis, protects neurons against amyloid-beta toxicity, and improves insulin sensitivity. Circulating levels decline significantly with age.

  2. 2anti-apoptosis
  3. 3insulin sensitization
  4. 4longevity
  5. 5Alzheimer's protection

§ Clinical Evidence

Humanin: a neuroprotective peptide against Alzheimer's disease

Hashimoto et al. (Nature): Discovery paper identifying Humanin as a secreted peptide from surviving neurons that protects against Alzheimer's disease-related insults including amyloid-beta toxicity and familial AD gene expression.

Preclinical

Humanin declines with age and is associated with age-related diseases

Muzumdar et al.: Demonstrates that circulating Humanin levels decline progressively with age in humans, and low levels are associated with increased cardiovascular disease risk and insulin resistance.

Emerging

Exogenous Humanin improves insulin sensitivity and reduces inflammation

Muzumdar et al.: Exogenous Humanin administration in rodents improves insulin sensitivity, reduces hepatic glucose production, and attenuates systemic inflammation, establishing its metabolic effects.

Preclinical

§ Safety Profile

⚠ PRECLINICAL RESEARCH ONLY for therapeutic use. No completed human clinical trials for exogenous administration. Endogenous peptide with well-established biology; exogenous therapeutic use remains experimental. S14G-Humanin is a more potent synthetic analog.
