What It Does

Humanin is a small peptide encoded within the mitochondrial genome (16S rRNA region), making it one of a class called mitochondrial-derived peptides (MDPs). It is cytoprotective across multiple tissues — brain, heart, vasculature, and metabolic organs. Humanin levels decline with age and are inversely correlated with Alzheimer's disease risk and metabolic dysfunction. It is considered a key longevity signaling molecule and a bridge between mitochondrial health and systemic aging.

Mechanism of Action

  1. Anti-apoptotic signaling: Activates JAK2/STAT3, PI3K/Akt, and MAPK pathways → inhibits Bax-mediated mitochondrial apoptosis
  2. Neuronal protection: Blocks amyloid-beta (Aβ) toxicity in neurons; reduces tau pathology markers
  3. Insulin sensitization: Activates FPRL1/FPR2 and gp130 receptors → improves insulin sensitivity and glucose metabolism
  4. Mitochondrial function: Supports mitochondrial membrane potential and reduces ROS production
  5. IGF-1 modulation: Interacts with IGFBP-3, modulating IGF-1 bioavailability and longevity signaling
  6. Systemic cytoprotection: Cardioprotective, hepatoprotective, and vasculoprotective effects reported

Dosing Protocols

Research-Informed Protocol

  • Dose: 2–4 mg/week SubQ (divided doses)
  • Frequency: 2–3x per week
  • Duration: Ongoing cycles with periodic assessment
  • Note: Human dosing extrapolated from rodent studies; clinical protocols not yet established
  • Source: The Peptides Bible, longevity research literature

Stacks Well With

  • TB-500 – systemic cytoprotection and tissue repair synergy
  • Melanotan II – complementary mitochondrial and metabolic signaling
  • MOTS-C – fellow mitochondrial-derived peptide; complementary longevity signaling
  • Epitalon – anti-aging and telomere support synergy
  • SS-31 – mitochondrial membrane protector; powerful MDP stack

Use Cases

  • Longevity and healthy aging (MDP decline reversal)
  • Neuroprotection (Alzheimer's risk reduction, neuronal survival)
  • Metabolic Health (insulin sensitization, glucose metabolism)
  • Cardiovascular Protection
  • Mitochondrial Health optimization
  • Cognitive Function maintenance

Contraindications & Safety

  • Active malignancy — anti-apoptotic signaling; theoretical concern
  • Limited human data — extrapolated from rodent studies; use cautiously
  • Drug interactions — JAK/STAT pathway involvement; caution with immunosuppressants
  • Common side effects: Not well characterized in humans; generally well-tolerated in animal models
  • Long-term safety profile in humans not established

Storage

  • Lyophilized: -20°C long-term; 2–8°C up to 3 months
  • Reconstituted: 2–8°C for 1–2 weeks; protect from light
  • Solvent: Sterile/bacteriostatic water
