Anti-Aging & Longevity
Humanin
Summary
SLU-PP-332 is a small molecule exercise mimetic that activates estrogen-related receptors ERRalpha and ERRdelta (ERRa/d), transcription factors that drive oxidative metabolism programs. In animal studies it significantly enhanced endurance capacity and metabolic fitness without exercise, mimicking many of the cardiovascular and metabolic adaptations of aerobic training.
Humanin is a mitochondria-derived peptide (MDP) encoded in the 16S rRNA region of the mitochondrial genome. It protects neurons and other cells from apoptosis, improves insulin sensitivity, and declines significantly with age. HNG (S14G-Humanin) is a synthetic analog with 1000x greater potency.

Key Benefits
  • Significant enhancement of aerobic endurance capacity
  • Increases mitochondrial density and oxidative metabolism in muscle
  • Promotes beneficial shift toward oxidative muscle fiber phenotype
  • Improves cardiac efficiency and cardiovascular fitness markers
  • Potential for obesity, metabolic syndrome, and heart failure treatment
  • Exercise mimetic for populations unable to exercise (disability, frailty, disease)
  • Neuroprotection against amyloid-beta toxicity (Alzheimer's relevance)
  • Inhibits cellular apoptosis
  • Improves insulin sensitivity
  • Reduces cardiovascular risk markers
  • Anti-inflammatory effects
  • Correlates with longevity in centenarian studies
  • Protects against ischemic injury
  • Potential cancer cell apoptosis sensitization
Side Effects
  • Limited human data; all studies are preclinical (rodent)
  • Unknown cardiovascular effects with long-term or high-dose use in humans
  • Potential hormonal interactions via ERR pathway (ERRs modulate estrogen-related signaling)
  • Off-target effects not fully characterized
  • Injection site irritation
  • Limited human safety data available
