SLU-PP-332
Summary
Oxytocin is a 9-amino acid neuropeptide produced in the hypothalamus with diverse roles in social bonding, trust, stress reduction, and sexual function. Exogenous administration is used therapeutically to improve social cognition, reduce anxiety, and enhance intimacy.
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.
Half-Life
~3–5 minutes (IV); ~30–60 minutes (intranasal, CNS effects persist longer)
Not established in humans; rodent pharmacokinetics suggest hours
Admin Route
Intranasal, SubQ, IV
Oral (research), Subcutaneous (research)
Research
Typical Dose
20–40 IU
Not established for humans; rodent studies used ~100 mg/kg/day
Frequency
As needed (not daily long-term)
Once daily in rodent studies
Key Benefits
  • Enhances social bonding and trust
  • Reduces social anxiety and fear of rejection
  • Improves autism spectrum symptoms (social cognition)
  • Reduces cortisol and stress reactivity
  • Enhances sexual arousal and intimacy
  • Promotes maternal behavior and bonding
  • May improve depressive symptoms
  • Appetite suppression and metabolic effects
  • 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)
Side Effects
  • Mild uterine cramping (avoid in pregnancy)
  • Nasal irritation (intranasal)
  • Headache
  • Potential emotional over-attachment or jealousy amplification
  • +2 more
  • 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
