SLU-PP-332
Cognitive Enhancement
Semax
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.
Semax is a synthetic heptapeptide derived from ACTH developed in Russia. It is a potent nootropic that enhances memory, focus, and provides neuroprotection. Approved in Russia for cognitive disorders, stroke recovery, and traumatic brain injury.
Half-Life

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)
  • Enhances memory and learning
  • Improves focus and concentration
  • Increases mental energy and motivation
  • Provides neuroprotection via BDNF and NGF upregulation
  • Reduces cognitive decline
  • May alleviate ADHD symptoms
  • Supports recovery from brain injury and stroke
  • Fast-acting — effects within 30–60 minutes
  • Approved in Russia for cognitive disorders and stroke recovery
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
  • Headache (rare, often from higher doses)
  • Anxiety or overstimulation at high doses
  • Sleep disruption if dosed too late
  • Irritability (uncommon)
