SLU-PP-332 (SLU-PP-332 (ERR Agonist))
An experimental small-molecule "exercise mimetic" that activates estrogen-related receptors (ERRs). In animal studies it increased energy expenditure and endurance and reduced fat gain without changes in food intake or activity, by pushing cells toward fat-burning metabolism.
How it works
A pan-ERR (estrogen-related receptor alpha/beta/gamma) agonist. ERRs are master regulators of mitochondrial biogenesis and oxidative metabolism, so activation upregulates fat oxidation and the genetic program normally triggered by endurance exercise.
Key facts
- Molecular weight: ~426 Da (small molecule, not a peptide)
- Half-life: Not well characterized in humans
- Bioavailability: Studied via injection in animals; oral activity under investigation
- Storage: Store per supplier guidance; small molecules are often stable refrigerated and protected from light.
Dosing overview
- Typical dose: No established human dose
- Frequency: Unknown
- Duration: Unknown
- Route: Injection (preclinical)
Protocol notes
- Human dosing is not established. All current data are from rodent studies.
- Animal work used intraperitoneal injection over short study windows.
- Treat any human use as purely experimental with unknown safety.
Reported benefits
- Increases mitochondrial fat-burning (preclinical)
- Improved endurance in animals
- Reduced fat gain without appetite change (animals)
- Acts as an "exercise mimetic"
Possible side effects
- Human safety unknown
- No human side-effect data
- Potential cardiac/metabolic effects of broad ERR activation are unstudied in people
Research
- An ERR agonist that mimics aspects of exercise (2023): In mice, SLU-PP-332 boosted oxidative metabolism, increased running capacity, and limited diet-induced fat gain.
