SLU-PP-332: What It Is, How It Works & What the Research Shows
Overview
SLU-PP-332 is a synthetic small-molecule (non-peptide) agonist of estrogen-related receptors, mainly ERRα, which control mitochondrial energy production in muscle. It has been called an "exercise mimetic." In mice, it increased fatigue-resistant muscle fibers and running endurance. In obese mice, it raised energy expenditure and reduced fat mass and insulin resistance without changes in diet. Human studies have not been published.
Why researchers study it
Endurance
Increased running endurance in mice as an "exercise mimetic."
Fat loss
Reduced fat mass in obese mice without diet changes.
Mitochondria
Boosts mitochondrial energy production in muscle.
How it works
A small-molecule agonist studied for estrogen-related receptor signaling involved in oxidative metabolism. Exercise-like effects in animals do not establish human effects.
Adamantane & the blood–brain barrier
Chemically attaching an adamantane group to a peptide can increase its lipid (fat) solubility. Researchers hypothesize that this modification may help certain compounds cross the tightly regulated blood–brain barrier. The effect depends on the specific modified molecule; greater lipid solubility alone does not establish brain delivery or clinical benefit. This does not apply automatically to the unmodified peptide and is not a reconstitution additive.
What the research shows
- Estrogen-related receptor activation, energy expenditure, and exercise-like metabolic signaling have been studied in animals.
Typical protocol
Reconstitute a 5 mg vial with 1 mL bacteriostatic water for 5 mg/mL. Typical range: 2.5–20 mg 2–3x daily (am/mid/pm) · daily.
Common stacks
- SLU-PP-332 + MOTS-C — Two 'exercise mimetics' acting through ERR and AMPK pathways.
Potential benefits & side effects
Potential benefits
- Improved energy and exercise capacity
- Better insulin sensitivity and metabolic markers
- Support for mitochondrial function
- Potential fat-loss support (5-Amino-1MQ, AOD-9604, SLU-PP-332)
Side effects
- Injection-site irritation
- NAD+: flushing, chest tightness or nausea if pushed too fast
- Fatigue or restlessness early in a cycle
- GI discomfort with oral compounds
Lifestyle factors
- Exercise: these compounds work alongside, not instead of, regular training — especially zone 2 cardio.
- Sleep and circadian rhythm: keep a consistent sleep schedule.
- Nutrition: whole-food diet with adequate protein; avoid chronic overeating.
- Track bloodwork (glucose, lipids, liver markers) before and during longer cycles.
