About SLU-PP-332
SLU-PP-332 is a small molecule agonist of estrogen-related receptors (ERRα and ERRγ), developed at Washington University in St. Louis. It represents a new class of exercise mimetic compounds. SLU-PP-332 activates transcription factors that regulate mitochondrial biogenesis, oxidative metabolism, and endurance adaptations — essentially mimicking exercise at the molecular level. It is not a peptide but a synthetic organic compound with the molecular formula C₂₃H₂₂FN₃O₃.

Key Benefits
Exercise Mimetic Effects
SLU-PP-332 activates estrogen-related receptors (ERRα and ERRγ), transcription factors that regulate the same metabolic pathways activated by exercise. Users experience enhanced endurance without additional physical training.
Fat Oxidation & Metabolism
By activating ERR pathways, SLU-PP-332 promotes fatty acid oxidation and shifts energy metabolism toward lipid utilization, leading to reduced fat mass and improved metabolic profiles.
Endurance & Stamina
SLU-PP-332 directly enhances aerobic capacity through metabolic reprogramming, allowing you to push harder and longer during physical activity.
Mitochondrial Biogenesis
ERR activation by SLU-PP-332 upregulates genes involved in mitochondrial biogenesis and oxidative phosphorylation, increasing the number and efficiency of mitochondria within muscle cells.
Muscle Fiber Type Switching
SLU-PP-332 promotes a shift from fast-twitch (type II) to slow-twitch (type I) muscle fibers, which are more fatigue-resistant and rely on oxidative metabolism — a hallmark adaptation of endurance training.
How SLU-PP-332 Works
SLU-PP-332 works by directly activating estrogen-related receptors alpha and gamma (ERRα and ERRγ). These are orphan nuclear receptors — transcription factors that, despite their name, do not bind estrogen. Instead, they regulate a broad network of genes involved in energy metabolism, mitochondrial function, and oxidative phosphorylation.
When ERRα and ERRγ are activated, they drive the expression of genes responsible for mitochondrial biogenesis, fatty acid oxidation, and the Krebs cycle. This is the same transcriptional program that is normally activated by endurance exercise, which is why SLU-PP-332 is classified as an exercise mimetic.
SLU-PP-332 promotes a shift in muscle fiber composition from fast-twitch (glycolytic) to slow-twitch (oxidative) fibers, increases running endurance, and reduces fat mass — all without changes in physical activity levels. It was developed by scientists at Washington University in St. Louis.
Frequently Asked Questions
What is SLU-PP-332?
SLU-PP-332 is a small molecule agonist of estrogen-related receptors (ERRα and ERRγ). It was developed at Washington University in St. Louis (hence the SLU prefix). It mimics the molecular effects of exercise by activating transcription factors that regulate mitochondrial function and oxidative metabolism.
Is SLU-PP-332 a peptide?
No. Despite being sold alongside peptide products, SLU-PP-332 is a small organic molecule (molecular formula C₂₃H₂₂FN₃O₃), not a peptide. It is classified as a synthetic compound and ERR agonist.
Can SLU-PP-332 replace exercise?
SLU-PP-332 mimics certain molecular pathways activated by exercise, but it works best as a complement to physical activity. Exercise provides a wide range of benefits beyond metabolic effects, including cardiovascular, neurological, and musculoskeletal adaptations. Many users combine SLU-PP-332 with their existing training for amplified results.
How should I take SLU-PP-332?
Start with one 250mcg capsule daily. Many users take it in the morning with or without food. After assessing your tolerance, you can increase to 500mcg per day if desired. Consistency is key for best results.
How should SLU-PP-332 capsules be stored?
Store at room temperature in a cool, dry place away from direct sunlight. Refrigeration is not required but can extend shelf life. Keep the container tightly sealed.
