What's SLU PP-332?
SLU PP-332 250mcg is an oral synthetic ERRα agonist discovered at Saint Louis University. Unlike hormones or stimulants, it potently activates ERRα, a transcriptional master regulator of cellular energy metabolism in tissues like muscle and heart. By binding ERRα, it upregulates programs for mitochondrial biogenesis, fatty acid oxidation, and oxidative phosphorylation. A capsule formulation is the likely delivery method for human use.
SLU PP-332 250mcg are our company (Lymall Bpanda) best selling Weight loss capsules in the market. We sell to the USA, UK, and EU every day. Our machines operate year-round without interruption.
According to one of our AU clients' feedback, it is so damn popular.We support OEM formulation, making & printing labels, and even the color and size of the bottles can be customized.

The benefit of SLU PP-332 capsules
1. Potent Activation of Cellular Energy and Metabolism.
SLU PP-332 250mcg works by powerfully activating a group of proteins called ERRα, ERRβ, and ERRγ (Estrogen-Related Receptors).This activation "flips a switch" in cells, pushing them to burn more energy.
2.Potential for Weight Management & Metabolic Health
- Increase metabolic rate (the body's calorie burn).
- Improve glucose handling and insulin sensitivity, which are key issues in type 2 diabetes.
- Reduce fat accumulation in the liver (addressing non-alcoholic fatty liver disease).
3. Enhanced Physical Endurance
Treated mice could run significantly longer and farther before exhaustion. This is likely due to muscles becoming more efficient at using energy.
4. Neuroprotective Potential
Protect neurons from damage.
Help in conditions like Alzheimer's disease, Parkinson's disease and multiple sclerosis.
Support cognitive function by improving the energy supply to brain cells.
5. Possible Heart Muscle Protection
Some research indicates SLU PP-332 might help protect heart muscle cells during stress, such as from heart attacks or heart failure models in animals.

Production Process
This product adopts an industrial-grade standardized production process, operating in a cGMP cleanroom. The entire process is monitored in real time by a PLC automated control system. Key process parameters (temperature, time, pressure, solvent ratio, etc.) are executed according to SOP standard operating procedures to ensure the uniformity, stability, and traceability of each batch of products.
1. Plant Extraction Process
- Pretreatment: Dry-clean & pulverize to 60-120 mesh.
- Extraction: Ethanol soak 1-2h → ultrasonic (15-18KHz / 50-70℃).
- Collection: Vacuum-delivered to filtration.
- Optional: water/acid/CO₂ extraction. Post-extraction: synthesis & purification.
2. Filtration/Concentration/Drying
- Filtration: 200-300 mesh → precision filtration.
- Concentration: 50-70℃ vacuum to ~1/10 volume.
- Drying: Spray drying (160-200℃/80-100℃) or freeze drying (-40~-50℃, 3-5h).
3. Mixing/Standardization
- Mixing: Powder + excipients in 3D mixer, 30-60min.
- Standardization: HPLC assay → adjust to 250mcg/unit.
