Identity
Unlike most of the compounds on this list, SLU-PP-332 is not a peptide at all, it is a small molecule built to switch on a family of cell receptors called estrogen-related receptors, or ERRs. Researchers at Saint Louis University designed it to copy some of what happens inside muscle cells during a workout, without the workout itself. It is a recent discovery, and no human being has ever received it in a published study.
SLU-PP-332 is a laboratory reference material. SBz Industries sells it for laboratory research.
Research
In plain terms, with a link to every study. The most useful thing to notice is what each study was done in.
Every published study on SLU-PP-332 so far has been done in mouse models or in cells growing in a lab dish. Researchers have looked at a muscle cell line, mice on standard and high-fat diets, and mice bred to carry extra body fat. No human trial has been published.
mice2023
This is the paper that first described SLU-PP-332. Researchers tested it in a skeletal muscle cell line, where it raised cell respiration and mitochondrial activity, then gave it to mice and measured how long the mice could run and which muscle fiber types increased.
Synthetic ERRα/β/γ Agonist Induces an ERRα-Dependent Acute Aerobic Exercise Response and Enhances Exercise Capacity.
Billon and colleagues, ACS Chemical Biology
mice2024
Mice fed a high-fat diet, and a separate strain of mice that naturally carry extra body fat, were given SLU-PP-332, and researchers measured energy use, fat-burning, and body fat over the following weeks. Treated mice used more energy, burned more fat for fuel, and gained less body fat than untreated mice.
A Synthetic ERR Agonist Alleviates Metabolic Syndrome.
Billon and colleagues, Journal of Pharmacology and Experimental Therapeutics
Each study links to its record on PubMed, the US National Library of Medicine database. Checked 25 September 2026.
Handling
Give the vial twenty minutes on the bench before opening it, so water does not condense onto the powder.
Slowly, down the inside wall of the vial, never straight onto the powder.
Leave it alone until it clears. Do not shake it. Shaking damages the peptide.
Once mixed, it breaks down much faster than the dry powder. Keep it cold and dark.
Documentation
An independent lab tests every compound we sell. It confirms the compound is what the label says and measures purity by HPLC.
The latest certificate is on the product page, so you can read the result before you order.

No published study has given SLU-PP-332 to a person. All research to date is in mice and in cells growing in a lab dish.
It targets estrogen-related receptors, the same receptors that become more active in muscle during aerobic exercise, which is why researchers call it an exercise mimetic in mouse studies.
SLU-PP-332 ships as a freeze-dried powder. Mix it with bacteriostatic water, added slowly down the inside wall of the vial, and let it dissolve without shaking. The researcher decides the working concentration, not us, and we publish no protocols.
Store as stated on the product page and the certificate of analysis. Vials ship in plain outer packaging with no product name on the outside.
