SLU-PP-332, simplified.
Also called "Exercise mimetic", ERR agonist (not a peptide)
Early researchA lab compound nicknamed an "exercise pill". In mice it switched on some of the same muscle genes as exercise. It has never been tested in people.

What is it?
SLU-PP-332 activates proteins called ERRs that help muscles switch on endurance programs during exercise. Researchers hoped it could mimic some benefits of exercise for people who cannot work out.
What studies show
- In animalsMice on it ran about 70% longer and farther than untreated mice.
- In animalsObese mice gained less fat and had better blood sugar control.
What we don’t know yet
- Everything about its effects and safety in people. No human studies exist.
Side effects and cautions
- No human safety data at all.
- Online products are not quality-controlled.
Is it legal?
Not FDA-approved for human use.
