SLU-PP-332 · The "exercise mimetic", in mice only
An experimental ERR agonist with mouse data and a lot of headlines.
Medically reviewed by Bernard Garcia, MD
What it is
SLU-PP-332 is an experimental small molecule (not a peptide) that activates estrogen-related receptors (ERR), which regulate mitochondrial and muscle metabolism. Mouse studies published in 2023 reported increased endurance and reduced fat mass, generating "exercise in a pill" headlines.
No human trials exist. Products sold online are unregulated copies of a research compound.
How it works
ERR activation is proposed to mimic some metabolic adaptations to exercise. The published work is in rodents, over short periods, with no human safety data.
Research status
| Research area | Status |
|---|---|
| Endurance / fat mass (mouse models) | Preclinical |
| Mitochondrial metabolism | Preclinical |
| Human clinical trials | None |
| Regulatory status (US FDA) | Not an FDA-approved drug |
Status reflects published research context only and is not a statement of safety, efficacy, or suitability for any person.
Is it legal?
In the United States this compound is not an FDA-approved drug for any use. It is not lawfully sold for human use as a "research chemical", and whether a licensed provider can consider it depends on federal compounding rules and state law, both of which change. This is a general note, not legal advice.
Frequently asked questions
Is it a peptide?
No. It is a small molecule; it is included because it is sold and discussed alongside peptides.
Does it replace exercise?
No human study has tested that. The mouse findings are interesting biology, not a product.
Can a provider prescribe it?
No. It is an unapproved research compound with no human data.
