SLU-PP-332
Metabolic In trials Animal studies
Not a peptide. A small synthetic molecule that activates estrogen-related receptors (mainly ERRα), which control how muscle burns fuel. In mice it produced exercise-like changes: more fat burning, better endurance and less weight gain, without a change in food intake.
Evidence at a glance
- Evidence
- Animal studies — Not yet studied in people
- Status
- Reached clinical trials
- Dosing
- No human study has set a dose
Mouse data from one lab. Nothing in humans, and ERR agonism affects many tissues.
What studies report
- Exercise-like changes in mice: more fat burning, better endurance, less weight gain without eating less
- Improved metabolic markers in obese mice
How it works
Activates estrogen-related receptors, mainly ERRα, which govern how muscle selects and burns fuel. Switching them on reproduces much of the gene expression pattern that exercise produces.
Where it acts
PancreasThe library groups this compound under Metabolic. The diagram shows that target, not every tissue it reaches.

In practice Unapproved use
- Marketed as 'exercise in a pill', which drove rapid uptake
- Circulating in both injectable and oral tablet forms
Science hasn't caught up: Consumer uptake is running well ahead of a mouse-only evidence base.
Reported real-world use, not evidence and not a recommendation.
Status: Mouse and cell research only. No human trials published.
