Overview
SLU-PP-332 is an experimental small molecule that activates estrogen-related receptors. It is commonly described as an exercise mimetic because researchers studied muscle metabolism and endurance-related responses. The name does not mean it reproduces the full health benefits of exercise, and it does not identify an approved human medicine.
Community Use
PeptideDosages lists a SLU-PP-332 vial protocol, illustrating how preclinical tools enter wellness discussions. This remains a community source, not a validated adult regimen. Claims about easy endurance or fat loss should be checked against the original model, rather than inferred from the existence of a protocol page. Observed community protocol.
Doses, Durations & Cycles
Informal biohacking protocols and published regimens. Attributed website reports for education, not medical recommendations. Multiple publications document circulation; they do not establish a safe dose or validate a cycle.
| Route / formulation | Dose / reported phases | Frequency | Duration / break | Notes and source |
|---|---|---|---|---|
| Oral | Separate daily-dose patterns: ≤1.5 mg, 25 mg, 50 mg, or 100 mg | First three patterns: once daily; 100 mg pattern: once daily or divided twice daily | Community oral cycles: 8–12 weeks Break: 4 weeks | Published informal biohacking claim Peptide Dosing Protocols |
| Oral | 250–500 mcg | Twice daily | 10–12 weeks Break: 2 weeks | Published informal biohacking claim Rejuvenate You |
Important context: SLU-PP-332 is a synthetic small-molecule ERR agonist, not a peptide. The primary metabolic study administered it intraperitoneally to mice, not orally or SC to humans. Do not convert mouse amounts or treat microgram oral claims, milligram tablet claims, and SC claims as equivalent.
Additional sources: Billon et al., A Synthetic ERR Agonist Alleviates Metabolic Syndrome, JPET (2024). Consult the linked record for its exact formulation, population and methods.

No validated human wellness dose, loading phase, or cycling schedule is established in the cited research. Cell-culture concentrations and mouse exposures are different quantities from an outpatient dose. A chart should state that distinction explicitly and should not use body-size calculations to manufacture a human recommendation.
Research Findings
The 2023 primary paper studied receptor pharmacology, muscle-cell metabolism, and exercise-related outcomes in mice. It reported increased oxidative muscle characteristics and endurance-related effects in that experimental setting. The evidence is in vitro and animal work, not a human clinical trial. Preclinical exercise-mimetic research.
U.S. Approval & Access
No FDA-approved SLU-PP-332 medicine or human performance indication was identified. A research-tool listing cannot authorize clinical treatment. Interest in future metabolic drugs is compatible with choosing a legally available care plan today; a discussion should not imply that a research compound is routinely obtainable by prescription.
What It Does in the Body
Estrogen-related receptors regulate metabolic gene activity and are distinct from the estrogen receptors targeted in conventional hormone care. That naming distinction is important: SLU-PP-332 is not estrogen replacement. Changes in mitochondrial or oxidative activity offer a biological hypothesis, but are not proof of improved health in patients. Reliable human onset, peak benefit, and duration for the proposed exercise-mimetic use remain unknown.
Benefits & Reported Experiences
Mouse endurance findings do not establish easier exercise, safe weight reduction, or protection from chronic disease in people. A study can demonstrate a mechanism without answering practical questions about daily functioning, adherence, or sustained benefit. Such claims need human endpoints rather than a repeated exercise-in-a-pill slogan.
Side Effects & Risks
A validated human adverse-event profile is unavailable for a consumer regimen. Research that reports promising metabolic signals does not settle cardiac, reproductive, or long-term safety questions. Unknown risk should remain visible rather than being replaced by confidence derived from the short duration of an animal experiment.
Delivery Options
The routes and formulations in preclinical work are experimental details, not interchangeable consumer formats. Capsules and research vials cannot be compared solely by their labels. This profile does not provide preparation, injection, or self-titration instructions, because the cited evidence does not validate an outpatient pathway.
Product Quality & Storage
Distinguish an analytical tool compound from a finished clinical product. Questions about exact identity, exposure, and toxicology come before questions about the cheapest source. Purity testing cannot demonstrate that a material safely improves human performance or that it is equivalent to a future investigational formulation. Storage guidance for laboratory tools is not a substitute for a verified patient-product label; no consumer storage directions are invented here.
Combinations & Interactions
No human evidence here establishes an effective stack with 5-Amino-1MQ, mitochondrial peptides, or performance-enhancing hormones. Similar marketing goals do not demonstrate complementary biology or acceptable combined risk. Combining multiple unvalidated compounds also makes it harder to interpret which exposure produced a symptom or laboratory change.
Talking With Your Provider
If low stamina is the concern, explain the activities you struggle with and how long the problem has been present. A clinician can assess fatigue, exercise limitations, and appropriate options. The useful question is what will improve your function safely, not how to translate a mouse endurance experiment into a personal regimen.
