Doses studied in research Animal or lab studies only
What was given to people (or animals) in published studies and official labels, each linked to its source. This is not a recommendation: study products, purity and supervision differ from research-grade vials.
Animal studies: Studied only in mice (obese, aged and heart-failure models; e.g. 8 weeks of treatment in 21-month-old mice, PMID 37717940) and in cultured cells including human myoblasts (PMID 40692696); the PubMed abstracts found do not state the mg/kg doses used.
SLU-PP-332 is a small-molecule ERR agonist (not a peptide) with no human studies; no studied human dose exists. Doses in animal studies do not translate directly to people.
What the research says
SLU-PP-332 is an experimental ERR agonist studied only in mice and cell cultures, where it increased endurance and energy expenditure and reduced fat gain. No human trials exist; a 2026 systematic review states clinical trials are needed.
Key papers ✓ 5? 1
-
[Pharmacological Activation of ERRα/β/γ as an Exercise Mimetic: Potential Therapeutic Applications].Humans + animalsSystematic review
Systematic review of pan-ERR agonists (2020-2024, animal and cell studies only): exercise-like gene programs, less adiposity and better glucose control in rodents, but efficacy and safety in humans are untested.
Study details
- Studied
- Preclinical animal and cell studies (2020-2024) of pan-ERR agonists, especially SLU-PP-332 and SLU-PP-915
- Main outcome
- Effects on energy metabolism, muscle function, renal aging and metabolic syndrome
- Authors' conclusion
- Pharmacological activation of ERR alpha/beta/gamma is a promising exercise-mimetic strategy for metabolic disease, aging and muscle conditions; clinical trials are needed to confirm efficacy and safety in humans.
- Limitations
- Only preclinical studies; no human data.
-
Synthetic ERRα/β/γ Agonist Induces an ERRα-Dependent Acute Aerobic Exercise Response and Enhances Exercise Capacity.Humans + animalsIdentification and characterization of SLU-PP-332 in vitro and in vivo
SLU-PP-332 increased mitochondrial respiration in muscle cells and, in mice, increased oxidative type IIa fibres and running endurance via ERRalpha.
Study details
- Studied
- Skeletal muscle cell line and mice
- Main outcome
- Mitochondrial function, muscle fiber type, exercise endurance, exercise gene program
- Authors' conclusion
- SLU-PP-332, a pan-ERR agonist most potent at ERR alpha, increased type IIa oxidative fibers and exercise endurance in mice via ERR alpha, supporting the feasibility of ERR alpha-targeted exercise mimetics.
- Limitations
- Mouse and cell study.
-
A Synthetic ERR Agonist Alleviates Metabolic Syndrome.Animalssize not reportedSLU-PP-332 administration with metabolic assessments
In diet-induced obese and ob/ob mice, SLU-PP-332 raised energy expenditure and fat oxidation, reduced fat mass and improved insulin sensitivity.
Study details
- Studied
- Diet-induced obese and ob/ob mice
- Main outcome
- Energy expenditure, fatty acid oxidation, fat mass, insulin sensitivity
- Authors' conclusion
- SLU-PP-332 mimicked exercise benefits in mice (increased energy expenditure and fatty acid oxidation, decreased fat mass, improved insulin sensitivity); ERR activation may be effective for metabolic syndrome and obesity.
- Limitations
- Mouse models only.
-
Novel Pan-ERR Agonists Ameliorate Heart Failure Through Enhancing Cardiac Fatty Acid Metabolism and Mitochondrial Function.Animalssize not reported6-week pressure overloadSLU-PP-332 and SLU-PP-915 treatment with functional, multi-omics and genetic dependency studies
In a mouse pressure-overload heart failure model, SLU-PP-332 and SLU-PP-915 improved ejection fraction, reduced fibrosis and increased survival.
Study details
- Studied
- Mice with pressure overload-induced heart failure, plus in vitro cardiomyocyte work
- Main outcome
- Ejection fraction, fibrosis, survival, cardiac metabolism
- Authors' conclusion
- Both pan-ERR agonists improved ejection fraction, fibrosis and survival in pressure-overload heart failure without affecting hypertrophy, with ERR gamma the main mediator, supporting further development as heart failure therapeutics.
- Limitations
- Mouse model; no human data.
-
Estrogen-Related Receptor Agonism Reverses Mitochondrial Dysfunction and Inflammation in the Aging Kidney.Animalssize not reported8 weeks (SLU-PP-332)8-week SLU-PP-332 treatment; 3-week STING inhibitor C-176 treatment
8 weeks of SLU-PP-332 in 21-month-old mice reversed age-related albuminuria, kidney mitochondrial dysfunction and inflammation.
Study details
- Studied
- 21-month-old mice (and aging human and mouse kidney tissue)
- Compared with
- Caloric restriction comparison
- Main outcome
- Albuminuria, podocyte loss, mitochondrial dysfunction, inflammatory cytokines
- Authors' conclusion
- An 8-week pan-ERR agonist treatment reversed age-related albuminuria, podocyte loss, mitochondrial dysfunction and inflammation in aged mice, similar to caloric restriction, identifying ERRs as calorie-restriction mimetic targets.
- Limitations
- Mouse study.
-
Targeting ERRs to counteract age-related muscle atrophy associated with physical inactivity: a pilot study.Humans + animalsMyotube differentiation for 15 daysPilot study: muscle biopsies plus in vitro SLU-PP-332 treatment of primary myoblasts
In muscle cells taken from inactive women, SLU-PP-332 lowered oxidative stress and senescence markers and promoted myotube formation; no participants received the drug.
Study details
- Studied
- Women with coxarthrosis (active vs inactive) and myoblasts isolated from inactive women
- Compared with
- Active vs inactive women; untreated myoblasts
- Main outcome
- Expression of NOX4, SIRT1, PGC-1alpha, ERR alpha, FNDC5; myoblast differentiation and oxidative stress
- Sample
- Twenty women (10 active, 10 inactive) undergoing hip arthroplasty
- Authors' conclusion
- SLU-PP-332 down-regulated NOX4, up-regulated SIRT1, PGC-1alpha, ERR alpha and FNDC5 and promoted myotube formation in myoblasts from inactive women; targeting ERRs could be a strategy against muscle atrophy, but mechanisms need clarification.
- Limitations
- Pilot study; SLU-PP-332 tested only in cultured cells from inactive women.
Reported side effects
No human safety data in the published literature; it is studied as a doping target by anti-doping laboratories.

SLU-PP-332: questions people ask
What is SLU-PP-332?
ERR agonist, "exercise mimetic" (small molecule). Activates the estrogen-related receptors that switch on endurance-exercise genes in muscle. Increased endurance and fat burning in mice.
How much does SLU-PP-332 cost?
The cheapest SLU-PP-332 from an independently tested vendor is $0.009 per mg (Andy Peps Studio, Slupp 332 Raw Powder Bulk 99% 100g, $850.00). Across 61 listings from 35 vendors the median is $4.87 per mg.
Where can I buy SLU-PP-332?
35 vendors tested by Finnrick sell SLU-PP-332. The cheapest per mg right now: Andy Peps Studio ($0.009), Baohua Dongnuo Biotechnology BHD ($0.009), LN Peptides ($0.009). 3 of them publish a lab report (COA) for SLU-PP-332; compare lab scores and reports in the table above before buying.
How much bacteriostatic water for 5 mg of SLU-PP-332?
Adding 2 mL of bacteriostatic water to a 5 mg vial of SLU-PP-332 gives 2.5 mg/mL: each 10 units on a U-100 insulin syringe holds 250 mcg. With 1 mL it's 5 mg/mL (500 mcg per 10 units); with 3 mL, 1.667 mg/mL (166.7 mcg per 10 units). More water makes small amounts easier to measure. Mixing charts: 5 mg, 10 mg.
Is SLU-PP-332 FDA approved?
Not approved. Research use only.
Can SLU-PP-332 be compounded in the US?
Not an FDA-approved drug and not nominated for FDA's 503A bulks list, so US pharmacies can't legally compound it. Compounding status for every peptide.
Does SLU-PP-332 work? What does the research say?
Evidence grade C (mostly animal studies), from 6 papers: Several mouse studies show more endurance and less fat gain; no human studies of any kind. SLU-PP-332 is an experimental ERR agonist studied only in mice and cell cultures, where it increased endurance and energy expenditure and reduced fat gain. No human trials exist; a 2026 systematic review states clinical trials are needed. See the papers.
What dose of SLU-PP-332 was used in studies?
SLU-PP-332 is tested only in animals or cells. Studied only in mice (obese, aged and heart-failure models; e.g. 8 weeks of treatment in 21-month-old mice, PMID 37717940) and in cultured cells including human myoblasts (PMID 40692696); the PubMed abstracts found do not state the mg/kg doses used. These are amounts used in published studies or official labels, not a recommendation.
