SLU-PP-332 is a potent pan-ERR agonist — a synthetic small-molecule compound that activates estrogen-related receptors alpha, beta, and gamma simultaneously. Developed by researchers at Washington University in St. Louis, it has gained significant attention in the scientific community for its role in modeling the metabolic effects of endurance exercise at the cellular and systemic level. When researchers buy SLU-PP-332 tablets, they gain access to a uniquely bioavailable oral format that simplifies research protocols significantly compared to injection-based preparations. For a broader overview of research peptides and small molecules, see our Complete Guide to Peptides.
Detailed Mechanism of Action
SLU-PP-332 functions as a pan-agonist of all three estrogen-related receptors: ERRα (ESRRA), ERRβ (ESRRB), and ERRγ (ESRRG). These nuclear receptors are constitutively active orphan receptors — they do not require an endogenous ligand to signal, but their activity can be powerfully amplified by synthetic agonists such as SLU-PP-332. When researchers buy SLU-PP-332 tablets and apply them in research models, the compound binds to and stabilizes the ERR ligand-binding domain, driving conformational changes that enhance coactivator recruitment — particularly PGC-1α and PGC-1β, the master regulators of mitochondrial biogenesis.
The downstream transcriptional program activated by SLU-PP-332 closely mirrors what is observed following sustained aerobic exercise. Key gene sets upregulated include those encoding enzymes of fatty acid β-oxidation (CPT1A, ACSL1, HADHA), components of the electron transport chain (NDUFB5, SDHA, COX5A), and proteins involved in mitochondrial dynamics and fission/fusion (MFN2, DRP1). The compound also engages VEGF and angiogenic gene networks, suggesting potential utility in models of vascular adaptation and cardiac remodeling. Researchers who buy SLU-PP-332 tablets gain a reproducible, orally bioavailable tool that achieves consistent plasma levels without the variability inherent to injectable formulations.
Importantly, the oral tablet format offered by PSPeptides is formulated for maximum absorption and bioavailability. The tablet matrix is engineered to protect the active compound through gastric transit and facilitate efficient absorption in the small intestine, ensuring that the active concentration of SLU-PP-332 reaching systemic circulation remains high and reproducible across research administrations. This makes it significantly easier to design standardized, repeatable in vivo protocols compared to working with raw lyophilized powder.

Published Research on SLU-PP-332
The foundational research on SLU-PP-332 was published by Bhatt et al. and colleagues at Washington University School of Medicine, demonstrating that systemic administration of SLU-PP-332 in mouse models produced dramatic increases in running endurance — up to 70% improvement in time-to-exhaustion compared to controls — without any exercise training. These landmark findings established SLU-PP-332 as the first compound to reliably produce an endurance exercise phenotype through direct pharmacological ERR activation alone. Researchers who buy SLU-PP-332 tablets can now investigate these same ERR-mediated pathways with the convenience of oral dosing.
Subsequent research has expanded the investigated applications of SLU-PP-332 to include cardiac hypertrophy models, obesity and metabolic syndrome research, and neurodegenerative disease studies where mitochondrial dysfunction plays a central role. A 2023 preclinical study demonstrated that SLU-PP-332 attenuated pathological cardiac hypertrophy markers in pressure-overload models, pointing to cardiac research as a highly productive avenue for this compound. External resources on ERR biology and SLU-PP-332 can be found at PubMed (SLU-PP-332 endurance research) and NIH/PubMed (ERR agonist cardiac research). For researchers interested in metabolic and weight-related research compounds, our Best Peptides for Weight Loss Research guide provides valuable context.
The oral bioavailability profile of SLU-PP-332 in tablet form has been shown to produce consistent pharmacokinetic behavior, with peak plasma concentrations achieved within 1–2 hours post-administration in animal models. This predictable absorption profile is one of the key advantages of choosing to buy SLU-PP-332 tablets over other preparation formats. Researchers planning chronic dosing studies particularly benefit from the reduced burden and improved compliance that oral tablets provide versus subcutaneous or intraperitoneal administration routes.
