SLU-PP-332 Oral
SLU-PP-332 is a synthetic small-molecule pan-agonist of the estrogen-related receptors (ERRα, ERRβ, and ERRγ). ERRα is a transcription factor that regulates genes controlling mitochondrial biogenesis, oxidative phosphorylation, and fatty acid oxidation. By activating these receptors, SLU-PP-332 has been shown in preclinical research to mimic some of the metabolic adaptations associated with aerobic exercise, including increased energy expenditure and enhanced fatty acid metabolism.
In animal studies, SLU-PP-332 administration produced significant increases in running endurance, reduced fat mass accumulation, and improved insulin sensitivity in mouse models of obesity and metabolic syndrome. The compound has also been investigated for its cardioprotective effects, with research showing that ERR agonism improved cardiac function and increased survival in a pressure overload-induced heart failure model. SLU-PP-332 is not approved for human use and remains a research compound only.
In non-medical bodybuilding and biohacking contexts, SLU-PP-332 is discussed as a potential "exercise mimetic" for its effects on mitochondrial function and fat oxidation. Published dosing discussions reference a wide range, with some podcast commentary noting that the reported dosing range spans a thousandfold and that only one end of that range does anything. Forum discussions reference oral doses ranging from 250 mcg to 1,500 mcg daily, with some users reporting effects at higher doses. The 500 mcg strength of Dragon Pharma's SLU-PP-332 aligns with commonly referenced retail dose points.

Pan-ERR Agonist (Research Compound)
SLU-PP-332 belongs to the class of estrogen-related receptor (ERR) agonists. ERRs are a subfamily of nuclear receptors that share structural homology with estrogen receptors but do not bind estrogen. ERRα, the most studied isoform, is highly expressed in tissues with high energy demands, including skeletal muscle, heart, and brown adipose tissue. SLU-PP-332 activates all three ERR isoforms with EC50 values of 98 nM for ERRα, 230 nM for ERRβ, and 430 nM for ERRγ.
The downstream effects of ERR activation include upregulation of PGC-1α, a master regulator of mitochondrial biogenesis, and increased expression of genes involved in fatty acid oxidation and oxidative phosphorylation. In mouse studies, SLU-PP-332 administration at 50 mg/kg twice daily increased running endurance by 70% and running distance by 45% compared to untreated controls. Treated mice also showed reduced fat mass accumulation, with diet-induced obese mice gaining 10 times less fat than untreated controls over 28 days.
The pharmacokinetic properties of SLU-PP-332 include a molecular weight of 290.3 g/mol and a chemical formula of C18H14N2O2. The compound is not water-soluble, which may affect oral bioavailability depending on formulation. In vitro metabolism studies have identified multiple metabolites formed through oxidation and glucuronidation pathways.

Stacking & Cycle Considerations
SLU-PP-332 is not an anabolic compound and is not stacked for muscle-building purposes. In non-medical contexts, it is occasionally referenced alongside other mitochondrial or metabolic support compounds. Dragon Pharma offers MOTS-C and SS-31 as research compounds that target different aspects of mitochondrial function. For thermogenic fat loss approaches, Clenbuterol is commonly referenced.
Because SLU-PP-332 has no established human safety profile, cycle structure and support compounds remain entirely speculative. Any use should be considered experimental.
Managing Side Effects
No human safety data exists for SLU-PP-332. Adverse effects observed in animal studies were not reported as significant at the doses used, but this does not establish safety in humans. The compound's effects on estrogen-related receptor signaling raise theoretical concerns about hormonal and reproductive effects that have not been characterized. Individuals should be aware that any human use is entirely experimental.
Post-Cycle Therapy
SLU-PP-332 is not part of standard post-cycle therapy, and no PCT protocols have been established for this compound. PCT compounds such as Clomid and Nolvadex address the hypothalamic-pituitary-gonadal axis rather than ERR signaling. SLU-PP-332's research focus has been on metabolic and mitochondrial endpoints, not hormonal recovery.
