SLU-PP-332 has become one of the most-discussed compounds in longevity and metabolic research in 2026, nicknamed 'exercise in a bottle'. This is a research overview of what it is and how it works. Note up front: strictly speaking SLU-PP-332 is a small molecule, not a peptide — it's simply grouped with research peptides by most suppliers. Supplied for laboratory research only.
What is SLU-PP-332?
SLU-PP-332 is a synthetic agonist of ERRα (estrogen-related receptor alpha), a regulator of mitochondrial and metabolic gene expression. It is a small molecule rather than a peptide, but it's commonly sold and discussed alongside research peptides because of its metabolic focus.
How the ‘exercise mimetic’ mechanism works
By activating ERRα, SLU-PP-332 is reported in research to switch on many of the same mitochondrial and fat-oxidation genes that endurance exercise turns on — increasing mitochondrial activity and the use of fat for fuel in animal models, without the physical training. Hence the 'exercise mimetic' nickname.
What the research reports
In published animal studies, SLU-PP-332 increased running endurance, raised energy expenditure and reduced fat mass without reducing food intake — a different route to metabolic change than appetite-based drugs.
How it differs from GLP-1 peptides
GLP-1 drugs like retatrutide and semaglutide work mainly by suppressing appetite. SLU-PP-332 works on the opposite side of the equation — metabolic rate and fat burning — which is exactly why longevity and performance researchers find it interesting as a complement rather than a substitute.
Handling in a research setting
SLU-PP-332 is supplied as a lyophilised powder, reconstituted for in-vitro work and stored cool. Independent HPLC purity data is published for every batch on our Purity Reports page.
Frequently asked questions
Is SLU-PP-332 a peptide?
No — it's a small-molecule ERRα agonist, not a peptide, though it's commonly grouped and sold with research peptides because of its metabolic research focus.
What is SLU-PP-332 researched for?
Research models study it for mitochondrial activity, endurance and fat oxidation — it's nicknamed an 'exercise mimetic' because it activates many of the same pathways as endurance exercise.
How does it differ from GLP-1s like retatrutide?
GLP-1s work mainly through appetite suppression; SLU-PP-332 works through metabolic rate and fat burning, a different mechanism.
How is it supplied and verified?
As a lyophilised powder, HPLC-verified with a third-party Certificate of Analysis published per batch. For laboratory research use only.
