COA included with every batch

Overview

What it is.

SLU-PP-332 is a small-molecule ERR (estrogen-related receptor) agonist developed in an academic research setting, studied for effects on muscle-metabolism gene expression that resemble changes observed under endurance-exercise conditions. It is an early-stage research chemical, chemically distinct from the peptides in this catalog.

Research Areas

  • Studied in preclinical research models for its role in ERR-pathway activation
  • Studied for potential effects on skeletal-muscle metabolic gene expression
  • Studied as part of early academic research into exercise-mimetic compounds

Research Deep-Dive

How it works.

SLU-PP-332 is not a peptide — it is a synthetic small-molecule chemical, first characterized in a laboratory at Saint Louis University, that activates a family of nuclear receptors called estrogen-related receptors (ERRα, ERRβ, ERRγ). It is grouped alongside peptides in online marketing because it shares the "exercise mimetic" framing, but its chemistry and research base are entirely different.

ERR receptors sit downstream of the cellular pathways activated by aerobic exercise and regulate mitochondrial biogenesis and fat-burning gene programs. SLU-PP-332 activates all three ERR subtypes directly, which in animal studies produced some of the muscle and metabolic adaptations associated with endurance training, without the mice actually exercising.

Use Cases Explored

  • Preclinical research into ERR-receptor pan-agonism
  • Animal-model research into skeletal-muscle metabolic gene expression
  • Early academic research into exercise-mimetic compound classes

The Evidence

Preclinical endurance studies (mouse models)

Animal studies have reported 20-30% improvements in running endurance without training, along with a shift toward oxidative (Type I) muscle fiber type and increased fatty-acid oxidation — all findings from mouse research, with no human data.

Preclinical metabolic-syndrome studies

In diet-induced obesity mouse models, SLU-PP-332 increased energy expenditure and fat oxidation and improved glucose tolerance and insulin sensitivity — again, animal-only findings.

No human trials

SLU-PP-332 has never been studied in humans and has no FDA Investigational New Drug application on record. It has also been placed under WADA's prohibited metabolic-modulator category despite the total absence of human data — an unusual regulatory posture for a compound this early-stage.

Questions

SLU-PP-332 FAQ

What is SLU-PP-332 studied for?+

SLU-PP-332 is studied as a small-molecule ERR-agonist, examined in preclinical models for effects on skeletal-muscle metabolic gene expression that resemble changes seen under endurance-exercise conditions.

Is SLU-PP-332 a peptide like the others in this catalog?+

No — it's a small-molecule research chemical, chemically distinct from peptides, developed in an academic research setting. It's an early-stage compound with a much smaller research base than established peptides in this catalog.

How should SLU-PP-332 be handled and stored?+

It ships as a lyophilized powder. Reconstitute with bacteriostatic water and refrigerate at 2–8°C after mixing — good for roughly 4–6 weeks refrigerated, or up to 24 months unreconstituted in a cool, dry place.

What testing does this batch undergo?+

Every batch is HPLC tested for purity and identity, plus sterility and endotoxin screening, before release. The Certificate of Analysis for that lot ships with your order.
