Primary entity: SLU-PP-915Also known as: slupp-915 (search spelling); compound 10sClass: Pan-ERR agonist — not a peptideCluster: GLP-1 & metabolic

SLU-PP-915 is a research designation for a synthetic pan-agonist of the estrogen-related receptors (ERRα, ERRβ, and ERRγ), identified in a St. Louis University Pharmaceutical Program (SLU-PP) chemistry series (compound 10s). It is chemically a small molecule (literature describes a boronic-acid-containing thiophene template), not a peptide, and not an FDA-approved drug. Related tool compound SLU-PP-332 is better known in popular “exercise mimetic” coverage; SLU-PP-915 is a sibling pan-ERR agonist characterized for gene-expression and pharmacology work, with later analytical papers mapping metabolism for potential doping-control relevance.

Important chemistry callout:

“Slupp-915” is a compacted search spelling of SLU-PP-915, not a different molecule. Neither name is a peptide. ERR agonists are nuclear-receptor ligands — a different class from incretin peptides, SARMs, and PPARδ agonists like cardarine.

Regulatory / sport status at a glance (as of early Oct 2026):

Not FDA-approved. No authorized medicine. Evidence base is primarily chemical / in vitro / animal pharmacology plus anti-doping analytical characterization. Explicit year-by-year WADA Prohibited List naming for SLU-PP-915 can lag popular claims — some secondary sources assert forthcoming or list-year naming alongside SLU-PP-332; athletes should treat non-approved exercise-mimetic metabolic agents as high risk and check current WADA list + GlobalDRO, not forums. S0 (non-approved substances) and/or metabolic-modulator class logic may apply even when a code is not spelled out. Gray-market “research” vials/capsules are not clinical trial supply.

Key takeaways

  • Not a peptide — pan-ERR agonist small molecule (SLU-PP-915; search spelling slupp-915).
  • Naming comes from the St. Louis University Pharmaceutical Program series; paper identity includes compound 10s.
  • Sibling curiosity: SLU-PP-332 (often the headline “exercise mimetic” ERR tool) — related, not identical.
  • Not FDA-approved; human therapeutic approval pathway not established in the sources cited on this page.
  • Anti-doping labs have published metabolism / detection work flagging doping potential — athletes: verify current rules.
  • No dosage chart on this site.

Who is this profile for — and who is it not for?

For: readers who saw “slupp-915” / SLU-PP-915 in forums or AI answers and need naming confirmation, chemistry-class literacy, and evidence-maturity hedges.

Not for: anyone seeking a buy link, an endurance protocol, a stack with SLU-PP-332, or medical advice.

What is SLU-PP-915?

SLU-PP-915 is a potent pan-ERR agonist from a structure-based medicinal-chemistry series designed around ERR pharmacology (building from earlier ERR ligand templates such as acyl-hydrazide / GSK-4716-class starting points in the paper narrative). Optimization introduced a boronic acid moiety associated with retained agonist activity and improved microsomal stability in the authors’ assays. Gene-expression work reported upregulation of ERR target genes (e.g., PGC-1α-pathway-related and metabolic genes such as LDHA / PDK4 / DDIT4 in the paper’s framing) in vitro and in vivo.

Also known as

  • SLU-PP-915 — canonical research designation (St. Louis University Pharmaceutical Program).
  • slupp-915 / slu pp 915 / slu-pp915 — compacted or punctuated search spellings of the same name; not a second drug.
  • Compound 10s — internal series number in the ACS/medicinal-chemistry identification paper.
  • SLU-PP-332 — related but distinct pan-ERR agonist often featured in endurance/exercise-mimetic coverage; do not collapse the two.
Myth callout — “slupp-915 is a different peptide”:

AI and forums sometimes invent a second entity from the compacted spelling or file it under peptides. Slupp-915 = SLU-PP-915, and it is a small-molecule ERR agonist.

How is SLU-PP-915 classified?

Preclinical / chemical-biology research tool — synthetic pan-ERR agonist. On this site it sits in the glp1-metabolic cluster for educational comparison with other “exercise mimetic” and metabolic curiosities — with an explicit not-a-peptide banner.

It is not a dietary supplement, not an approved drug, and not the same entity as SLU-PP-332.

What is SLU-PP-915 not?

SLU-PP-915 is not…Why that matters
A peptideDifferent chemistry (nuclear-receptor small molecule)
An estrogen / ER hormone drugERRs are related orphan receptors — not the same as classical ER agonists
Identical to SLU-PP-332Sibling series member; different compound
FDA-approvedNo label
A proven safe “cardarine replacement”Different target; thin human evidence; sport risk hedges
Something we dose or sourceRefusal

How is SLU-PP-915 thought to work?

Estrogen-related receptors (ERRs) are orphan nuclear receptors that regulate transcriptional programs for mitochondrial function, oxidative metabolism, and energy homeostasis. Pan-agonists aim to activate ERRα, ERRβ, and ERRγ. Research interest frames this as a potential exercise-mimetic / metabolic pathway — conceptually adjacent to, but distinct from, PPARδ agonism (cardarine) and AMPK activation (ATX-304 / AICAR-class tools).

What human vs animal vs label evidence exists?

Evidence typeWhat exists (summary)Maturity
Chemistry / in vitroIdentification, binding/co-transfection, gene expressionCell

Avoid inventing human endurance % improvements or therapeutic doses.

What has SLU-PP-915 been studied for?

Primarily tool-compound pharmacology: ERR target-gene regulation and series SAR (structure–activity) with metabolic/exercise-phenotype rationale shared with related ERR agonists. Anti-doping research studies detection and metabolites because of performance-enhancement concern. Studied as a research ligand ≠ approved therapy.

What safety topics come up?

Human clinical safety packages comparable to approved drugs are not what this entity has in the public evidence ladder summarized here. Nuclear-receptor agonists can have broad transcriptional effects; unknown long-term risk is a core literacy point. Unregulated vendor products: unknown identity/purity. Not medical advice.

What is SLU-PP-915's regulatory status?

  • U.S.: Not FDA-approved.
  • Sport: Anti-doping literature explicitly discusses SLU-PP-332 and SLU-PP-915 as compounds with doping potential and publishes detection methods. Whether a given WADA list names SLU-PP-915 in a specific calendar year can change — do not rely on forum screenshots. Check current WADA Prohibited List and GlobalDRO. Non-approved substance (S0) and metabolic-modulator class interpretations are commonly discussed in secondary literacy.
  • Gray market: Research-chemical marketing is not a clinical pathway.

Why doesn't this page include a dosage chart?

No approved labeled dose; evidence is research-tool grade; “slu-pp-915 dosage” / “slupp-915 cycle” queries seek gray-market protocols. Literacy refusal.

Peptide reconstitution pages are not applicable. Cluster primer: What are peptides?

  • SLU-PP-332 — related pan-ERR agonist (often the better-known exercise-mimetic headline compound); do not equate doses or identity.
  • Cardarine (GW501516) — PPARδ agonist (different receptor; discontinued + WADA-classic toxicity story).
  • ATX-304 — AMPK network activator investigational small molecule.
  • Tesofensine — monoamine reuptake investigational agent (not a peptide).
  • Semaglutide / Tirzepatide — approved peptide incretin drugs (different class).

Frequently asked questions

Is SLU-PP-915 a peptide?

No. It is a small-molecule pan-ERR agonist.

Is “slupp-915” a different compound?

No. It is a compacted search spelling of SLU-PP-915. Treat them as the same research designation unless a primary source shows otherwise.

What does SLU-PP mean?

In this series it denotes the St. Louis University Pharmaceutical Program compound numbering — not a peptide abbreviation.

Is SLU-PP-915 the same as SLU-PP-332?

No. They are related pan-ERR agonists from the same research ecosystem/series family, but they are distinct chemical tools. Popular coverage often features SLU-PP-332; that does not make 915 identical.

Is SLU-PP-915 FDA approved?

No, not as of November 10, 2026.

Is it banned in sports?

Anti-doping scientists have characterized it for detection because of doping potential. Exact list naming can vary by year — athletes must check the current WADA list and GlobalDRO rather than screenshots.

Why is this on a peptide tutorials site?

Exercise-mimetic and metabolic search demand clusters ERR tools with peptides. We publish a literacy profile with naming + chemistry-class correction.

Why no dosage information?

YMYL policy and lack of approved labeling. We will not invent a research-chem cycle chart.
