Quickstart Highlights
SLU-PP-332 is a synthetic small molecule (not a peptide) that acts as a pan-agonist of the estrogen-related receptors ERRα/β/γ — an “exercise mimetic” developed in the Burris/Elgendy lab at Saint Louis University[1][5]. All evidence is preclinical — in mice only. The schedule below reproduces published murine-equivalent regimens (mg/kg-derived for a ~25 g mouse) and is not a recommended human protocol. It is an unapproved research chemical, not a medicine, with no human trials and no FDA approval — presented for research and educational use only.
- Add 3.0 mL bacteriostatic water to one 5 mg vial → ~1.67 mg/mL (1,667 mcg/mL), the largest practical dilution for accurate dosing.
- 1,250–2,500 mcg/day (murine-equivalent, for a ~25 g mouse), split into two divided doses — not a human dose.
- At ~1.67 mg/mL, 1 unit ≈ 16.67 mcg; 625 mcg ≈ 37.5 units and 1,250 mcg ≈ 75 units on a U-100 syringe.
- Lyophilized: store at −20 °C (−4 °F); once reconstituted, refrigerate at 2–8 °C (35.6–46.4 °F) and do not freeze the solution.
- Important: Start with the Prep & Injection Guide — it covers the preparation and safety basics every protocol on this site assumes.
Dosing & Reconstitution Guide
A single practical dilution with accurate once-daily dosing, step by step
| Phase / Week(s) | Dose & Frequency | Volume (U-100 units / mL) |
|---|---|---|
| Weeks 1–2 | 625 mcg (2× daily · 1,250 mcg/day) | 37.5 units (0.375 mL) per dose |
| Weeks 3–8 | 1,250 mcg (2× daily · 2,500 mcg/day) | 75 units (0.75 mL) per dose |
- Reconstitute: Add 3.0 mL bacteriostatic water to one 5 mg vial → final concentration ~1.67 mg/mL (1,667 mcg/mL).
- Murine daily dose: 1,250–2,500 mcg/day (murine-equivalent for a ~25 g mouse), given as two divided doses. This is not a human dose.
- Easy measuring: At ~1.67 mg/mL, 1 unit ≈ 16.67 mcg on a U-100 syringe (units = mcg ÷ 16.67). The large 3.0 mL dilution keeps every dose at 37.5 units or more for accurate measuring.
- Storage: Lyophilized: store at −20 °C (−4 °F); after reconstitution, refrigerate at 2–8 °C (35.6–46.4 °F) and do not freeze the mixed solution.
- Route & frequency: published murine studies used intraperitoneal administration twice daily (25–50 mg/kg)[1][2]. The daily mcg values above are murine-equivalent (expressed for a ~25 g mouse), not approved human doses. No reputable source supports a human protocol for this compound.
Reconstitution Steps
Draw 3.0 mL of bacteriostatic water into a sterile syringe.
- Release it slowly down the vial’s inner wall to limit foaming.
- Swirl or roll gently until fully dissolved — don’t shake.
- Label with the date and concentration, then refrigerate at 2–8 °C (35.6–46.4 °F), shielded from light.
- The 3.0 mL dilution is deliberately large so each dose reads at 37.5 units or more, where U-100 syringe markings are most precise. Avoid freezing the reconstituted solution and protect it from light. SLU-PP-332 is a small molecule, not a peptide.

Protocol Overview
A concise summary of the murine-based regimen reproduced from published preclinical studies.
- ▪Mechanism: Pan-agonist of estrogen-related receptors (ERRα/β/γ) that activates an aerobic-exercise gene program and boosts mitochondrial function — reported in mice only, not established in humans[1][2].
- ▪Published route: Intraperitoneal administration in mice, twice daily (25–50 mg/kg); cycle length was 8 weeks in published studies.
- ▪Murine dose range: 1,250–2,500 mcg/day (for a ~25 g mouse) in two divided doses — murine-equivalent, not a human dose.
- ▪Reconstitution: 3.0 mL bacteriostatic water per 5 mg vial gives ~1.67 mg/mL for accurate unit measurements.
- ▪Storage: Keep the dry vial frozen at −20 °C (−4 °F); once mixed, refrigerate at 2–8 °C and do not freeze the solution.
Dosing Protocol
The murine-equivalent dosing framework reproduced from published preclinical studies (not a human protocol).
- ▪Initial phase (Weeks 1–2): 1,250 mcg/day — 625 mcg per injection, twice daily.
- ▪Maintenance phase (Weeks 3–8): 2,500 mcg/day — 1,250 mcg per injection, twice daily.
- ▪Route: Intraperitoneal in published murine models; the doses above are murine-equivalent (for a ~25 g mouse), not human doses.
- ▪Cycle length: 8 weeks in published studies; some research extends to 12–16 weeks.
- ▪Frequency & timing: Twice per day at consistent intervals, reflecting published murine regimens.
Storage Instructions
Correct storage is what preserves the compound’s stability and activity.
- ▪Lyophilized: Hold the dry vial at −20 °C (−4 °F) in dry, dark conditions and limit moisture exposure[7].
- ▪Reconstituted: Refrigerate at 2–8 °C (35.6–46.4 °F), protected from light; avoid freeze–thaw cycles of the mixed solution[8].
- ▪Handling: Let frozen vials warm to room temperature before opening so condensation won’t form, and keep the solution clear of heat and direct light.
- ▪Freeze–thaw: Avoid repeated freeze–thaw cycles of the reconstituted solution.
Important Notes
Practical points that keep daily administration safe and consistent.
- ▪Sterile technique: Use a fresh sterile U-100 insulin syringe each time and drop it straight into a puncture-proof sharps container afterward.
- ▪Site rotation: Move between abdomen, thighs and upper arms to reduce local irritation and lipohypertrophy[9].
- ▪Slow injection: Push the plunger slowly and pause a few seconds before withdrawing the needle to prevent backflow.
- ▪Recordkeeping: Log the daily dose, injection site and any observations to keep the protocol consistent.
- ▪Regulatory note: SLU-PP-332 is a WADA-prohibited substance (S4.5 metabolic modulators) and is not FDA-approved; there are no human trials and no established human dose[10].
How This Works
SLU-PP-332 is a synthetic small molecule (not a peptide) that acts as a pan-agonist of the estrogen-related receptors ERRα, ERRβ and ERRγ, with strongest activity at ERRα[1][2]. It was developed in the Burris/Elgendy lab at Saint Louis University.
- As an “exercise mimetic,” it engages metabolic pathways normally activated by physical training. In mouse studies, acute administration switched on an aerobic-exercise transcriptional program, increased mitochondrial respiration and fatty-acid oxidation in skeletal muscle, and improved endurance and cardiometabolic measures — without the mechanical stress of actual exercise[3][6].
- Additional mouse work has reported reversal of mitochondrial dysfunction and inflammation in aging kidney models, alleviation of metabolic syndrome, and improved cardiac fatty-acid metabolism in heart-failure models[4]. Mouse studies used intraperitoneal injection; some users take it orally, but no oral protocol is established.
- Critical caveat: all evidence is preclinical, in mice only. There are no human trials, no FDA approval, and no established human dose for SLU-PP-332. The murine benefits should be read as hypotheses; there is no basis to assume they translate to humans.
- SLU-PP-332 is not an approved medicine. It is an unapproved research chemical presented here for research and educational purposes only — not for human consumption.
Lifestyle Factors
Contextual factors relevant to preclinical research with this compound.
- ▪Exercise context: SLU-PP-332 was studied alongside exercise training in some murine models, suggesting possible synergistic metabolic effects.
- ▪Diet: Diet composition (standard chow vs. high-fat diet) influenced metabolic outcomes in published mouse studies.
- ▪Environment: Standardize temperature and housing conditions, which can affect metabolic readouts in research protocols.
- ▪Handling: Compound stability and consistent handling procedures are critical for reproducible results.
Potential Benefits & Side Effects
What murine studies describe. There is no human evidence; do not assume these effects translate to humans.
- ▪Metabolic (mice): Enhanced mitochondrial function, increased fatty-acid oxidation and improved glucose tolerance in diet-induced obese mice[2].
- ▪Cardiac & renal (mice): Ameliorated heart failure via cardiac fatty-acid metabolism, and reversed mitochondrial dysfunction in aging kidney models[3][4].
- ▪Endurance (mice): Increased treadmill running capacity and muscle oxidative capacity in mice[1].
- ▪Human safety unknown: No human data on tolerability, pharmacokinetics or adverse effects exist; no clinical trials have been conducted[13].
- ▪Injection-site reactions: Mild redness, tenderness or soreness can occur; rotating sites helps.
- ▪Unknown long-term profile: Human safety data is limited, so caution and monitoring are advised.
- ▪Sport restriction: SLU-PP-332 is a WADA-prohibited substance (S4.5 metabolic modulators) for athletes.
Injection Technique
General subcutaneous technique, following established clinical best-practice guidance[14][15]. Note: published murine studies used intraperitoneal administration; the subcutaneous route is not validated for this compound.
- ▪Wash your hands well with soap and water.
- ▪Wipe the vial stopper with an alcohol swab and let it air-dry.
- ▪Choose a site (abdomen, thigh, or upper arm) and clean it with a fresh alcohol swab, letting it dry fully[15].
- ▪Draw the intended dose, then check for air bubbles and push any out.
- ▪Pinch a skinfold at the chosen site between thumb and forefinger.
- ▪Insert the needle into the pinch at a 45–90-degree angle (use 45 degrees if the fat layer is thin)[14].
- ▪Skip aspiration for subcutaneous shots — it isn’t needed[14].
- ▪Press the plunger slowly and steadily until it’s fully down.
- ▪Wait 5–10 seconds, then pull the needle straight out to prevent leakage.
- ▪Drop the used syringe straight into a puncture-proof sharps container — never recap a needle.
- ▪Return the reconstituted vial to the fridge right away.
- ▪Rotate the injection site each day to prevent irritation and lipohypertrophy[9].
- ▪Watch the site for excess redness, swelling, or signs of infection.
