Start here

What is SLU-PP-332?

SLU-PP-332 is an experimental exercise mimetic, a compound designed to switch on some of the same metabolic programs your body runs during endurance training. In studies it boosted fat burning, improved mitochondrial (the power plants inside your cells) function (the cell structures that produce energy), and increased endurance-type muscle fibers. It is strictly a research compound: the evidence so far comes from animal studies, and it is not FDA approved.

How it works in your body

Think of your cells like little factories that need power plants (mitochondria (the power plants inside your cells)) to function. When you exercise regularly, your body builds more and better power plants, making you more energetic and efficient at burning fuel. SLU-PP-332 flips the same switches that exercise does—specifically targeting receptors called ERRs (estrogen-related receptors) that control your mitochondria and metabolism. It's like telling your body 'hey, we're training hard' even when you're sitting still. The result? Your metabolism revs up, you burn more fat, and your endurance improves—mimicking weeks of cardio training.

The deeper mechanism, for the curious

SLU-PP-332 is a lab-made drug that switches on the whole family of estrogen-related receptors (ERRs; a pan-agonist (a compound that switches a receptor on)). Its strongest effect is at ERRα (EC50 = 98 nM), with activity at ERRβ and ERRγ (EC50s = 230 and 430 nM respectively). EC50 is the amount needed for half of the maximum effect, so a lower number means stronger. ERRs are orphan nuclear receptors (receptors inside the cell nucleus whose natural trigger is not known). They control the genes for mitochondrial (the power plants inside your cells) biogenesis (building new mitochondria, the cell's energy makers; the PGC-1α pathway), oxidative phosphorylation (how cells make energy using oxygen), fatty acid β-oxidation (burning fat for fuel), and the tricarboxylic acid (Krebs) cycle (a series of steps cells use to extract energy from food). Once ERRs are switched on, SLU-PP-332 makes cells produce more of DNA damage-inducible transcript 4 (Ddit4) and increases type IIa oxidative skeletal muscle fiber content (muscle fibers that use oxygen to make steady energy). The compound enhances mitochondrial respiration (energy production) in skeletal myoblasts (young muscle cells) and increases whole-body energy use without affecting appetite or food intake. ERRα activation specifically drives the genetic program that switches on during an aerobic exercise session, and studies confirm that ERRα is critical for the exercise-enhancing effects. The compound shows metabolic benefits including better glucose homeostasis (steady blood sugar), higher insulin sensitivity (how well your body responds to insulin), and less body fat (adiposity) in models of diet-induced and genetic obesity.

Evidence check

Animal studies only — extensive

It has been studied a lot, but in animals, not people. Results in mice or rats often don't carry over to humans.

Every numbered marker on this page links to one of the 6 sources at the bottom.

Metabolic Enhancement

Powerfully activates ERR receptors to boost mitochondrial function, energy expenditure, and fat oxidation—mimicking the metabolic effects of endurance exercise

94/100

Exercise Mimic (acts like exercise)

Induces aerobic exercise genetic programs without physical exertion, increasing oxidative muscle fibers and endurance capacity

91/100

Fat Loss Support

Reduces fat mass through enhanced metabolism rather than appetite suppression, supporting body composition improvements

What the research points to

  • Switches on the same energy-handling pathways that kick in during endurance exercise—without the sweat
  • Boosts mitochondrial (the power plants inside your cells) function (mitochondria are the parts of cells that make energy), giving your cells more energy-producing powerhouses
  • Increases oxidative muscle fibers (muscle fibers that use oxygen to make steady energy, the kind that excel at endurance activities)
  • Helps your body burn fat more efficiently by speeding up fatty acid oxidation (burning fat for fuel)
  • May improve insulin sensitivity (how well your cells respond to insulin) and blood sugar control
  • Supports metabolic flexibility—your body's ability to switch between fuel sources

The most-asked question

How much SLU-PP-332 do I take?

The research-reported range is 500 mcg, once daily.

  1. Endurance/metabolic research, Experimental use

    500 mcg - 1 mg

    • How often
      Once daily
    • For how long
      8-12 weeks (research use)
    • How
      Injection under the skin

    No human trials exist; early studies in mice showed exercise-like and metabolic effects from switching on ERR targets (cell switches that control energy use) 12. The dose shown is the range used in the research and biohacking community, not a validated human dose.

Adjusting your dose

You're at the right dose if…

  • Improved exercise endurance and recovery
  • Gradual fat loss with maintained muscle
  • Stable energy throughout the day
  • Better overall metabolic markers if tested

Consider going up if…

  • You've used the starting dose for 2+ weeks with no issues
  • You're not noticing expected metabolic improvements
  • Your body weight and composition goals aren't progressing

Go down if…

  • You experience persistent GI discomfort
  • Energy levels become erratic or you feel overstimulated
  • Any unexpected side effects arise
  • Sleep quality deteriorates

The ceiling: 1500 mcg per day (higher doses haven't shown additional benefits in available research)

Reconstitution, in plain words

How do I mix SLU-PP-332?

Peptides usually arrive as a freeze-dried powder in a small vial. “Reconstitution” just means adding sterile water back in so you can measure a dose. Here's how it works for SLU-PP-332:

What you need

  • DMSO (dimethyl sulfoxide) to dissolve the powder — SLU-PP-332 does not dissolve in water
  • Insulin syringes (29-31 gauge) for injection
  • Alcohol swabs for cleaning
  • Oral tablets/capsules don't require reconstitution

A worked example

SLU-PP-332 does not dissolve in bacteriostatic water: its measured solubility in pH 7.4 phosphate-buffered saline is 0.2 μM (about 0.06 mcg/mL) 5. In published mouse studies the powder was first dissolved in DMSO as a stock, then diluted to 5 mg/mL in 12% DMSO and 15% Cremophor in PBS for intraperitoneal injection 6.

Working out your dose

For a 500mcg dose at 5mg/mL: draw 0.1mL (10 units on a standard insulin syringe). For 1000mcg: draw 0.2mL (20 units).

Or let the calculator do it

Three quick questions — your vial, your water, your dose — and it tells you the exact syringe mark. “Find dose amount” is preloaded with SLU-PP-332's recorded schedule.

Injection sites & technique

Where do I inject SLU-PP-332?

The best spots

  • Belly fat area (2 inches from navel)
  • Front or outer thigh
  • Back of upper arm

How to do it, step by step

  • Wash hands thoroughly with soap and water
  • Clean injection site with alcohol swab, let air dry
  • Pinch about an inch of skin
  • Insert needle at 45-90 degree angle
  • Push plunger slowly and steadily
  • Wait 5 seconds, then remove needle and apply light pressure

Injection under the skin or by mouth (published mouse studies used injection into the belly cavity)

Timing

When do I take SLU-PP-332?

Best time of day

Morning dosing aligns with your body's natural metabolic rhythm. If taking before exercise, dose 30-60 minutes prior for optimal effect. Can also split doses between morning and early afternoon.

With or without food?

Can be taken with or without food. Some users prefer taking with a light meal to minimize any potential gastrointestinal discomfort.

Taking it with other peptides

If combining with other metabolic compounds, space them out and start each one separately to identify individual effects. Some users stack with L-Carnitine for enhanced fat oxidation support.

The honest list

What side effects could SLU-PP-332 cause?

Common — usually mild

These show up most often. They usually fade as your body adjusts.

  • Mild GI discomfort

    Some users report mild stomach upset, especially when starting. This is typical of compounds that affect metabolic pathways and usually resolves quickly.

    What to do Take with a light meal. Start with lower doses and increase gradually. Symptoms typically improve within the first week.

  • Increased energy

    You might feel more energetic than usual as your mitochondria (the power plants inside your cells) become more active. This is actually the compound working as intended.

    What to do Channel the extra energy into physical activity if possible. Avoid dosing late in the day if it affects sleep.

  • Mild warmth or temperature increase

    A slight increase in body temperature can occur as metabolic rate increases. Think of it like your internal furnace burning a bit hotter.

    What to do Stay well-hydrated. This effect is usually mild and indicates the compound is activating metabolic pathways.

Less common

Worth knowing about, but most people never see these.

  • Changes in appetite

    Some users notice shifts in hunger patterns. Interestingly, research shows the compound doesn't primarily work by reducing appetite—weight loss occurs through metabolic enhancement.

    What to do Maintain regular eating patterns. If appetite changes significantly, consult with a healthcare provider.

  • Mild headache

    Occasional headaches may occur during the first few days as your body adjusts to enhanced metabolic activity.

    What to do Stay hydrated, rest if needed. Usually resolves within the first week. Consider reducing dose if persistent.

Serious — stop and get medical help

Rare, but if any of these happen, stop and contact a medical professional.

  • Allergic reaction

    Rare, but possible with any compound. Watch for hives, swelling, or difficulty breathing.

    What to do STOP immediately and seek emergency medical care if you experience signs of severe allergic reaction.

SLU-PP-332 is a research compound, not an FDA-approved medication. Never start, stop, or change your dosing without guidance from a qualified healthcare provider. This information is for educational purposes only—not medical advice.

What it mixes badly (and well) with

Medications

  • Avoid
    Diabetes medications (metformin, insulin)

    May add to blood sugar-lowering effects. Risk of hypoglycemia (dangerously low blood sugar). Requires physician supervision and possible dose adjustment.

  • Avoid
    Thyroid medications (levothyroxine)

    Both speed up metabolism (how the body uses energy). Combining them may over-stimulate it. Consult an endocrinologist (hormone specialist).

  • Check first
    Blood pressure medications

    Metabolic changes may affect the heart and blood pressure. Monitor blood pressure closely.

  • OK together
    Statins

    Generally considered safe to combine. Both may actually complement each other for metabolic health.

Other peptides

  • OK together
    BPC-157

    Can be combined safely. BPC-157 focuses on tissue healing while SLU-PP-332 targets metabolism—different mechanisms that may complement each other.

  • OK together
    TB-500

    Safe to combine. TB-500 supports tissue repair and recovery, which may complement the metabolic enhancement from SLU-PP-332.

  • OK together
    GHK-Cu

    Can be used together. GHK-Cu works on cellular regeneration through different pathways.

  • Avoid
    Semaglutide

    Use caution—both affect metabolism and glucose. Combining may lead to excessive metabolic effects. Consult a physician.

Supplements

  • OK together
    L-Carnitine

    May work well together; both support fat burning (fat oxidation). A popular combination in metabolism-focused protocols.

  • OK together
    CoQ10

    Safe and potentially complementary. Both support mitochondria (the parts of cells that make energy) in different ways.

  • Check first
    Caffeine/Stimulants

    Use caution—combining may lead to excessive stimulation or strain on the heart and blood vessels.

  • Check first
    Berberine

    Both affect how the body handles blood sugar. May work well together, but monitor blood sugar if combining.

Who it tends to suit

Metabolic Syndrome Warriors

If you're battling the frustrating combination of belly fat, blood sugar issues, and sluggish metabolism, SLU-PP-332 targets the exact pathways that go haywire in metabolic syndrome. It's like giving your metabolism a personal trainer that works 24/7.

Exercise-Limited Individuals

Injuries, disabilities, or conditions that prevent normal exercise don't have to mean giving up on metabolic health. SLU-PP-332 activates exercise pathways even when you can't hit the gym, potentially maintaining metabolic function during recovery periods.

Endurance Athletes Seeking an Edge

For those already training hard, SLU-PP-332 may amplify your body's natural adaptation to exercise. Research shows it synergizes with actual training, potentially helping you get more benefit from every workout.

Aging Adults Fighting Metabolic Decline

As we age, the energy-making parts of our cells (mitochondria (the power plants inside your cells)) become less efficient and metabolism slows. SLU-PP-332 acts on ERR targets (cell switches that control energy use), potentially helping maintain youthful metabolic capacity even as birthdays add up.

The safety picture overall

SLU-PP-332 has demonstrated a favorable safety profile in extensive preclinical (animal or lab studies, not human trials) studies. Mouse studies showed no severe adverse events even at relatively high doses, with researchers noting improvements in metabolic markers without negative effects on appetite, behavior, or organ function. The compound appears well-tolerated in animal models, though human clinical trials are still needed to fully establish its safety profile in people.

Most safety data comes from mouse studies conducted by Thomas Burris and colleagues at Saint Louis University and later the University of Florida. While preclinical (animal or lab studies, not human trials) results are encouraging, large-scale human clinical trials have not yet been completed. Always work with a healthcare provider when considering research compounds.

Keeping it good

How do I store SLU-PP-332?

Before mixing (powder)

Store powder or tablets at room temperature (59-77°F / 15-25°C) in a cool, dry place away from direct sunlight. Refrigeration extends shelf life. Keep in original sealed container with desiccant if provided.

After mixing (liquid)

If using injectable form, refrigerate at 36-46°F (2-8°C). Never freeze. Keep away from light. Oral forms should remain at room temperature in original packaging.

Signs it has gone bad

  • Discoloration or yellowing of powder/solution
  • Cloudy appearance (solution should be clear)
  • Unusual odor
  • Clumping or crystallization of powder

Not our opinion — the published record

What the studies actually found about SLU-PP-332

2023

Synthetic ERRα/β/γ Agonist Induces an ERRα-Dependent Acute Aerobic Exercise Response and Enhances Exercise Capacity

This foundational study showed that SLU-PP-332 increases mitochondrial function (the energy-making parts of cells) and cellular respiration (energy production) in muscle cells. When given to mice, it boosted oxidative muscle fibers (muscle fibers built for steady energy use) and enhanced exercise endurance, essentially mimicking the effects of training without the actual workout.

Billon C, Sitaula S, Banerjee S, et al.

2024

A Synthetic ERR Agonist Alleviates Metabolic Syndrome

Mice with diet-induced obesity or genetic obesity showed impressive results: SLU-PP-332 increased energy expenditure (calories burned), boosted fat burning, reduced fat mass, and improved insulin sensitivity (how well cells respond to insulin). Importantly, these effects happened without reducing appetite or food intake.

Billon C, Schoepke E, Avdagic A, et al.

2024

The Estrogen Receptor-Related Orphan Receptors Regulate Autophagy through TFEB

ERR activation (the mechanism SLU-PP-332 uses; ERR stands for estrogen-related receptor) was found to regulate autophagy, the cellular cleanup process. This suggests additional anti-aging and cellular health benefits beyond just boosting metabolism (how the body uses energy).

Losby M, Hayes M, Valfort A, et al.

2026

Chemical optimization of the exercise mimetic SLU-PP-332 enables insight into estrogen-related receptor signaling

Medicinal-chemistry study of SLU-PP-332 analogues (close chemical relatives) (Int J Biol Macromol 2026; full text PMC13112601). Measured SLU-PP-332's kinetic solubility (how well it dissolves in water) at 0.2 μM in pH 7.4 phosphate-buffered saline (a salt water solution that mimics body fluids), which the authors describe as extremely low and consistent with its high cLogP (4.05; cLogP is a calculated measure of how fat-loving a molecule is). Several analogues kept comparable ERR activation with improved solubility or metabolic stability (resistance to being broken down).

Novel Pan-ERR Agonists Ameliorate Heart Failure Through Enhancing Cardiac Fatty Acid Metabolism and Mitochondrial Function

Mouse pressure-overload heart failure study (heart failure caused by making the heart pump against high pressure) (Circulation 2024; full text PMC10842599). SLU-PP-332 improved ejection fraction (the share of blood the heart pumps out with each beat), reduced fibrosis (scarring) and increased survival without affecting cardiac hypertrophy (thickening of the heart muscle). Methods: the powder was dissolved in DMSO (a solvent) as a stock, then diluted to 5 mg/mL in 12% DMSO and 15% Cremophor (another solvent) in PBS (salt water) and given by intraperitoneal injection (injection into the belly cavity) at 25 mg/kg twice daily.

Your questions

SLU-PP-332 FAQ

Is SLU-PP-332 actually a peptide?

Technically no—it's a small molecule compound, not a peptide made of amino acids. However, it's often grouped with peptides in the metabolic enhancement category because it targets similar goals and is used in similar research contexts. The 'PP' in its name stands for the chemical class, not peptide.

Can I really get exercise benefits without exercising?

Research shows SLU-PP-332 activates the same metabolic pathways as exercise—but here's the exciting part: it works even better when combined with actual exercise. The compound synergizes with training, so you get amplified results. Think of it as a metabolic booster that enhances whatever exercise you can do, or provides baseline benefits if you can't exercise at all.

Will this help me lose weight?

Mouse studies show significant fat mass reduction without changes in appetite or food intake. The weight loss comes from increased metabolism and fat burning, not from eating less. However, human studies are still needed, and results will vary based on diet, activity level, and individual factors.

How is this different from other metabolic compounds like Cardarine?

SLU-PP-332 works through ERR receptors (cell switches that control energy use), which are different from the PPAR-delta pathway that Cardarine targets. Both boost endurance and metabolism, but through different routes. Some researchers believe the ERR pathway may have a cleaner safety profile, though more human data is needed for both compounds.

Is this approved for human use?

No, SLU-PP-332 is currently a research compound and has not completed human clinical trials. It's available only for research purposes. The science is promising, but we're still in the early stages of understanding its effects in humans.

Why would someone use this instead of just exercising?

Great question! For healthy people who can exercise, the compound may enhance training results. But it's particularly interesting for people who can't exercise normally—those recovering from injuries, managing disabilities, dealing with conditions that limit physical activity, or elderly individuals at risk of muscle wasting.

Can I take this with other supplements?

Many users combine SLU-PP-332 with supplements that support the cell's energy-making parts, like CoQ10, L-Carnitine, or NAD+ precursors. However, be careful combining it with other strong metabolic compounds, diabetes medications, or stimulants. When in doubt, talk to a healthcare provider.

How long do the effects last after I stop taking it?

This is still being studied, but research suggests the metabolic changes (like more mitochondria (the power plants inside your cells) and more muscle fibers that burn oxygen for fuel) may last for some time after stopping. However, regular exercise and a healthy diet will be important for keeping the benefits long term.
