Dosing

How muchdo I take?

Subcutaneous: A small injection into the fatty layer just under the skin — the same way insulin is given.

Bioavailability High — most of the dose reaches your bloodstream, just more gradually than an IV.

Standard Dose

500 mcg - 1 mg

Frequency

Once daily

Duration

8-12 weeks (research use)

No human trials exist; preclinical mice showed ERR-agonist exercise-mimetic and metabolic effects [1][2]. Dose shown is the range used in the research/biohacking community, not a validated human dose.

Timing

Best time to take

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 food?

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

If stacking

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.

Administration

How do Iuse it?

Reconstitution

What you need

•Bacteriostatic water (if using injectable form)

•Insulin syringes (29-31 gauge) for injection

•Alcohol swabs for cleaning

•Oral tablets/capsules don't require reconstitution

Example

For injectable form: If you have a 10mg vial and add 2mL of bacteriostatic water, you get 5mg/mL concentration. Each 0.1mL (10 units) equals 500mcg of SLU-PP-332.

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

Injection

Route

Subcutaneous injection (just under the skin) or oral administration—oral is the preferred and more researched route

Best sites

•Belly fat area (2 inches from navel)

•Front or outer thigh

•Back of upper arm

Technique

1.Wash hands thoroughly with soap and water

2.Clean injection site with alcohol swab, let air dry

3.Pinch about an inch of skin

4.Insert needle at 45-90 degree angle

5.Push plunger slowly and steadily

6.Wait 5 seconds, then remove needle and apply light pressure

Storage

Before reconstitution

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 reconstitution

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 of degradation

Discoloration or yellowing of powder/solution

Cloudy appearance (solution should be clear)

Unusual odor

Clumping or crystallization of powder

Sample Daily Schedule

Morning (6-9 AM)

250-500 mcg injection

Site: Oral or subcutaneous (belly area)

Morning dosing aligns with natural cortisol rhythm and metabolic activation. If exercising, take 30-60 minutes before for potential synergistic effects.

Early afternoon (12-2 PM, if splitting dose)

Site: Oral or rotate injection site

Second dose can help maintain consistent blood levels. Avoid dosing late in the day to prevent any potential impact on sleep.

While preclinical results are encouraging, large-scale human clinical trials have not yet been completed. Always work with a healthcare provider when considering research compounds.

Common Side Effects

Experienced by some users

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.

Management: 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 become more active. This is actually the compound working as intended.

Management: 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.

Management: Stay well-hydrated. This effect is usually mild and indicates the compound is activating metabolic pathways.

Less Common

•Changes in appetite

•Mild headache

These typically resolve with continued use or dose adjustment.

Stop and Seek Help If

×Any signs of allergic reaction—stop immediately

×Persistent GI issues that don't improve with dose adjustment

×Significant changes in heart rate or blood pressure

×Sleep problems that persist beyond the first week

×Any side effect that feels concerning or unusual

×Your research protocol or cycle is complete

•Diet undermining results—you can't out-metabolize a terrible diet

•Unrealistic expectations—this isn't a magic pill, it's a metabolic enhancer that requires patience

Key Research

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

Billon C, Sitaula S, Banerjee S, et al., 2023

Finding: This foundational study showed that SLU-PP-332 increases mitochondrial function and cellular respiration in muscle cells. When given to mice, it boosted oxidative muscle fibers and enhanced exercise endurance—essentially mimicking the effects of training without the actual workout.

[2]"A Synthetic ERR Agonist Alleviates Metabolic Syndrome"

Billon C, Schoepke E, Avdagic A, et al., 2024

Finding: Mice with diet-induced obesity or genetic obesity showed impressive results: SLU-PP-332 increased energy expenditure, boosted fat burning, reduced fat mass, and improved insulin sensitivity. Importantly, these effects happened without reducing appetite or food intake.

[3]"An orally active estrogen receptor-related receptor agonist, SLU-PP-915, enhances aerobic exercise capacity"

Billon C, Appourchaux K, Côté I, et al., 2025

Finding: This study introduced an improved version (SLU-PP-915) that works when taken orally. It enhanced exercise performance and synergized with actual exercise training—meaning the compound and physical training together produced better results than either alone.

[4]"The Estrogen Receptor-Related Orphan Receptors Regulate Autophagy through TFEB"

Losby M, Hayes M, Valfort A, et al., 2024

Finding: ERR activation (the mechanism SLU-PP-332 uses) was found to regulate autophagy—the cellular cleanup process. This suggests additional anti-aging and cellular health benefits beyond just metabolic enhancement.
