SLU-PP-332 is a err agonist ('exercise mimetic') used for endurance / fat loss. SLU-PP-332 is a small molecule, not a peptide, that activates ERR, a switch controlling how cells burn energy. In plain terms: it is nicknamed 'exercise in a molecule' because it pushes cells to act as if you had worked out, but it is very early with no human data.

How much water do I add to SLU-PP-332?

You can reconstitute SLU-PP-332 with 0.5, 1, or 2 mL of bacteriostatic water. Each option produces a different concentration and syringe draw for the same dose. Use the calculator to see which is easiest to measure.

What does SLU-PP-332 cost per dose?

Cost per dose depends on vial size, price paid, and your dose. Enter your vendor's price in the SLU-PP-332 calculator to see cost per dose and monthly cost.

What is the reference dose for SLU-PP-332?

The commonly referenced range is Research only, taken cycled. This is reference information, not a recommendation. Talk to a licensed clinician.

What are the side effects of SLU-PP-332?

Reported side effects of SLU-PP-332 include: There is no human data at all, and it is not a peptide.. Severity and frequency vary by person and dose.

Who should not take SLU-PP-332?

SLU-PP-332 is generally not appropriate for: No human safety data exists at all; Pregnancy. Talk to a licensed clinician before starting.

What is SLU-PP-332?

Plain language first. The technical label stays, but it never stands alone.

Overview

It is nicknamed exercise in a molecule, because it pushes cells to act as if you had worked out. It is very early, with no human data.

The technical version

SLU-PP-332 is a small molecule, not a peptide, that activates ERR, a switch controlling how cells burn energy.

What it's used for

People are interested in it for fat loss and endurance. It is very early, with no human data.

How does SLU-PP-332 work?

What it does in the body, and where.

SLU-PP-332 is a small molecule marketed as 'exercise in a pill'. That phrase is doing an enormous amount of work.

01
It activates ERR-alpha
A switch controlling how cells burn energy, which is also switched on by actual exercise.
02
Mice ran further and burned more fat
The finding behind the nickname.
03
It has never been given to a human
Not a single clinical trial. The doses circulating online are extrapolated from mouse studies by people on forums, not derived from any human research.

Pathway

A schematic of the compound's mechanism, not a diagnostic image.

What else is it used for?

Each use below carries its own evidence level. Approved means regulators have cleared it for that purpose. Investigational means it is in trials. Early research means it is being studied and is not established.

Evidence

Research only

How much, and do you cycle it?

The range, and whether you take breaks.

Research only, cycled. Commonly cycledCommunity practice

Cycled by convention rather than to a tested schedule. No published study establishes a block length or a break length for this one.

How long does it stay in the body?

The half-life, and where the figure comes from.

Nothing publishedNo figure

Nothing published. SLU-PP-332 is a small molecule rather than a peptide and the work on it is in mice.

You can compare this against the whole library to see where it sits.

How do I dose and price it?

Enter your vial and your dose. Pick a mix. We show the draw and the cost.

The vial holds a fixed amount of drug. Adding more water does not make more drug, it just spreads it thinner, so you draw a bigger number on the syringe for the same dose.

What it costs

SLU-PP-332 starts at $25.00 across 30 vendors, typically $5.00 – $32.00 per mg.

40 listings, last read Sep 5, 2026. Shipping and card fees are not included.

How do you store it?

Before mixing, and after.

Dry powder in the freezer or fridge. Once mixed, fridge, and use within about a month.

Unmixed lyophilized SLU-PP-332 keeps for a long time cold. Once you add water the clock starts: most reconstituted vials hold up for roughly 28 to 30 days at fridge temperature. Keep it out of light, and do not freeze it after mixing.

What are the side effects and cautions?

Known cautions and warnings for this compound.

Who should avoid it

Check these before anything else.

Common effects

Expected, and usually mild.

Unknown in humans. It has only been studied in rodents

Where this page says nothing is established, that means nobody has studied it, not that a compound is safe.

Is SLU-PP-332 approved?

And where the numbers on this page come from.

No. SLU-PP-332 is not approved for any use, anywhere. It is sold labelled for laboratory research only, and there is no legal route to buy it for human use.
