SLU-PP-332 – High Purity Research Molecule (200mg per capsule)

SLU-PP-332: What It Is and What to Check Before Buying

SLU-PP-332 is one of the most talked-about research compounds of the past two years, often described online as an “exercise mimetic.” Search results are crowded with supplier pages, and many of them blur the line between what has been shown in mice and what is being implied to human buyers. This guide covers what the compound is, what the research supports, what UK listings typically look like, and how to judge quality.

Research use only. SLU-PP-332 is sold for laboratory research. It is not a medicine, supplement or food, and it is not intended for human or veterinary use.

What Is SLU-PP-332?

SLU-PP-332 is a synthetic small molecule, not a peptide. That distinction matters for handling, solubility and storage, and many listings get it wrong by filing it alongside peptides. It acts as an agonist of the estrogen-related receptors ERRα, ERRβ and ERRγ, which are nuclear receptors that regulate genes involved in mitochondrial function and oxidative metabolism. Despite the name, they are distinct from the classic estrogen receptors.

Identifiers listed on supplier data sheets:

• Chemical name: (E)-4-Hydroxy-N’-(naphthalen-2-ylmethylene)benzohydrazide
• Alternative name: SR9861
• CAS number: 303760-60-3
• Molecular formula: C18H14N2O2
• Molecular weight: about 290.32 g/mol
• Class: pan-ERR agonist

What the Research Actually Shows

The interest comes from preclinical work, mostly in mice, reporting that ERR activation reproduced some molecular responses associated with aerobic exercise, including changes in mitochondrial activity, fatty-acid oxidation, energy expenditure and endurance measures. Cell-based studies have examined skeletal muscle and metabolic pathways in more detail.

Be precise about the limits. These are animal and cell-culture findings from a small number of research groups. No completed human trial has established safety, efficacy or a dose for SLU-PP-332. “Exercise mimetic” describes a molecular signalling pattern in experimental models. It does not mean the compound replaces exercise, and any page that says so is overstating the evidence.

SLU-PP-332 Price: What UK Listings Look Like

SLU-PP-332 price varies widely by format and supplier. As one reference point, Futureproof Peptides lists 250mcg capsules at £69.99. Your other competitors sell 500mcg capsules and a 100mg capsule format, so unit sizes are not directly comparable. I could not open those three pages, so check their current prices yourself before publishing any comparison.

When comparing, look at:

• Cost per milligram of active compound, not cost per bottle
• Whether batch testing is included and published
• Format: bulk powder, capsules or another presentation
• Stock accuracy: a listing that shows availability but cannot ship is worthless
• Shipping terms: tracked delivery and dispatch times

SLU-PP-332 for Sale: What to Check Before You Buy

When browsing SLU-PP-332 for sale listings, work through this checklist:

1. Batch-specific COA with HPLC purity and identity confirmation, matched to a lot number
2. Correct identifiers: CAS 303760-60-3, formula C18H14N2O2 and molecular weight near 290.32
3. Correct classification: a small molecule, not a peptide
4. Honest evidence framing: research language, with the absence of human data stated
5. A Safety Data Sheet for laboratory handling
6. No health, weight-loss or performance claims and no dosing guidance

SLU-PP-332 in UK: Sourcing and Compliance

Buying SLU-PP-332 in UK from a domestic supplier avoids customs delays and gives you a company you can verify. Look for a registered company number, a physical address and working contact details.

One point deserves particular care. Some UK listings sell SLU-PP-332 as pre-measured oral capsules in microgram strengths, and a few describe them as a “metabolic support supplement.” A pre-dosed capsule is a format designed for human consumption. Under UK law, a product marketed for human use that makes health or metabolic claims can fall under food-supplement, novel food or medicines rules, and a “research use only” line does not change what the product functionally is. If you are a buyer, treat that as a warning sign. If you are a seller, this is where regulatory risk concentrates.

Storage and Handling

• Store in a cool, dry place away from light and moisture, following the COA and SDS
• Use the solvent and handling procedure in your batch documentation
• Use standard laboratory risk controls, as with any uncharacterised compound
• Follow your institution’s validated protocols

Frequently Asked Questions

Is SLU-PP-332 a peptide?
No. It is a synthetic small molecule with a molecular weight of about 290 g/mol.

Has SLU-PP-332 been tested in humans?
No completed human trial exists. Published data comes from cell and animal studies.

Is SLU-PP-332 the same as SLU-PP-915?
No. They are related ERR agonists from the same research programme, but structurally different compounds with separate bodies of evidence.

Is it approved as a medicine or supplement in the UK?
No. It has no MHRA-approved medicinal status and is sold as a research chemical.

What should come with my order?
A labelled container with a lot number and access to the batch COA and SDS.

Final Thoughts

SLU-PP-332 has an interesting preclinical story, but the market around it runs well ahead of the evidence. Choose a supplier that documents identity and purity, classifies the compound correctly, and does not dress a research chemical up as a wellness product.
