- Sizes on sale
- Suppliers on this page sell SLU-PP-332 in 250 mcg, 300 mcg, 500 mcg, 1 mg, 2 mg, 5 mg, 10 mg, 20 mg and 50 mg vials. Some also sell packs of 2 to 60 vials, compared per mg of the whole pack rather than against single vials. Other forms on sale (kit, capsules, liquid and blend) are different products and are not compared per mg with vials. How prices are compared

- 1 of 74 suppliers have one for SLU-PP-332 on file with us
- Legal status in the US
- The FDA treats research peptides sold for human use as unapproved new drugs and has said in 2026 warning letters that research-use-only labels do not change that. Full summary with sources
What SLU-PP-332 is
SLU-PP-332 is a synthetic small molecule, not a peptide, that switches on the estrogen-related receptors (ERRα, ERRβ and ERRγ), proteins that control energy production in muscle and heart. In mice it increased endurance, raised energy expenditure and reduced fat, which is why it is called an “exercise mimetic”. It has never been tested in people, it is not an approved medicine, and its developers describe it as poorly absorbed when taken by mouth.

Before you choose a SLU-PP-332 supplier
Price per mg is only half the comparison. Check that the supplier publishes a certificate of analysis for the batch it is selling, ideally from an independent laboratory, and that the certificate confirms identity as well as purity: our guide on how to read a COA shows what to look for. A price far below the rest of the list is more often a warning than a bargain; peptide prices explained sets out why.
For what SLU-PP-332 is and what published studies have found, see our SLU-PP-332 guide. Handling questions are covered in how to store peptides, and the peptide calculator converts a vial size and water volume into concentration and syringe units.

Checking a SLU-PP-332 certificate of analysis
- The certificate names a laboratory you can find independently, and ideally one with no stake in the result.
- It carries a batch or lot number that matches the product page or the vial label, and a test date.
- It confirms identity by mass spectrometry, not only purity by HPLC. Purity alone does not show the vial contains SLU-PP-332.
- It includes the chromatogram and mass spectrum, not just a summary table.
- Where the laboratory offers online verification of its reports, the report number checks out.
Red flags
- No certificates at all, or certificates available only “on request”.
- The same certificate used for several products or several years of stock.
- Payment only by cryptocurrency or bank transfer, with a discount for paying that way.
- A price far below every other supplier on this page.
- No way to contact the store other than a web form.
- Vials labelled only with a code rather than the product name and strength.

Vials, capsules and pre-mixed products
Most research peptides are sold as freeze-dried (lyophilised) powder in sealed vials, which is mixed with a diluent such as bacteriostatic water before use in the lab. Some suppliers also sell pre-mixed solutions, nasal sprays or capsules under the same name. These are different products with different stability and dosing, so compare price per mg only between the same form, and check which form a listing is before comparing it with the rest of the table.
How this list is built: suppliers appear because they list SLU-PP-332 on their own website, read by our catalogue checks; nobody pays to be included or to move up. Ranking is by PepFinder Score, with stores that have nothing on sale after those that do. Prices, sizes and stock are as each site listed them when checked and may have changed.
