What SLU-PP-332 does

SLU-PP-332 is a small molecule, not a peptide. It activates cell switches involved in energy use and improved endurance and fat metabolism in mice. No published study has dosed people, and no human trial was registered in this search. Oral absorption is poor in preclinical work. Human benefits, safe doses and long-term harms are unknown.

  • In mice, it increased how long they could run on a treadmill. (animal)
  • In mice with obesity, it reduced fat gain. (animal)
  • Some users report easier cardio or more training capacity, others no effect; no study has tested it in people. (Reported by users)

How to mix SLU-PP-332

Comes as: Community-reported capsules and tablets, Community-reported powder vials and injection mixtures, Community-reported sublingual liquids.

Mixed with: Users report bacteriostatic water with dimethyl sulfoxide (DMSO). No safe human injectable formulation or mixing method is established..

Common vial sizes: 3, 5, 10 mg. Common water amounts: 0.75, 2, 2.5 mL.

  • These are reported vial sizes and water volumes, not a validated mixing recipe. Frequency in the wider community is unknown.
  • SLU-PP-332 had kinetic solubility of only 0.2 micromolar in a lab assay. Ordinary peptide mixing assumptions do not apply.
  • Users report clouding and precipitate after adding water. Visual clarity cannot confirm uniform dose, identity, sterility or solvent safety.
  • DMSO percentages and mixing instructions conflict online. No safe subcutaneous DMSO limit was established in this research.
  • Published mouse studies used laboratory solvent mixtures for abdominal-cavity injections; that route is different from injection under the skin.

Before mixing: No validated human-product storage temperature or shelf life found. Capsule users ask about refrigeration; this is not stability evidence.

After mixing: No validated shelf life in bacteriostatic water, DMSO or combined solvents. Published mouse formulations do not establish home-vial stability.

SLU-PP-332 side effects and risks

Reported side effects

  • Sweating or feeling hot: community reports: Reported online; no measured incidence., moderate. Stop and seek assessment if overheating, weakness or confusion develops. (source)
  • Fatigue or brain fog: community reports: Reported during higher dosing and after stopping; rates and cause unknown., moderate. Persistent or disabling symptoms need clinical assessment. (source)
  • Trouble sleeping: community reports: No placebo controlled frequency estimate., moderate (source)
  • Injection pain or irritation: Reported online; product and solvent contributions unknown., moderate. Hot, swollen or spreading redness needs urgent assessment. (source)
  • Lightheadedness and glucose changes: Both high and low readings reported; one comment gave 2.6 mmol/L. No verified incidence., serious. Check glucose during symptoms; confusion or collapse needs emergency care. (source)
  • Reduced libido: isolated high-dose report: One poster escalated to 500 mg/day orally; hormone injury was not confirmed., moderate (source)
  • Menstrual or breast changes: isolated report: One female commenter; no hormone tests or causal confirmation., moderate (source)
  • Nausea during multi-drug use: One tesamorelin combination report; cause uncertain., moderate (source)

Interactions

  • Insulin: Insulin can cause low glucose. Added SLU-PP-332 effects and insulin-adjustment rules have not been studied in people.
  • Sulfonylureas: These drugs can cause low glucose. Added effects and dose-adjustment rules with SLU-PP-332 have not been studied in people.
  • GLP-1 drugs and retatrutide: No human combination trial found. Users report lightheadedness and variable glucose during multi-drug use.
  • Other ERR agonists: Same-target combinations have no human safety data. SLU-PP-915 is a different compound, not an oral version of SLU-PP-332.
  • BAM15 and other experimental metabolic drugs: Online combinations add unstudied metabolic effects; no protective or safe stacking schedule is known.
  • Piperine absorption boosters: Oil/piperine mixtures are proposed online to alter exposure. Neither absorption nor interaction risk has been measured in people.
  • Warfarin and other anticoagulants: No interaction data exist. This is an uncertainty screen for drugs where exposure changes or injection bleeding matter, not a proven drug interaction.

Product quality risks

  • Health Canada warns that unauthorized injectable drugs have not been assessed for safety, efficacy or quality. This is general product-risk evidence.
  • Wrong identity, wrong amount, microbial contamination and unsafe excipients are risks of unauthorized drugs; their frequency for SLU-PP-332 is unknown.
  • No independent retail-product survey or SLU-PP-332-specific poison-center dataset was found. Vendor certificates are not a substitute.
  • Powder purity does not establish dose per capsule/vial, solvent safety, sterility or endotoxin levels.
  • Cloudy or settled mixtures can have uncertain dose uniformity. A clear appearance also cannot prove injection quality.
