Your protocol

How SLU-PP-332 is prescribed.

Who it's for
  • Adults working on fat loss who want to get more out of the training they already do
  • People building endurance who want support at the cellular level
  • Patients who understand the evidence is from animal studies and are comfortable with that
  • Anyone who wants a metabolic option that is not a hormone

Your physician decides whether SLU-PP-332 is appropriate for you after reviewing your intake and labs.

Directions & duration

Inject 0.25 mL (25 units) subcutaneously once daily Monday through Friday.

Cycle. One small injection each day, Monday through Friday. Ongoing monthly treatment; your physician adjusts the dose as your goals evolve.
Directions shown are the pharmacy's standard for this preparation. Your prescription label is the final word.
What's included
  • Licensed physician review of your intake, history, and labs
  • Medication compounded to your prescription by a PCAB-accredited, FDA-registered pharmacy
  • Every batch independently tested before release
  • Sterile syringes and alcohol prep pads for injectables
  • Tracked delivery to your door, refills on schedule
  • Message your physician anytime; dose changes without an appointment
Storage & handling
  • Store refrigerated (36–46°F / 2–8°C) at all times, including before first use.
  • One vial is your monthly supply. A fresh vial ships every 28 days on your refill schedule, so you're always well inside the beyond-use date on your label.
  • Protect from light. Wipe the stopper with an alcohol pad before every draw.
  • Dispose of syringes in the sharps container per the included instructions.
What to expect

A typical course of SLU-PP-332.

TimeframeWhat patients commonly report
Weeks 1–2Steadier energy and a calmer appetite are the earliest reports. Redness at the injection site is normal.
Weeks 3–8Easier fat loss and better stamina are what patients report most in this window.
OngoingLong-term treatment. Refills ship every 28 days, and your physician adjusts the dose over time as your goals evolve.
Individual results vary. Compounded medications are not FDA-approved; a licensed physician determines whether treatment is appropriate and monitors your progress.

The science

How SLU-PP-332 works, and what the research shows.

How it works

Endurance exercise flips a switch in muscle cells that builds more mitochondria and burns more fat for fuel.

SLU-PP-332 flips that same switch directly, which is why it is called an exercise mimetic.

Clinical evidence
  • Rodent studies reported more endurance, more fat burned and less weight gained on a high-fat diet.

  • There are no published human trials.
