How to Find Retatrutide Clinical Trials in the US (and Questions to Ask)

ByGLP1-Consultant

Retatrutide is an investigational medication (not FDA-approved as of this writing). That means the only lawful way to receive “study retatrutide” is through a legitimate clinical trial.

This guide helps you:

  • find retatrutide trials in the United States using ClinicalTrials.gov,
  • understand what you’re looking at,
  • contact sites effectively,
  • ask the right questions before you consent,
  • spot scams,
  • and use a practical informed consent checklist.

Educational only, not medical advice. Discuss trial participation with your clinician.

Short answer (quick path)

  1. Go to ClinicalTrials.gov and search: retatrutide (also try LY3437943).
  2. Filter to:
    • Country: United States
    • Recruitment status: Recruiting / Not yet recruiting
    • Study type: Interventional (clinical trial)
  3. Open a study record and check:
    • sponsor,
    • contacts/locations,
    • eligibility criteria.
  4. Contact 2–6 nearby sites directly using the official contact info.
  5. During screening, ask about placebo odds, visit schedule, exclusions, costs/compensation, and what happens if you withdraw.
  6. Avoid anything that looks like: pay-to-enroll, medication shipping without consent, crypto payments, “DM for a link,” or “research peptide” sales.

The safest place to start: ClinicalTrials.gov

ClinicalTrials.gov is maintained by the U.S. National Library of Medicine (NIH). It’s the most reliable public index to identify real trials and see official contact info.
