Retatrutide:
what we're watching.

Retatrutide is one of the most closely watched investigational medications in metabolic health. It is currently in clinical trials and is not FDA-approved and not available to prescribe. Here's an honest look at what it is and where it stands, so you can follow the science with us.

The basics

What is retatrutide?

Retatrutide is an investigational triple-agonist — it targets three receptors involved in metabolism (GLP-1, GIP, and glucagon), where current medications like semaglutide target one and tirzepatide target two. In published Phase 2 research it has drawn significant attention in the medical and metabolic-health community. It is sometimes informally called a "GLP-3," though that term isn't technically accurate.

Because it is still being studied, no licensed provider or pharmacy can legally prescribe or compound it today. Any source claiming to sell "retatrutide" now is operating outside the law — a real safety risk we'd urge you to avoid.

The road to approval

Where it stands in the process

The stages below reflect the general FDA drug-approval pathway and widely reported industry expectations — not a Vincera timeline or a promise of availability. Dates are estimates that can and do change.

Phase 1 & 2 · Complete
Early trials
Initial safety and dose-finding studies completed, with results published in peer-reviewed journals that generated significant interest in the metabolic-health field.
Phase 3 · Underway
Large-scale clinical trials
The manufacturer is conducting large Phase 3 trials to confirm safety and effectiveness across thousands of participants — the stage that generates the evidence the FDA reviews.
Reported through 2026–2027
FDA Review · Not yet begun
Regulatory submission & review
If trials succeed, the manufacturer would submit an application and the FDA would review it. Approval is never guaranteed and timing depends on the data and the agency.
Industry estimates: 2027+
If & when approved
Availability to patients
Only after FDA approval could any licensed provider evaluate it for appropriate patients. We'll share accurate updates here as the science and regulations develop.
