Is Retatrutide Safe?
Pending medical review
Short answer: Nobody can say for sure yet. Retatrutide is still being tested and is not FDA approved. In an early test, the most common problems were stomach problems, mostly mild to medium. "Research" retatrutide sold online is of unknown quality, the FDA says.
What early tests found
- Stomach problems like feeling sick were most common.
- Heart rate went up with higher doses, then came down after 24 weeks.
Online "research" retatrutide
In 2026 the FDA sent warning letters to several sellers of retatrutide labeled "research use only". See our warning letters tracker.
