Frequently asked questions

Is retatrutide FDA-approved?
No. Retatrutide is investigational and is not FDA-approved for weight loss. The FDA has warned about unapproved products containing retatrutide falsely marketed online.
Can I buy retatrutide online?
Retatrutide is not commercially available as an approved medication. Avoid websites selling “research” retatrutide for human use — these are not legitimate pharmacy products.
How does retatrutide differ from tirzepatide?
Retatrutide is an investigational triple-agonist studied in the TRIUMPH trials; tirzepatide is a dual agonist. Early research is promising, but retatrutide remains investigational and should not be framed as commercially available.
What GLP-1 options are available now?
Approved and compounded semaglutide and tirzepatide programs are available through licensed telehealth providers. Compounded semaglutide and compounded tirzepatide are not FDA-approved finished drug products. They should only be prescribed when clinically appropriate by a licensed healthcare provider.
