Unapproved Drug Sold Illegally for Weight Loss
23 Jan
Summary
- Unapproved weight-loss drug Retatrutide is sold illegally online.
- Suppliers claim the drug is for 'research' but ship to homes.
- Users risk serious side effects from untested, counterfeit products.

Australians are acquiring the experimental weight-loss drug Retatrutide through illicit online channels. Suppliers deceptively label the product as "for research use only" while shipping it directly to consumers' homes, often with guidance from fitness influencers.
This peptide, still in phase 3 clinical trials by Eli Lilly, has not received regulatory approval anywhere worldwide. Pharmacologists express serious concerns, highlighting that the drug's safety and long-term effects remain unknown. The unregulated nature of these online sales means users inject potentially dangerous, non-pharmaceutical-grade substances.
Risks include severe side effects similar to approved GLP1 agonists, such as gastrointestinal issues, pancreatitis, and dangerous rapid weight loss. Furthermore, improperly folded peptides can trigger adverse immune responses, including anaphylaxis. The US Food and Drug Administration has also flagged similar illegal sales practices.
