How the hunger for a new weight loss drug is feeding an industry of fakes

Illicit and potentially dangerous counterfeit versions of the experimental weight-loss drug retatrutide are being sold on the black market. Experts warn that these unapproved substances pose significant health risks as they bypass regulatory safety testing.
Why it matters

Excitement around the creation of a new drug, especially one showing early promise in clinical trials, is often celebrated by those developing it.

The jab has not yet been approved for human use by any regulatory body.
