Wistar Institute Develops Single-Injection Weight-Loss Drug Lasting 70 Days in Mice

Researchers at the Wistar Institute in Philadelphia report a novel method that turns the body into a self-producing factory for a weight-loss drug, with a single dose in mice lasting up to 70 days—roughly ten times longer than Ozempic. The findings are based on animal studies, and human efficacy and safety remain unproven. This could represent a significant advance in obesity treatment if replicated in clinical trials.
