Editor's Note

Today's digest underscores the growing tension between peptide accessibility and safety. ProPublica published a major investigation warning that the FDA's reversal on 14 restricted peptides could flood the market with inadequately tested drugs — a concern punctuated by a federal indictment of a Utah physician who sold misbranded Chinese peptides to over 200 patients. On the clinical side, a randomized trial of semaglutide for major depression produced intriguing but inconclusive results: no improvement in executive function, but signals of benefit in global cognition. Meanwhile, the GLP-1 story continues to expand beyond metabolic disease, with a comprehensive NeurologyLive review mapping the repositioning of GLP-1 drugs for Alzheimer's, Parkinson's, and other neurological conditions. In the business arena, Noom's acquisition of Tailor Made Compounding signals that tech-wellness platforms are moving aggressively into peptide-based therapies, even as NBC News published a widely-read investigation questioning whether the peptide craze is outpacing the science.

Semaglutide Fails to Improve Executive Function in Depression but Shows Cognitive Signals

A 16-week randomized, double-blind trial of oral semaglutide in 72 adults with major depressive disorder found no improvement in executive function vs placebo. However, secondary analyses showed semaglutide improved global cognition and produced clinically significant weight loss, suggesting potential but unclear neuropsychiatric benefit.

NeurologyLive Review Maps GLP-1 Drug Repositioning for Alzheimer's, Parkinson's, and Beyond

A comprehensive NeurologyLive review details emerging evidence for GLP-1 receptor agonists across neurological diseases including Alzheimer's, Parkinson's, multiple sclerosis, and stroke. Despite setbacks in the Phase 3 EVOKE Alzheimer's trial, ongoing trials like LIGHT-MCI and OxSENSE continue to explore neurobiological mechanisms beyond metabolic effects.

Eli Lilly Loses Indian GLP-1 Market Share While Novo Nordisk Holds Steady After Generic Flood
