In clinical practice they range from decades-old, life-saving hormones like insulin to blockbuster metabolic drugs like semaglutide — and, increasingly, to a class of unapproved "research" peptides whose regulatory status changed twice in 2026 alone. This guide synthesizes the mechanistic biology, evidence grading, approved indications, safety considerations, and — new for this update — a full breakdown of the FDA's July 2026 advisory-committee vote on compounded peptide access, decoded for both clinicians and patients. Quick Answer (AI & Search Summary) Peptides already underpin FDA-approved drugs like insulin and the GLP-1 agonists. A separate group of investiga...
