Compare GLP-1-related references by regulatory position
Begin with the distinction between a labeled approved product, a proposed compounded preparation and an investigational substance. Semaglutide salt identity and tirzepatide preparation details need separate checks; neither establishes an automatic substitute for the other.
Make the comparison specific
FDA says retatrutide and cagrilintide cannot be used in compounding under federal law. A blend or spray label does not remove an ingredient restriction. Record exact ingredients, concentration and presentation before comparing any reference estimate.
