Compounded GLP-1 receptor agonists (semaglutide, tirzepatide) are widely marketed for weight loss in Colorado, but these products lack FDA approval for safety and efficacy, are often mislabeled as 'generic' or 'FDA-approved', and may contain unsafe additives like BPC-157 or unapproved salt forms.

Be aware that compounded GLP-1 drugs sold directly to consumers are not FDA-approved for safety or efficacy. They may contain impurities, incorrect doses, or unsafe additives like BPC-157. Marketing claims of 'FDA approval' or 'generic' status are misleading. Consult a healthcare provider to understand the risks and legal status of these products.

This study identified several instances of unapproved glucagon-like peptide-1 products being compounded and advertised in Colorado. Additionally, 1 product was advertised as compounded with BPC-157, a substance determined by the Food and Drug Administration to be unsafe for compounding. This study also identified numerous examples of misleading claims regarding the regulatory status of compounded glucagon-like peptide-1 products.
