Compounding Pharmacies

Licensed pharmacies specializing in sterile peptide compounding (Section 503A or 503B). These facilities manufacture patient-specific or clinical-grade peptides under strict state and federal oversight. Compounding pharmacies operate under USP <797> and <795> standards for sterile and non-sterile preparations respectively, with 503B outsourcing facilities additionally subject to FDA cGMP inspection. FDA enforcement activity in 2024-2025 has intensively targeted unlicensed peptide compounding, particularly around GLP-1 products such as semaglutide and tirzepatide, with over 50 warning letters issued in September 2025 alone to compounders making unauthorized therapeutic claims.
