Compounded tirzepatide from licensed 503A pharmacies using FDA-approved API is widely considered safe by clinicians, though it carries less manufacturing oversight than brand-name Zepbound. Risks include variable potency, contamination, and use of unapproved salt forms by lower-quality compounders. Following the FDA resolution of the tirzepatide shortage in October 2024, compounding pathways have tightened. Verify your clinic uses an FDA-registered 503A pharmacy with FDA-approved API.
