Each batch (or “lot”) of compounded tirzepatide prepared by the compounding pharmacy includes its own Certificate of Analysis (CoA). A CoA provides information about the testing performed on that specific lot. Because pharmacies receive new lots regularly, it is not possible to know in advance which lot will be used for your prescription.
For compounded sublingual tirzepatide, the pharmacy may use ingredients that are suitable for sterile-use compounding. If you have questions about the source materials or testing associated with your specific prescription, your pharmacy or healthcare provider can provide additional information.
