Compounded tirzepatide has quickly become one of the most popular physician-guided treatments for medical weight management. But one of the most common questions patients ask is:
“How long does compounded tirzepatide last — and how should I store it properly?”
Proper storage plays a critical role in maintaining medication potency, safety, and treatment results. Because tirzepatide is a peptide-based medication, it is sensitive to temperature, light, and handling conditions.
Here’s everything you need to know.
Unlike commercially manufactured medications, compounded medications do not carry traditional manufacturer expiration dates.
Instead, compounding pharmacies assign what’s called a:
The Beyond-Use Date is the timeframe during which the medication is guaranteed to remain sterile and effective when stored correctly.
Most compounded tirzepatide prescriptions have a:
When continuously refrigerated, compounded tirzepatide generally maintains stability throughout this assigned period.
👉 Always follow the date printed on your pharmacy label, as this overrides general storage timelines.
Tirzepatide is a protein-based medication. Heat exposure can cause molecular breakdown, reducing effectiveness.
Store compounded tirzepatide at:
36°F to 46°F (2°C to 8°C)
Best practices include:

Freezing can permanently damage the peptide structure.
