How It Works
If properly compounded, it works identically to brand-name tirzepatide (Mounjaro/Zepbound). The same quality concerns apply as with compounded semaglutide — potency, sterility, and stability may vary significantly.
Mechanism: Compounded tirzepatide is the same molecule as Mounjaro/Zepbound, produced by compounding pharmacies. As of early April 2026, tirzepatide REMAINS on the FDA shortage list, meaning compounding is still broadly legal for both 503A and 503B pharmacies. However, Eli Lilly has pursued legal action against some compounders, and the regulatory landscape remains uncertain.
Who It's For
Indication
Used for weight loss and diabetes (off-label compounded use)
Patients currently on compounded tirzepatide should monitor the regulatory situation. Tirzepatide remains on the FDA shortage list (as of April 2026), but Lilly litigation and potential shortage list changes create uncertainty. Consider planning a transition to FDA-approved alternatives (Zepbound, Mounjaro, or Foundayo). Not recommended for new patients.
