What is compounded tirzepatide?

A pharmacy-prepared version of tirzepatide that is not FDA-approved and not the same as Zepbound or Mounjaro.

Compounded tirzepatide is prepared by a licensed pharmacy. It is not FDA-approved and not the same as Zepbound or Mounjaro. Quality depends on the pharmacy; many products are multi-dose vials requiring careful self-measurement. With the shortage resolved, lawful compounding is now narrow.

Compounded GLP-1 in 2026

The FDA resolved the tirzepatide (Dec 2024) and semaglutide (Feb 2025) shortages, and wind-down deadlines passed in 2025. On Apr 30, 2026 the FDA proposed excluding these drugs from the 503B bulks list (comment closed Jun 29, 2026). Patient-specific 503A compounding continues only narrowly, and cost alone is not a clinical need. Full regulatory status →
