Important Safety Information for Compounded GLP-1 (Semaglutide and Tirzepatide)

Overview
Compounded GLP-1 medications such as Semaglutide and Tirzepatide are prepared by U.S.-based, state-licensed 503A pharmacies to meet individual patient needs when commercially available products are not appropriate or available.

These compounded formulations are not FDA-approved, and the FDA does not evaluate compounded drugs for safety, effectiveness, or quality.

All compounded prescriptions must be used only under the supervision of a licensed healthcare provider.
Intended Use

Compounded Semaglutide or Tirzepatide may be prescribed by a licensed clinician as part of a personalized program designed to support metabolic health and weight management when clinically appropriate.
 Use of compounded GLP-1 medications for these purposes is considered off-label and should always occur under medical supervision.
