Tirzepatide: what it is, its legal status and the evidence
The dual GIP and GLP-1 drug sold as Mounjaro and Zepbound, prescribed for type 2 diabetes and weight management.
What the evidence shows
Randomized trials, including two head-to-head trials against semaglutide, support its approved uses.

Legal and FDA status
Same shape as semaglutide: approved products exist, so the constraint is the copies rule rather than the bulks list, and the shortage that permitted broad compounding has ended.
Anti-doping status
NOT prohibited. In 2026 WADA clarified that its urine monitoring of semaglutide also includes tirzepatide. Both GLP-1 drugs remain in the Monitoring Program — surveillance, not a ban. Monitoring status can change, so check the live List.
