The short answer

Be very careful. Many are selling compounded copies whose legal basis ended when the drug shortages ended, and dosing mistakes have put people in the hospital.

During the shortages, pharmacies were allowed to compound semaglutide and tirzepatide. The FDA declared those shortages over in late 2024 and early 2025. Since then it has sent waves of warning letters to sellers and reported patients who injected five to twenty times the intended dose because they misread a multi-dose vial. Some products use salt forms of the drug that were never approved.

If you need one of these medicines, get the approved product through a physician who will check your labs, your muscle, and your plan for the long term. As for “lipotropic” and B12 “skinny shots,” no trial shows they cause fat loss.
