In the regulator’s own words
"Tirzepatide and semaglutide do not currently appear on the 503B bulks list or on FDA’s drug shortage list."
"For a state-licensed pharmacy or physician compounding, dispensing or distributing semaglutide injection products under section 503A of the FD&C Act, the period of enforcement discretion (described below) has ended."
"Compounded drugs are not FDA-approved. This means that FDA does not verify the safety, effectiveness or quality of compounded drugs before they are marketed."
