Selected passages from the FDA letter
Quoted FDA text from the published dataset. These selected excerpts are not the complete letter.
Passage 1There are no FDA-approved applications on file for your compounded retatrutide drug products. Under sections 505(a) and 301(d) of the FDCA [21 U.S.C. §§ 355(a) and 331(d)] a new drug may not be introduced into or delivered for introduction into interstate commerce unless an application approved by FDA under section 505 of the FDCA is in effect for the drug.
Passage 2Furthermore, your compounded retatrutide drug products are intended for conditions not amenable to self-diagnosis and treatment by individuals who are not medical practitioners; therefore, adequate directions for use cannot be written so that a layman can use these products safely for their intended use. Consequently, their labeling fails to bear adequate directions for their intended use causing them to be misbranded under section 502(f)(1) of the FDCA.
Passage 3Compounded drug products are not FDA-approved. Your claims imply that your products are the same as an FDA-approved product when they are not. As a result, these claims are false or misleading and your products are therefore misbranded under sections 502(a) and 502(bb) of the FDCA [21 U.S.C. §§ 352(a) and (bb)].
