These actions primarily target companies involved in the compounding and marketing of GLP-1 receptor agonists and other peptides, signaling a stricter regulatory environment for these rapidly evolving therapeutic agents.

In September 2025, the FDA issued over 50 warning letters to companies for unlawfully marketing compounded GLP-1 products, with a particular focus on those presented as "generic" alternatives. This wave of enforcement, with many letters dated September 9, 2025, and a broader release of approximately 80 warning letters on September 16, 2025, underscores the agency's commitment to ensuring drug safety and efficacy. Eli Lilly and Company (Lilly), a major player in this space, also received an FDA warning letter on September 9, 2025, concerning a direct-to-consumer program.

Understanding the Violations:

The warning letters issued in September 2025 highlight several key areas of concern:

* Compounded Drug Products Under the FDCA: A primary focus is on compounded drug products that do not meet the conditions outlined in Sections 503A and 503B of the Federal Food, Drug, and Cosmetic Act (FDCA). This includes issues related to the appropriate use of compounding pharmacies and the types of substances that can be compounded.

* Failure to Meet Conditions of Sections 503A and 503B: Companies are being warned for not adhering to the specific requirements for compounding, such as the lack of a valid prescription for an individual patient or compounding from bulk drug substances that do not meet specific criteria.

* Marketing and Advertising: The FDA is cracking down on misleading advertising and promotion of peptide drugs. This includes claims made about efficacy, safety, and the availability of "generic" versions without proper regulatory approval. The agency's new policy, announced on September 16, 2025, aims to curb direct-to-consumer prescription drug advertising.
