Enforcement Actions and Their Impact

The FDA's enforcement efforts are multifaceted. In October 2025, the agency reportedly sent over 50 warning letters to GLP-1 drug compounders and manufacturers. This surge in WARNING letters, with over 100 issued by September 16, 2025, signifies a proactive strategy to curb regulatory non-compliance. Furthermore, the FDA has issued import alerts designed to halt the importation of potentially dangerous GLP-1 peptides, demonstrating a commitment to safeguarding public health.
