U.S. Customs and Border Protection officers at the Port of Cincinnati announced on Mar. 31 that they intercepted a scheme to smuggle more than 5,000 shipments of unapproved peptides into the United States from China.
The seizures highlight concerns about public health risks associated with unauthorized drugs entering the country. Authorities said these peptides are often used in weight loss injectables and other health-related treatments but may pose dangers when sourced from overseas vendors without proper certification.
According to officials, all seized packages between December and March 25 were misrepresented as containing other items. The shipments arrived in large cartons filled with smaller, unlabeled packages that were already labeled for their intended recipients. Cincinnati CBP officers identified over 300 such master carton attempts, each concealing about 15 individual peptide shipments.
"CBP officers in Cincinnati work tirelessly to combat the importation of unapproved shipments of goods such as these peptides used in weight loss injectables," said Cincinnati Port Director Eric Zizelman. "Noncertified or unlicensed chemicals originating from other countries and shipped into the United States presents a serious health risk to those who use them. CBP urges consumers to not gamble their health against the efficacy of prescription medicines they purchase online from overseas vendors."
The confiscated substances included active ingredients for Glucagon-like peptide-1 (GLP-1) medications like retatrutide, semaglutide, tirzepatide, as well as other prohibited peptides such as MOTS-C, TB10, semax, and cagrilintide. These products are regulated by the U.S. Food and Drug Administration (FDA) and should only be prescribed by doctors.
Authorities warned that imported drugs must meet FDA standards for quality and safety because products manufactured abroad might lack proper oversight or could be contaminated with dangerous substances or bacteria.
CBP works closely with the FDA to prevent illegal medications from entering U.S. markets and encourages consumers to ensure any purchases comply with state and federal regulations.
