What Happened to Apex Peptides? Searches and Closure Questions

Editorial date correction: The published date reflects the earliest verifiable site record, September 25, 2026. Earlier displayed dates were not verified.

Apex Peptides’ website carried a temporary closure notice and just one listed product when Sioux City television station KCAU 9 reported on it September 24. Federal agents had searched an Apex Waste Management warehouse and a Dakota Dunes home the day before. Business filings reviewed by KTIV list the same primary Sergeant Bluff address for Apex Peptides and Apex Waste Management, explaining why the warehouse search enters the storefront story.

Why a waste warehouse appears in the peptide story

The searched warehouse stood at 503 Prosperity Way in North Sioux City, South Dakota, not at the shared primary address in Sergeant Bluff, Iowa. KTIV’s filing review also lists Apex Research at that Sergeant Bluff address and identifies Riley Isaacson as president of the waste-management and research businesses. Property records reviewed by the station identify the owner of the searched Dakota Dunes home as his twin brother, Ryan. A shared filing address connects business names; it does not identify what investigators sought at either property.

At the warehouse, agents carried out papers, boxes and a tote of small packaged items. Postal inspectors removed bags and boxes from the home. KCAU described the warehouse as one of three searched properties; the local accounts identify the warehouse and home, but do not name a third property or a separately searched Apex Peptides facility.

What officials said

The U.S. Postal Inspection Service led the searches, with the FBI, IRS criminal investigators and local law enforcement participating, KTIV reported. Postal inspector Travis Fondow told local radio station KSCJ that agents had visited multiple Sioux City-area locations; he declined to elaborate while the investigation was active.

Workers returned; the storefront still showed a notice

On September 24, KCAU visited the waste-management warehouse in the morning and found employees back inside. They declined to discuss the search. In the same day’s report, KCAU described a temporary closure notice on Apex Peptides’ website and a catalog reduced to one product. The report does not say when the notice first appeared.
