New York Nutrition Company / American Metabolix was cited for distributing unapproved new drugs and misbranded products, including Muscle Test, Banish, Ketogenic Diet Aid, and Keto Friendly Collagen, which made disease treatment and prevention claims (such as anti-cancer, sexual dysfunction, and breast cancer prevention) that classified them as drugs under federal law. The company also violated regulations by marketing Exile Euphoric Weight Loss, Exile Super Shock, Havok Hardcore, and Keto Pump products as adulterated drugs without FDA approval. The FDA's June 2021 website review identified these violations, and the warning letter was delivered via overnight mail in August 2021, requiring the company to cease introducing these products into interstate commerce for their claimed therapeutic uses.
