Hong Kong Fushi Bioengineering

Hong Kong Fushi Bioengineering Co., Limited was a Hong Kong-based company primarily engaged in the production and marketing of dietary supplements and traditional herbal products. The company was best known for its male enhancement and weight loss supplements, which were distributed internationally under various brand names. However, the firm frequently appeared in public health advisories from agencies such as the U.S. Food and Drug Administration (FDA) due to the presence of undeclared synthetic pharmaceutical ingredients in its products. These products were often marketed as natural alternatives but contained substances like sildenafil or sibutramine. The company was officially incorporated in 2004 and dissolved in 2015. Its business model focused on commercial-scale distribution rather than proprietary drug discovery or clinical research.
