According to the DOJ, USP Labs in Texas imported bulk isolated chemical ingredients from China, then mislabeled them as plant-based ingredients. They also engaged in deceptive marketing and even the chemical adulteration of their product, says the DOJ, causing liver damage in numerous customers and putting hundreds of thousands of people at risk.

In a widely publicized announcement today, the DOJ, FDA, FTC and DoD all urged consumers to beware of what they call "high risk supplements" which are:

• Weight loss dietary supplements made with chemical stimulants and marketed with outrageous claims of magical weight loss.

• Bodybuilding supplements made with chemical ingredients that promise unreal muscle gains but actually contain potentially hazardous chemicals.

• Performance-enhancing supplements that may contain banned substances (doping) which may also pose a risk to consumers.
