Citando:
"Most of the adulterated products, about 45 percent, were marketed for sexual enhancement, weight loss (about 41 percent) or muscle-building (12 percent). Drugs found in sexual enhancement products included sildenafil, tadalafil and vardenafil, all active ingredients in prescription medications intended for erectile dysfunction, which, when overused, can cause serious damage to the blood vessels.
The most common pharmaceutical ingredients detected in adulterated weight loss products were sibutramine, which was removed from the U.S. market in 2010 due to cardiovascular risks, and the laxative phenolphthalein. Many of the adulterated muscle building products contained undeclared anabolic steroids, which, when abused, can lead to mental problems in the short term and kidney problems, liver damage and heart problems in the long term."
