Some Nutritional Sports Supplements Contain Banned Substances Not Listed On Label

June 23, 2014: 12:00 AM EST
A study by Australian scientists shows that some sports-related nutritional supplements sold in that country contain banned substances – specifically androgens – not listed on labels. The undisclosed contents put the general public at risk along with athletes who would test positive for illegal substances. The researchers tested 79 nutritional supplements purchased randomly from Sydney-based stores. They included protein powders, amino acids, creatines, fat metabolizers, "testosterone-boosters”, carbohydrates and stimulant/nitric oxide "pre-workout"-based supplements. Six of the tested products were androgen-positive but androgen was not listed on the label.
