According to The Tan Sheet, some supplements contain prescription drugs that could be dangerous or get you busted during a drug test. In the past few years a significant number of weight lifters were caught for taking the banned anabolic steroid nandrolone, also known as Deca or Deca Durabolin. Those who are informed know that this particular anabolic steroid can stay in blood system for more than 6 months after stopping usage, mainly done for muscle building and weight gain purposes.
However, what was found in some of these cases was that these trainers took bodybuilding supplements contaminated (known as “spiking”) with small amounts of nandrolone. The Food and Drug Administration, also known as the FDA, announced that it plans to step up efforts to eliminate illegal ingredients in food supplements and enforce regulations against supplement makers who make unsubstantiated health claims for their products.
