Ok, let’s start off this article by saying that everyone knows that anabolic steroids produce incredible muscle growth and bodybuilding results fast. The best bodybuilding supplements then would in fact exhibit similar characteristics of anabolic steroids. However, everyone knows that they are illegal for use and distribution in the United States due to the Anabolic Steroid Control Act of 2004. Interestingly, included in this law were some very potent designer anabolic steroids, that were up until that time, sold legally as bodybuilding supplements. Ingredients such as Androstenedione that converted into testosterone in the body was made popular by Mark Mcquire when he broke the home run record, as a bottle was seen by a reporter in his locker. Norandrostenedione, which converted directly into nortestosterone in the body, was also sold at this time. By the way, Nortestosterone is better known as Deca Durabolin or chemically known as nandrolone. So, as you can see, there have been many attempts to sell products that worked like steroids, or that were actually in fact real steroids, through the years in the field of bodybuilding supplements.
