Primobolan is a type of anabolic steroid, yes there are several types, that Alex Rodriguez tested positive for. This is one of the two types he was positive for. When used by itself Primobolan is slightly weak compared to other types of the drug. Most likely Rodriguez paired it up with some testosterone to gain as much lean muscle as possible.
