Dianabol is a synthetic steroid very similar in structure to testosterone. It is one of the oldest anabolic steroids on the illicit drug market. The anabolic properties of the drug were quickly realized soon after it was manufactured. It was first synthesized in 1958 at a time when the toxicity of steroids was not appreciated.
Infact, it was first marketed as a muscle growth agent and widely used in the 60s and 70s. Over the next decade, the drug proved to be a success for many athletes and bodybuilders, but soon the side effects of the drug became apparent.
All over the globe, bodybuilders complained of serious side effects and there were many cases of liver damage reported. Soon the drug acquired a bad reputation and in medicine its use only lasted a couple of decades. The drug was tried out as a treatment of infertility, muscle wasting and some resistant anemias. In the early 90s, the FDA finally banned the drug for use in humans. The drug is no longer manufactured anywhere in North America and most of Western Europe. The majority of Dianabol available today is manufactured in Mexico, SE Asia and China. The quality and purity of the preparations remain unknown.
