Methandienone (also known as methandrostenolone, Dbol, dianabol) is an orally-effective anabolic steroid originally developed in Germany and released in the US in the early 1960s by Ciba Specialty Chemicals. This is a derivative from testosterone, one of the most popular steroid compounds in the world and the second steroid (after testosterone) ever produced. Methandienone promotes dramatic increases in protein synthesis, glycogenolysis, and muscle strength over a short space of time.
The most commonly used AAS in medicine are testosterone and its various esters (but most commonly testosterone undecanoate , testosterone enanthate , testosterone cypionate , and testosterone propionate ),  nandrolone esters (most commonly nandrolone decanoate and nandrolone phenylpropionate ), stanozolol , and metandienone (methandrostenolone).  Others also available and used commonly but to a lesser extent include methyltestosterone , oxandrolone , mesterolone , and oxymetholone , as well as drostanolone propionate , metenolone (methylandrostenolone), and fluoxymesterone .  Dihydrotestosterone (DHT; androstanolone, stanolone) and its esters are also notable, although they are not widely used in medicine.  Boldenone undecylenate and trenbolone acetate are used in veterinary medicine . 
Prior to progressing on this topic, it is important to note that Dianabol is not for individuals who do not want to gain extra water weight. Nevertheless, it is one of the best legal steroids because it causes very little water retention if used moderately. Retaining very little fluid will make you appear smoother offering a very natural look to your entire body. Therefore, it can rightly be concluded that Dianabol users look epic while holding very little water. It is also important to note that weight gained with the use of dianabol will appear in the form of lean muscles.
