The common dose for Dianabol is 30-50mg each day , with a cycle that would usually last between 4 and 6 weeks . 30-40mg would be an effective dose for a person that is new to Dianabol, resulting in great gains in muscle mass and strength, whilst restricting possible side effects. More experience users may wish to take a slightly higher dosage, although like most other compounds, there is a dosage level where the muscle and strength gains plateau off and the side effects heighten, resulting in a point in which it is not worth increasing the dosage. Most experienced users will rarely take a dosage over 70-80mg per day.
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 . 
If you implement a Dianabol cycle, there is a crucial factor you need to understand. While Dbol is one powerful anabolic steroid , it is not a magical pill. If you supplement with Dianabol, it’s not going to automatically make you big. Granted, your strength will go up, but how big you get will be dependent on one thing and one thing only; food. If you do not eat enough to meet your growth needs, you’re not going to grow. Conversely, if you do eat enough to grow and you add in Dianabol, you will grow more than you would have otherwise. This isn’t rocket science, but for some reason, it is a concept lost on most. It is also necessary to note, if you are running a Dianabol cycle this does not mean you should eat like a pig. If you gorge and eat as if there’s no end in sight, Dbol or not you’re going to get fat. The rules of nutrition do not change just because you’re supplementing with anabolic steroids.
