For most men, a dianabol cycle will last 6-8 weeks with 6 weeks being the most common; 8 weeks can be well-tolerated, but you must keep in mind the hepatotoxic nature of the hormone. Further, after 8 weeks, it's highly unlikely the steroid is going to keep providing the same kind of gains unless you up the dose, and that's not a responsible plan; you're better off working your Dbol in and out through various phases of use. In any case, most men will find 20mg per day to be the minimal dosing for a performance benefit with 30mg per day being far more common. If the hormone is tolerated well at these doses, most men will find they can handle 50mg per day, but you'll want to make sure you can handle a lower dose your first go around. Very few men will ever have a need to go above 50mg per day, and to be honest, if you can't grow substantially on 50mg of dianabol a day your hormones are either fake or something is wrong with the way you eat and train, and we mean horribly wrong.
