After the Kefauver Harris Amendment was passed in 1962, the .

They are the two most common and popular oral steroids of all time and for the purpose of bulking there are few that can come close to the power of Dianabol and Anadrol . Both of these very powerful steroids are often discussed together and in many circles you will find fans of both and often fans of Anadrol will swear up and down it is the more powerful of the two; however, this is simply not true. On a milligram for milligram basis Dianabol is far stronger than Anadrol; in-fact, its not that close; yes, both are very powerful but Dianabol takes first prize handedly. This common misconception regarding the two steroids exists for one very simple reason and that is common dosing protocol. Most all cycles that include Anadrol will start at 50mg per day with 100mg per day being very common place, while conversely most Dianabol cycles will start at 20-30mg per day and while they often go up to 50mg in more hardcore circles, for the average gym rat it is rare. You rarely hear of anyone supplementing with 100mg of Dbol per day outside of elite level bodybuilding but if an individual were to take both steroids, one during the first cycle and the other in a second cycle and at equal doses in both, assuming both forms were of pure quality and all other variables remained the same the gains made from Dianabol would shadow Anadrol into the ground. In the end, while Dbol is more powerful you must find what works best for you, find which you tolerate to a higher degree, regardless of power your personal toleration is of the utmost importance.
