Dianabol (methandrostenolone, methandienone) has been one of the most important anabolic steroids in bodybuilding ever since its introduction in 1958. Also commonly known as “Dbol”, this oral compound is best used for steroid cycles in combination with injectable steroids, but can be of value used alone as well.
The effect of most injectable anabolic steroids is greatly enhanced by addition of Dianabol. The improvement is greater than from simply increasing the amount of injectable by the same amount. A classic and dramatic example is trenbolone. Though the total amount of steroid used is the same in all three cases, 50 mg/day each of trenbolone acetate stacked with 50 mg/day Dianabol provides a far more effective steroid cycle than either 100 mg/day of trenbolone acetate alone or 100 mg/day Dbol alone. The side effect profile is superior as well. In other words, the compounds act synergistically: the whole is greater than the parts. This is likely due to different mechanisms of action.
