Not a rapid mass builder, boldenone undecylenate instead provides a slow but steady gain of strength and quality muscle mass. The positive effects of this drug become most apparent when it is used for longer cycles, usually lasting eight weeks or more in duration. The muscle gained should also not be the smooth bulk associated with testosterone, but more defined and solid. Since water bloat is not contributing greatly to the diameter of the muscle, more of the visible size gained on a cycle of boldenone undecylenate should be retained after the drug has been discontinued. It is most commonly used at a dosage of 200-400 milligrams per week (men).
