Methenolone (more commonly known as Primobolan, as well as Primobol, Nibal) is an anabolic steroid, a derivative of dihydrotestosterone with a weak androgenic activity and moderate anabolic effect. It is available in tablets (Primobolan) and in injectable form (Primobolan Depot). Many athletes compare the effectiveness of Primobolan and Masteron.
Primobolan Oral – a form of methenolone in tablets (methenolone acetate), has a much shorter period of action (about 5 hours). Primobolan in tablets has a higher price. A distinctive feature of the tablet form is the absence of toxic action on the liver, in contrast to most other oral forms of steroids.
Estimating in general two forms of methenolone, the majority prefers the injection form, due to the lower cost and more even flow of the active substance into the blood. In addition, some part of Primobolan in tablets is destroyed in the liver.
