Primabol is a steroid compound that is described chemically as 17(3-Hydroxy-1 -methyl- 5 a-androst-1 -en-3 -one heptanoate. Primabol is a sterile solution of Methenolone Enanthate. By considering its anabolic to androgenic ratio, users will be able to conclude that the steroid is quite mild but is still efficient in different uses – as compared to Masteron because Primobolan has higher androgenic (testosterone replacements) and anabolic (muscle growth) effects. The drug can be taken in both injectable and oral form.
