Primobolan ® Depot is the injectable version of the steroid methenolone. This of course is the same constituent in Primobolan© Orals (methenolone acetate), both produced by the firm Schering. In this preparation, an enanthate ester is added to the steroid, which causes a slow and gradual release from the site of injection. Its duration of activity would thus be quite similar to Testosterone enanthate, with blood levels remaining markedly elevated for approximately two weeks. Methenolone itself is a long acting anabolic, with extremely low androgenic properties. On the same note the anabolic effect is also quite mild, its potency considered to be slightly less than DecaDurabolin® (nandrolone decanoate) on a milligram for milligram basis. For this reason, Primobolan is most commonly used during cutting cycles when a mass increase is not the main objective. Some athletes do prefer to combine a mild anabolic like “Primo” with bulking drugs such as Dianabol, Anadrol 50® or testosterone however, presumably to lower the overall androgen dosage and minimize uncomfortable side effects. When choosing between Primobolan preparations, the injectable is preferred over the oral for ail applications, as it is much more cost effective.
Primobolan displays many favorable characteristics, most which stem from the fact that methenolone does not convert to estrogen. Estrogen linked side effects should therefore not be seen at all when administering this steroid. Sensitive individuals need not worry about developing gynecomastia, nor should they be noticing any water retention with this drug. The increase seen with Primobolan will be only quality muscle mass, and not the smooth bloat which accompanies most steroids open to aromatization. During a cycle the user should additionally not have much trouble with blood pressure values, as this effect is also related (generally) to estrogen and water retention. At a moderate dosage of 100-200mg weekly, Primobolan® should also not interfere with endogenous testosterone levels as much as when taking an injectable nandrolone or testosterone. This is very welcome, as the athlete should not have to be as concerned with ancillary drugs when the steroid is discontinued (a less extreme hormonal crash). At higher doses strong testosterone suppression may be noticed however, as all steroids can act to suppress testoste
