USAGE

his section refers to the oral Primobolan ® preparation, which contains the drug methenolone acetate. It is very similar in action to the injectable Primobolan ® Depot (methenolone enanthate), but obviously here the drug is designed for oral administration. At one time Schering was in fact also manufacturing an injectable methenolone acetate (Primobolan ® acetate, out of manufacture since 1993), which proved to be very useful for pre-contest cutting purposes. This steroid is now gravely missed, as it was once a favorite among European competitors. Although we still have the acetate in oral form, it is a close, but not equal substitute (injection is a much more efficient form of delivery for this steroid).

Methenolone regardless of the ester is a very mild anabolic steroid. The androgenic activity of this compound is considerably low, as are its anabolic properties. One should not expect to achieve great gains in muscle mass with this drug. Instead, Primobolan ® is utilized when the athlete has a specific need for a mild anabolic agent, most notably in cutting phases of training. It is also a drug of choice when side effects are a concern. A welcome factor is that Primobolan ® is not c17 alpha alkylated as most oral steroid are. Due to the absence of such an alteration, this compound is one of the few commercially produced oral steroids that is not notably stressful to the liver. While liver enzymes values have been affected by this drug in some rare instances, actual damage due to use of this substance is not a documented problem. Unfortunately the 1 alkylation and 17-beta esterification of Primobolan ® do not protect the compound very well during first pass however, so much of your initial dose will not make circulation. This is obviously why we need such high daily dose with the oral version of Primobolan ®.

Applications

Primobolan (methenolone acetate), all things being equal, is an excellent oral steroid drug. Unlike most other oral steroids, Primobolan is not 17-alkylated and does not have liver toxicity problems.

Primobolan is a good base compound in a stack and can produce results just slightly below that of nandrolone and is best used in a cutting stack. Because Primobolan doesn’t aromatize, there is no use for Clomid or Nolvadex.

Primobolan Depot is the injectable version of the steroid methenolone. It is the same compound as the one in Primobolan Orals (methenolone acetate), both produced by Schering. In this injectable version, an enanthate ester is added to the steroid, which makes for a slow and gradual release from the site of injection. Its length of activity would thus be quite similar enanthate, with blood levels remaining elevated for approximately two weeks.

Methenolone itself is a long acting anabolic, with extremely low androgenic properties. It's anabolic effect is also quite mild, its potency is 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 goal. Some athletes do prefer to combine a mild anabolic like "Primo" with bulking drugs such as Dianabol, Anadrol, however, presumably to lower the overall androgen dosage and minimize uncomfortable side effects. When choosing between Primobolan versions, the injectable is preferred over the oral, as it is much more cost effective.
