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 toxic to the liver, especially the oral versions, although the toxicity is gradual and slight.

Acne and hair loss can occur with long-term use. 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.
