Primobolan Depot is the injectable version of the steroid methenolone . Primobolan Depot of course is the same constituent in Primobolan Oral's (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 of Primobolan is also quite mild, its potency considered to be slightly less than Deca Durabolin on a milligram for milligram basis. For this reason, methenolone 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 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 depot is indispensable to the competitor
Primobolan will also not aromatize, so estrogen related side effects are of no concern. This is very useful when leading up to a bodybuilding contest, as subcutaneous water retention (due to estrogen) can seriously lessen the look of hardness and definition to the muscles. Non-aromatizing steroids are therefore indispensable to the competitor, helping to bring about a tight, solid build the weeks leading up to a show. And of course without excess estrogen there is little chance of the athlete developing gynecomastia. Likewise there should never be a need for antiestrogen use with this steroid. Primobolan depot is also said to have a low impact on endogenous testosterone production. Although this may well be true in small clinical doses, it will not hold true for the bodybuilder. For example, in one stud more than half of the patients receiving only 30-45 mg noted a suppression of gonadotropin levels of 15% to 65% a. This is a dose far less than most bodybuilders would use, and no doubt increasing it would only lead to worse suppression. One would therefore still need a testosterone stimulating drug like HCG (Human Chorionic Gonadotropin) or Clomid/Nolvadex when concluding a low-dose Primobolan cycle, unless a deliberately small dose were being used.
