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 to Testosterone 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, or testosterone 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.

Since Primobolan does not convert to estrogen, it displays many favorable characteristics. Estrogen related side effects should therefore not be seen at all when using this steroid. Sensitive individuals need not worry about developing gynecomastia, nor should they be noticing any water retention with this drug. The gains 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. At higher dosages strong testosterone suppression will be noticed, as all steroids can act to suppress testosterone production at a given dosage. Here of course a proper post cycle therapy is a must.

Side effects in general are usually not much of a problem with Primobolan Depot. There is a chance one will notice a few residual androgenic effects such as oily skin, acne, increased facial/body hair growth or an aggravation of male pattern baldness condition. This steroid is still very mild however, and such problems are typically dose related. Women will in fact find this preparation mild enough to use in most cases, observing it to be a very comfortable and effective anabolic. If both the oral and injectable were available for purchase, the faster acting oral should probably be given preference however. This is simply due to the fact that blood hormone levels are more difficult to control with a slow acting injectable, the user also having to wait many days for steroid levels to diminish if side effects become noticeable. Overall, Primobolan Depot is actually considered to be one of the safest anabolic steroids available. Steroid novices, older athletes or those sensitive to side effects would undoubtedly find it a very favorable drug to use. The typical "safe" dosage for men is 100-200mg per week, a level that should produce at least some noticeable muscle growth. In European medicine it is not uncommon for Primobolan to be used safely at such a dosage for extended periods of time. Among athletes, men may respond to weekly doses of 200mg but regular users will often inject much higher doses looking for a stronger anabolic effect. It is not uncommon for a bodybuilder to take as much as 600 or 800mg per week, a range which appears to be actually quite productive. Of course androgenic side effects may become more pronounced with such an amount, but in most instances it should still be quite tolerable.

In addition, it is most popular for male bodybuilders to stack Primobolan with other steroids in order to obtain a faster and more enhanced effect. During a dieting or cutting phase, a non-aromatizing androgen like Halotestin or trenbolone can be added. The strong androgenic component should help to bring about an added density and hardness to the muscles. On the other hand (or in addition) we could add Winstrol, another mild anabolic steroid. The result of this combination should again be a notable increase of muscle mass and hardness, but in this case the gain should not be accompanied by greatly increased side effects. As mentioned earlier, Primobolan Depot is also used effectively during bulking phases of training. The addition of testosterone, Dianabol or Anadrol would prove quite effective for adding new muscle mass. Of course we would have to deal with estrogenic side effects, but in such cases Primobolan should allow the user to take a much lower dosage of the more "toxic" drug and still receive acceptable results.

Women respond well to a dosage of 50-100mg per week, although (as stated above) the oral should usually be given preference. Additionally, some choose to include Winstrol Depot or Oxandrolone and receive a greatly enhanced anabolic effect. Remember though, androgenic activity can be a concern and should be watched, particularly when more than one anabolic is used at a time. If stacking, it would be best to use a much lower starting dosage for each drug than if they were to be used alone. This is especially good advice if you are unfamiliar with the effect such a combination may have on you. A popular recommendation would also be to first experiment by stacking with oral Primobolan, and later venture into the injectable if this is still necessary.
