Primobolan-100 is an injectable steroid made by Platinum Biotech Europe, this steroid contains Methenolone Enanthate.
Primobolan-100 is the injectable version of the steroid methenolone and, although it produces a weaker effect than Deca Durabolin it is a very good basic steroid whose effects are predominantly anabolic. The fact that an enanthate ester is added to this steroid enables a slow and gradual release from the injection site. This addition allows for a longer half-life of approx 14 days (similar to Testosterone Enanthate) although most athletes prefer to administer it on a weekly basis.
Primobolan-100 popularity stems from the fact that it is the only steroid that seems to work well on a low calorie diet (making it a pre-contest drug of choice) and side effects are rarely a problem since it is relatively non toxic, low in androgens and it does not convert to estrogen (aromatize) therefore estrogen related side effects are not an issue. In addition to this it seems to have a positive effect on the immune system (thus its popular use in Aids patients) and the fact that it adds primarily lean mass leads to a strengthening of the whole body system.

Primobolan-100 is commonly used by those who wish to keep oestrogen and androgenic related side effects to a minimum. Primobolan-100 is also a popular choice for cutting cycles due its mild anabolic properties which may be best suited for sustaining muscle tissue under strict pre-content dieting. Excessive subcutaneous fluids will also not be a concern due to Primobolan-100 being a non-aromatising steroid. The compound could also be added to bulking cycles to heighten the anabolic nature of the cycle whilst minimising adding to the overall oestrogen and androgenic side effects.
Androgenic related side effects are usually only confined to the sensitive individuals, or those who opt to take the larger dosages of the product. Primobolan-100 is often regarded as a safe steroid in comparison to other products, and it is a very sought after product which reflects in its cost. A dose of 400 mg a week has been shown to provide decent gains, but higher doses are common, with many claiming 600 - 800 mg a week will provide a much better yield in muscle size whilst not causing too much in terms of side effects. As we rise the dose we can expect the androgenic side effects to become more pronounced, so its down to the user to see what dose provides fruitful when weighing up the side effects to net positive gains.
Primobolan-100 is often stacked with other steroids to provide more pleasing results to the user. During a cutting cycle the product could be stacked with a non-aromatising androgen to aid muscle hardness whilst keeping a very defined look with little water retention. Others may find primobolan a nice compound to add to their usual Testosterone course to add to the anabolic nature of the cycle, whilst not adding too much to side effects. This may be useful for those who have found their tolerance dosage with Testosterone but wish to add another compound to their stack to aid gains.
Primobolan-100 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-100 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 - 200 mg weekly, Primobolan-100 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 testosterone production at a given dosage. Here of course an ancillary drug regimen may be indicated.
It is most popular for male bodybuilders to stack Primobolan-100 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 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-100 is also used effectively during bulking phases of training. The addition of testosterone, Dianabol or Anadrol 50 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-100 should allow the user to take a much lower dosage of the more "toxic" drug and still receive acceptable results.

SIDE EFFECTS:
Side effects in general are usually not much of a problem with Primobolan-100. There is a chance to 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. Primobolan-100 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 - 200 mg per week, a level that should produce at least some noticeable muscle growth.
