Stacks: Primo is often used in a stack. It is popular for male bodybuilders to stack Primobolan with other steroids in order to obtain a faster and more enhanced effect. Methenolone (Primo) is also one of the rare steroids that works on a reduced calorie diet. This makes Primobolan depot an ideal part of every cutting stack. For dieting (pre contest preparation) Methenolone works best in stack with T3, Clen, Proviron, Deca, and/or Test. 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 or Anavar, 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 increased side effects. And as mentioned earlier, Primobolan Depot is also used effectively during bulking phases of training. The addition of testosterone, Dianabol or Anadrol prove quite effective for adding new muscle mass. Of course when stacked with those three, 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" drugs and still receive acceptable results.
While athletes and some researchers believe that testosterone produces a mass improvement in performance and endurance, others believe that it cannot produce overnight effects. It cannot give a jolt of energy to sportspersons in order to improve their performance, since testosterone acts over time to build muscle and strength in the athlete. But even then, there has to be a considerable amount of effort (in terms of exercise) on the part of the athlete. Simply taking testosterone without any exercise or a suitable diet will only do more harm than good.
