Primobolan: properties, doses

Primobolan (methenolone enanthate) is an anabolic steroid derived from dihydrotestosterone. However, it lacks the effects of its chemical precursor. In medicine, this drug is used to treat anemia in women and even children. Methenolone works smoothly but steadily, both on beginners using AAS (anabolic androgenic steroids) for the first time and veterans of the steroid front. Primobolan is available in injectable and oral form. But the latter practically does not work and is almost never used in sports.

Primobolan properties

  1. As Primobolan does not provide a water and fat pool, it is often used by bodybuilders for pre-competition preparation. At the same time, it is worth noting its ability to make the muscles very tight and well-defined.
  1. However, in combination with “mass-gathering” medications, Primobolan gives good results for getting quality muscle mass and increasing strength. Arnold Schwarzenegger himself used it in combination with methandrostenolone during the period of mass gain. Which already says a lot.
  1. Methenolone enanthate’s property of not suppressing endogenous testosterone production when using minimal doses is used to “bridge” between courses. This allows you to save what has been achieved during the break between classes and at the same time restore normal endocrine system function. But Primobolan’s main area of ‚Äč‚Äčapplication is drying up the courses and getting off the AAS course.

Side effects

Primobolan has virtually no side effects, does not aromatize and has no progesterone activity. Its androgenic activity is also very low and even testosterone production is hardly suppressed when methenolone is used. If your treatment only consists of primobolan, you will certainly not gain as much muscle mass, but in all likelihood it will not go away after treatment.

Thus, no appreciable side effects should be expected from Primobolan, especially if maximum doses are not used.


Methenolone enanthate working doses are 400-1000mg per week for men and 200-400mg for women. The half-life of Primobolan is 6-7 days. Therefore, it is better to carry out the injections 1-2 times a week.

Combination and reception system

When gaining weight, Primobolan is used in combination with strong drugs. Like testosterone, nandrolone, methandienone, oxymethalone. In these classes, your task is not so much to increase the mass increase, but to make it better. This means you will have less fat and your muscles will be firmer and deeper.

During the period of fat loss and competition training, Primobolan can be used in conjunction with Stanazolol, Trenbolone, Boldenone, Oxandrolone.

You can also add Testosterone Propionate. To avoid water retention, stop it before competition or use aromatization suppressing medications or anti-estrogens.

Primobolan is suitable for women, but it should not exceed a dose of 200-400 mg per week, and the course duration is 4 weeks. Primobolan is best combined with oxandrolone for women.

Courses for women. The use of Primobolan at a dose of 100 mg/week may reduce the risk of side effects and prolong ASA use. The course is suitable both for gaining muscle mass and strength, as well as preparing for competitions. Recommended for women experienced in the use of pharmacology.
