Primobolan (methenolon)

Primobolan and its varieties

Primobolan - Methenolone (more commonly known as Primobolan, also Primobol, Nibal) is an anabolic steroid, a dihydrotestosterone derivative with weak androgenic activity and moderate anabolic action. It is available in pills (Primobolan) and in injectable form (Primobolan Depot). Many athletes compare Primobolan and Masterone in effectiveness.

Primobolan Depot is an injectable form of the drug, which is an ester of methenolone enanthate. The injectable form has a long period of action (due to the gradual transfer of the drug from the muscles into the bloodstream), approximately two weeks. In terms of duration of action Primobolan Depot is similar to Testosterone enanthate. The main disadvantage of this form is that it is painful to inject. Injection acetate is less common, with a short half-life, up to about two days.

Primobolan Oral, a form of metenolone in tablets (metenolone acetate), has a much shorter half-life (about 5 hours). Primobolan in tablets has a higher price. The distinctive feature of the tablet form is the absence of toxic effects on the liver, unlike most other oral forms of steroids.

The effects of Primobolan

The anabolic effect of Primobolan is quite mild and comparable to Deca, so this drug is more often used during drying cycles, when the main goal is not to gain muscle mass, but to preserve it. Metenolone has a minimal rollback phenomenon, however, many athletes are not satisfied with the results obtained after a course of Primobolan solo if the purpose was to gain muscle mass.

Primobolan - Side Effects

Primobolan (both forms) do not convert to estrogens, which is one of the main advantages of the drug. As a result, you can take primobolan without the risk of developing gynecomastia and edema. Although gynecomastia may be indicated in some instructions.

Primobolan slightly reduces your own testosterone production. Its suppressive effects are weaker than testosterone and nandrolone. Studies show that a course of Primobolan at a dose of 40 mg (orally) suppresses testosterone levels by an average of 50%.  A significant decrease in endogenous testosterone production is observed only during long courses with large doses of the drug. In these cases, the use of gonadotropin is required during the course, otherwise testicular atrophy may develop.

Metenolone practically does not cause the rise of harmful cholesterol. The drug has no significant effect on blood pressure levels.

Due to its low androgenic action, primobolone causes almost no baldness. The most common side effects of metenolone are aggression, agitation, insomnia, and elevated liver enzymes if high doses are used.

Thus, primobolan can be considered one of the safest anabolic steroids currently available on the market.

Primobolan course

• Primobolan course is best suited during the drying cycle to preserve muscles and gain relief.
• The mild action of the drug requires a longer course (up to 8 weeks), but as the duration of the primobolan course increases, the risk of side effects increases.
• The dosage of primobolan oral is 50-100 mg per day. Two to three days after the end of the dose, post-course therapy begins.
• The dosage of primobolan depot is 400 mg, once a week. After 3 weeks after the last injection, post-course therapy begins.
• Before starting the course, a doctor's consultation is required to exclude contraindications.
