Primobolan belongs to the anabolic steroids that are popular among bodybuilders. This is due to its qualities such as safety and good tolerance by the body. The main goal of using a Primobolan course is to gain muscle mass and maintain body definition.
Primobolan – description of the active substance
The active substance of the medication is methenolone – a derivative of dihydrotestosterone, which is characterized by a low androgenic index (44%) and a moderate anabolic index (88%). In the body, Primobolan stimulates the growth of protein structures, resulting in a rapid increase in muscles that are characterized by hardness and elasticity.
The medication does not undergo aromatization, which eliminates the occurrence of such side reactions. Negative androgenic symptoms are also not typical for it.
Primobolan is available in two forms – injectable and oral. The injectable form has a longer duration of action. It also has a less negative impact on the body. However, injections are associated with pain.
The duration of activity of the injectable form is approximately 2 weeks. The tablet form retains activity for a much shorter time – up to 5 hours.
Course of administration and dosage of the injectable medication
Despite Primobolan being considered a mild steroid, it is advisable to consult a doctor before starting a course. It is also important to determine the optimal individual dosage of the medication.
The Primobolan solo course lasts for 8 weeks:
| Week | Primobolan | PCT – Tamoxifen |
| 1 | 400 mg/week | |
| 2 | 400 mg/week | |
| 3 | 400 mg/week | |
| 4 | 400 mg/week | |
| 5 | 400 mg/week | |
| 6 | 400 mg/week | |
| 7 | 400 mg/week | |
| 8 | 400 mg/week | |
| 9 | ||
| 10 | ||
| 11 | 20 mg/day | |
| 12 | 20 mg/day | |
| 13 | 10 mg/day |
Dosage of 400 mg per week in a single injection is considered safe for health and allows for the gain of lean muscle mass and achieving a sculpted physique.
Recommendations for PCT (Post Cycle Therapy)
Three weeks after completing the course, post cycle therapy should be initiated to normalize natural testosterone production. Tamoxifen or Clomiphene are suitable for this purpose. Additionally, cortisol blockers and testosterone boosters are used for body recovery.
Some athletes may extend the course to 10 or 12 weeks. In such cases, the use of Gonadotropin is necessary starting from the 4th or 5th week of the course: 250 IU twice a week.
Effects of a Primobolan solo course
Primobolan demonstrates its effectiveness in both bulking and cutting cycles. Its benefits are also noticeable during the period between competitions.
The substance contributes to the following outcomes:
- Increased physical strength of the athlete;
- Accelerated protein synthesis;
- Improved endurance;
- Enhanced muscle definition;
- Elimination of excess fluid from the body;
- Fat tissue breakdown.
Due to its limited anabolic and androgenic effects, athletes are protected from many negative symptoms associated with steroid substances.
Contraindications for the use of a Primobolan course
Only proper administration, adherence to dosage, course duration, and following the doctor’s recommendations can ensure good results. It is also important to determine if there are any contraindications for use:
- Hypersensitivity to the composition and active substance;
- Liver insufficiency;
- Kidney diseases;
- Cardiovascular diseases;
- Pregnancy;
- Lactation period.
The presence of any such symptoms is a reason to postpone the course until they are resolved.
