How to use Provironos 50 mg Pharmacom Labs

Provironos is a hormonal drug whose active ingredient is mesterolone. It is a hormone with low androgenic activity, which has several special properties that make it particularly useful during anabolic steroids and as part of post-cycle therapy. Provironos 50 mg Pharmacom Labs is used in bodybuilding and other sports fields.

Main effects Provironos 50 mg Pharmacom Labs

The properties of the drug are versatile. The main ones:

  • able to slightly suppress the activity of the enzyme aromatase, which converts male hormone into female hormone;
  • increases the amount of free testosterone in the blood;
  • reduces the activity of globulin, which binds to anabolic hormones and prevents them from fully manifesting themselves;
  • improves erectile function, significantly increases erection.

The remedy is used as a support when taking anabolic steroids prone to aromatisation. It is also associated with drugs that suppress libido. These include nandrolone or trenbolone.

Provironos is also able to improve the condition of muscles. It increases their hardness, and gives relief to the silhouette. This is due to its androgenic activity. You can use it in preparation for competitions to make the figure as expressive as possible.

Possible negative effects

The drug is safe because it does not overload the liver and does not suppress the work of the testicles. It does not cause aromatization, which means that it cannot cause gynecomastia. However, due to its androgenic properties, high doses may cause prostatic hypertrophy (proliferation of prostate tissue) as well as baldness in predisposed individuals.

Another possible side effect is a permanent erection that does not go away for several hours and causes discomfort. This symptom indicates that the selected dose is too high and should be reduced.

Rules of the course

Provironos 50 mg Pharmacom Labs can be taken for several purposes. To achieve the muscle stiffening effect, it is taken for several weeks as part of pre-competition preparation. Dosage: 50-100 mg per day. It is not recommended to take more than this amount as it increases the risk of side effects.

If you need the properties of mesterolone to suppress aromatisation and maintain testosterone production, it is taken together with other anabolic steroids. After the abolition of the steroid, the course of Provironos also ends and the athlete switches to other anti-estrogens with stronger effects.

Before use, consult your doctor to rule out contraindications.
