Provilbol (Mesterolone) from Evolve Biolabs promotes testosterone production and improves sperm count and quality. It is especially recommended for the treatment of male infertility and hypogonadism. The drug is used to improve muscle tone and definition during physical development, as well as to reduce the side effects of other estrogen-containing steroids.
Provilbol, also sold as Mesterolone 25mg tablets, is a combination of androgens and anabolic steroids. The dose of dihydrotestosterone (DHT), a mesterolone derivative found in pharmaceutical formulations, is 25mg.
The mechanism of action of mesterolone is to suppress the aromatization process by an antiestrogen. As a result, the concentration of female hormones in the body decreases. It is quite obvious that this drug should be used in courses of aromatizing anabolic steroids.
Let's note the most important positive properties for athletes:
Improves the quality and increases the quantity of spermatozoa. Compensates for the insufficiency of production of male sex hormones (androgens), stimulating the development of male genitals and secondary sexual characteristics, improves libido and potency, exhibits anabolic properties, stimulates erythropoiesis.
Directions for use: orally, without chewing, 25 mg 1-3 times a day.
For men, the normal dose of the drug is 75-150 mg, and for women - 25 mg. However, athletes usually overestimate the dosage, increasing it to 250 mg and 50 mg, respectively. This is the maximum permissible value, at which side effects can still be avoided. Exceeding the specified value can lead to the fact that the drug, instead of reducing the harmful effects of anabolic steroids and maintaining libido and normal erection, can lead to a long-term painful erection. This is a signal to reduce the daily dose of the drug.
Considering that the drug increases libido and improves potency in men, its use is justified during a course of drugs that reduce libido (for example, deca-dic when using nandrolone or tren-dic from trenbolone).
In addition, Proviron is often used in bodybuilding in pre-competition preparation to increase muscle hardness and give it relief. It is a favorite drug of Western movie actors to give their appearance muscularity, who are afraid to use heavier steroid "artillery". It is also used by female bodybuilders to give muscle density, but their dosages should not exceed 25 mg per day for no more than four weeks to exclude the phenomenon of masculinization. Although professional bodybuilders do not adhere to these standards.
It is not toxic to the liver in moderate doses, which makes it safe to take during a course of several weeks. It does not suppress the hypothalamic-pituitary-testicular axis. Given the chemical nature and similarity to dihydrotestosterone, such side effects as prostate hypertrophy and male-pattern baldness of the scalp are possible.
For prevention purposes, periodic examination of the prostate gland is recommended. Caution for use. After taking the hormonal substances included in the drug Proviron, the formation of benign, and even more rarely - malignant liver tumors has been observed very rarely. In some cases, intra-abdominal bleeding caused by such tumors was life-threatening. If a man who uses Proviron experiences severe pain in the upper abdomen, an enlarged liver, or there are signs of intra-abdominal bleeding, the possibility of a liver tumor must be taken into account when conducting differential diagnostics.
