Provironus 25 mg (Mesterolone) 50 Tabs
Active ingredient: Mesterolone
Type: Anabolic steroids (DHT derivatives)
Form: Oral (tablets)
What is Mesterolone?
Mesterolone, sold under the brand name Proviron, is an orally active androgen and anabolic steroid (AAS) medication that is primarily used to treat low androgen levels and their consequences – low libido. It has also been used to treat male infertility, but this use is somewhat controversial.
Mesterolone is mainly sold in 25 mg tablets as Proviron 25 mg, but if you buy mesterolone (Proviron 25 mg) online, it may be sold in different strengths.
Mesterolone is unique among AAS because it is not an esterified form of testosterone, meaning it is not converted into estrogen in the body. This makes it particularly useful for certain therapeutic applications without the side effects associated with estrogen.
It should be used in men with androgen deficiency: It is most appropriate for men who have been clinically diagnosed with hypogonadism and for whom the benefits of treatment outweigh the risks.
Common use cases also include a deficiency of the 5-alpha reductase enzyme, which reduces the conversion of testosterone to dihydrotestosterone (DHT), a more androgenic form that is an important neuroandrogen. Proviron seamlessly penetrates the blood-brain barrier and stabilizes the androgen receptor in the brain, allowing it to be used as an antidepressant with a significant positive impact on libido.
Benefits of Mesterolone for the Body
Mesterolone (Proviron) has several potential benefits, particularly in the context of treating androgen deficiencies and related conditions. Here are some of the main benefits associated with Proviron:
Androgen replacement
: Proviron can effectively supplement androgen levels in men suffering from androgen deficiency or hypogonadism, helping to alleviate symptoms such as reduced libido, depression, fatigue, and muscle loss.
Improved libido and sexual function.
One of the most notable benefits of Mesterolone is its ability to improve libido and sexual function, which may be diminished. Unlike some other forms of testosterone replacement therapy, Proviron has a direct effect on libido due to its androgenic properties.
Psychological and physical well-being:
The increase in androgen levels due to Proviron (Mesterolone) can contribute to a general feeling of well-being, improved mood, and increased energy levels. The androgenic effects also support the maintenance or increase of muscle mass and strength, contributing to better physical condition.
Fertility support:
Proviron has been used to improve sperm quantity and quality in some men with fertility problems, although its effectiveness may vary. It is believed to increase fertility by increasing levels of luteinizing hormone (LH) and follicle-stimulating hormone (FSH), which stimulate sperm production.
Use in sports:
Bodybuilders and athletes have used Mesterolone (Proviron) for its ability to provide a muscle-hardening effect, increase the potency of other steroids used in cycles through its anti-estrogenic properties, and reduce SHBG (sex hormone-binding globulin) and help maintain libido off-cycle.
Side Effects
: Hair loss: Individuals predisposed to male pattern baldness may experience accelerated hair loss.
Mood swings: Certain users may experience mood swings, such as feelings of irritability or increased aggression.
Liver toxicity: Although less common than with other oral anabolic steroids, prolonged use still poses a risk of liver damage.
Prostate enlargement: Long-term use may contribute to an increase in prostate size, posing risks for individuals with prostate cancer.
Cardiovascular problems: There may be an increased risk of cardiovascular problems, including changes in cholesterol levels leading to hardening of the arteries.
Virilization in Women: This risk is significant if used by women, which is generally not recommended. Mesterolone (Proviron) can cause virilization, deepening of the voice, increased body hair, and changes in the menstrual cycle.
Proviron can be used in various ways and regimens. The
usual daily dose starts at 25 mg and can be increased up to 100 mg.
To reduce SHBG during a steroid cycle or increase androgen levels, a dosage of 50 mg/day is sufficient in most cases.
The dose to increase libido usually starts at 50 mg/day.
Doses higher than 25 mg should be divided into two doses.
Contraindications/Precautions:
Men diagnosed with or suspected of having prostate or breast cancer should not use Mesterolone (Proviron), as androgens may accelerate the growth of prostate cancer cells.
Additionally, Mesterolone may cause increased blood pressure, so you should consult a doctor before using it.
Other contraindications/precautions include: Hypercalcemia, Pregnancy and Breastfeeding, Hypercalcemia, Liver Disease, Heart Disease, and Heart Failure.
Storage:
Store Mesterolone (Proviron) at room temperature, typically between 20°C and 25°C (68°F to 77°F). Avoid exposure to extreme temperatures.
Keep it in a dark place to protect it from light and moisture, which can degrade Mesterolone (Proviron). Avoid freezing and keep it out of reach of children and pets.
