Proviron 25 mg Mesterolone (20 Tablets)

Proviron 25 mg is a prescription oral medication containing the active ingredient Mesterolone. Manufactured by Bayer, it is a unique androgen used in the medical treatment of male hypogonadism (low testosterone levels) and to support hormonal balance in men. This package contains 20 tablets.

Product Overview: Proviron 25 mg (Mesterolone)

Proviron 25 mg (Mesterolone) is an oral androgen that is structurally similar to dihydrotestosterone (DHT). Unlike injectable testosterone or some other oral androgens, Proviron has a unique profile.

It is medically prescribed to treat the symptoms of androgen deficiency (low testosterone) in men, which can include reduced libido (sex drive), low energy levels, erectile dysfunction, and depressed mood.

A key feature of Proviron is that it does not aromatize (convert to estrogen). It also has a strong binding affinity for Sex Hormone-Binding Globulin (SHBG), which can increase the amount of “free” (usable) testosterone circulating in the body.

How Does Proviron 25 mg (Mesterolone) Work?

The active ingredient, Mesterolone, works in two primary ways:

1. As an Androgen: It provides a direct source of androgenic activity, helping to supplement the body’s own low testosterone levels and alleviate symptoms of deficiency.
2. Binds to SHBG: Mesterolone binds very strongly to SHBG, a protein that “locks up” testosterone, making it inactive. By binding to SHBG, Proviron “bumps” testosterone off the protein, freeing it up and increasing the body’s levels of free, bioavailable testosterone.

Because it is a pure androgen and does not convert to estrogen, it does not cause estrogenic side effects like water retention or gynecomastia.

Frequently Asked Questions (FAQ) about Proviron 25 mg

Is Proviron 25 mg a steroid?

Yes, Mesterolone (Proviron) is an anabolic-androgenic steroid (AAS). However, its anabolic (muscle-building) properties are considered very weak. Its primary action is as a pure androgen.

Is Proviron 25 mg the same as Testosterone?

No. While both are androgens, they work very differently. Testosterone (like injectables) is the body’s primary hormone and can convert to estrogen. Proviron (Mesterolone) is a DHT-derivative that does not convert to estrogen and works by increasing “free” testosterone.

Why is Proviron used in bodybuilding (off-label)?

Proviron is used “off-label” in bodybuilding cycles for two main reasons:

1. To act as a mild anti-estrogen by binding to the aromatase enzyme (though less effective than modern AIs).
2. To bind to SHBG, which “liberates” other steroids in the cycle, making them more effective. This is a non-medical use and carries significant health risks.

What are the common side effects of Proviron?

Because it is a DHT-derivative, side effects are primarily androgenic. These can include oily skin, acne, and male pattern hair loss (baldness) in genetically predisposed individuals. It can also negatively impact cholesterol levels.

Important Safety Information

Warning: Proviron (Mesterolone) is an androgenic steroid and is not suitable for everyone.

Do not use Proviron 25 mg if you:

• Have or are suspected to have prostate cancer.
• Have or have had liver tumors.
• Have male breast cancer.

This medication is for male use only and must not be used by women, as it carries a very high risk of virilization (development of irreversible male characteristics). Misuse of this drug for performance enhancement can lead to serious cardiovascular and psychological side effects.
