Provibol

Provibol (active ingredient: mesterolone) is an oral androgenic steroid derived from dihydrotestosterone (DHT). It is a generic or alternative brand-name formulation corresponding to the well-known medication Proviron.

Unlike many typical anabolic steroids, Provibol has very weak muscle-building (anabolic) properties, meaning it is rarely used for mass building; instead, it is utilized primarily for its unique hormonal and binding interactions.

Description

Provibol is an oral tablet designed to supplement male androgens and alter how other hormones behave in the body without aromatizing into estrogen.

• Active Compound: Mesterolone

• Form: Oral tablets (typically 25 mg)

• Class: Oral Androgenic-Anabolic Steroid (DHT derivative)

• Mechanism: Binds strongly to Sex Hormone-Binding Globulin (SHBG) and androgen receptors. By occupying SHBG, it frees up other circulating testosterone to become active in the body. It also acts as an anti-aromatase to a minor degree.

Medical Benefits & Uses

Clinically, Provibol is prescribed to treat specific male endocrine and reproductive challenges:

1. Hypogonadism & Androgen Deficiency: Replaces missing male hormones in men whose bodies do not produce adequate natural testosterone.

2. Male Infertility: Used to address certain cases of low sperm count (oligozoospermia) or impaired sperm motility to support fertility.

3. Psychosexual Support: Prescribed historically to combat low libido, fatigue, and depressive states tied directly to low androgen levels.
