Proviron – 25mg (50 tabs)

Proviron 25 mg is an oral medication containing 25 mg of mesterolone per tablet. Mesterolone is a synthetic androgen derived from dihydrotestosterone (DHT). It has been used in certain clinical settings under medical supervision.

Active Ingredient

Mesterolone is an orally active androgen that does not convert to estrogen through aromatization. As a DHT derivative, it primarily exhibits androgenic activity with relatively limited anabolic effects.

Composition

Each tablet typically contains:

• Mesterolone – 25 mg

• Pharmaceutical excipients such as fillers, binders, and stabilizing agents

Inactive ingredients vary depending on the manufacturer.

Mechanism of Action

Mesterolone binds to androgen receptors in target tissues. It may influence male secondary sexual characteristics and can affect hormone-binding proteins such as sex hormone–binding globulin (SHBG). Because it does not aromatize, it does not increase estrogen levels.

Medical Uses

Mesterolone has been prescribed in certain cases of male hypogonadism and infertility associated with androgen deficiency. Treatment is determined and monitored by a qualified healthcare professional.

Pharmacological Characteristics

Mesterolone is active after oral administration and undergoes hepatic metabolism. Unlike some other oral androgenic agents, it is not typically associated with significant liver toxicity at therapeutic doses, though monitoring is still recommended.
