Proviron 25 mg

Proviron 25 mg contains mesterolone, an oral androgen. In medical practice it is used for androgen deficiency in male hypogonadism and has been used to support male fertility. In non-medical bodybuilding contexts, it is commonly referenced as an adjunct during cycles to increase free testosterone, enhance muscle hardness, and provide mild anti-estrogenic effects, though such use falls outside approved indications.

Mesterolone has a terminal half-life of 12–13 hours. In non-medical contexts, it is typically referenced as being taken once or twice daily to maintain stable blood levels. Medical dosing is individualized based on the condition being treated.

Mesterolone is not typically used as a standalone cycle compound, so traditional PCT is not structured around it. However, it does suppress endogenous testosterone production at higher doses. Standard PCT protocols should be considered after the broader cycle concludes, with agents such as Clomid or Nolvadex commonly referenced.

Mesterolone is an orally active androgen that binds to androgen receptors and does not aromatize to estrogen. Its primary role in non-medical contexts is as an adjunct that binds SHBG to increase free testosterone concentrations. It has strong androgenic activity but weak anabolic effects due to inactivation in skeletal muscle tissue.

Mesterolone is rapidly absorbed, with peak serum levels occurring at approximately 1.6 hours after oral ingestion. Its effects on free testosterone and muscle hardness are typically observed over the course of a cycle rather than acutely. Medical effects on androgen deficiency may take several months to manifest.

There is no universally "best" oral androgen. Mesterolone is distinguished by its non-alkylated structure, lack of aromatization, and SHBG binding. Other oral compounds such as Anavar 50 or Halotestin have different trade-offs. The appropriate choice depends on individual goals and risk tolerance.

Mesterolone is a non-17-alpha-alkylated androgen with weak anabolic effects, while oxandrolone (Anavar) is a 17-alpha-alkylated oral anabolic steroid with more pronounced anabolic activity. Both are non-aromatizing. Dragon Pharma offers Anavar 50 as an oxandrolone-based product.

Mesterolone is the active substance, and Proviron is a brand name for mesterolone tablets. Proviron 25 mg by Dragon Pharma contains mesterolone as its active ingredient. The terms are used interchangeably in non-medical discussions.

Medical mesterolone dosing ranges from 50–100 mg daily for androgen deficiency. In non-medical contexts, 25 mg per day is a common starting point, with reference ranges extending to 75–100 mg per day. Proviron 25 mg is labeled at 25 mg per tablet, allowing for flexible dosing.

Proviron 25 mg is labeled at 25 mg of mesterolone per tablet. It is supplied in a 100-tablet package, giving 2,500 mg of total labeled mesterolone content.

Yes. Published laboratory reports for Proviron 25 mg are available. The most recent report dated July 20, 2026 measured the product at 29.91 mg per tablet, equivalent to 119.64% of its 25 mg label claim. Complete reports can be viewed in the Lab Reports tab.

Mesterolone is not 17-alpha-alkylated, which gives it little or no potential for hepatotoxicity compared to most oral anabolic steroids. However, rare cases of benign and malignant liver tumors have been observed after the use of hormonal substances such as mesterolone. Liver function should be monitored during medical use.
