Proviron 25 – Product Overview
Proviron (Mesterolone) is one of the earliest DHT-derived androgens developed for clinical and performance-related research. Supplied in a bottle of 50 tablets at a strength of 25mg each, Proviron is recognized for its strong androgenic activity, SHBG-binding properties, and its unique ability to enhance muscle hardness and overall physique appearance.
Scientific Background
Mesterolone is structurally modified DHT with a methyl group added at carbon-1, allowing it to remain orally active without the hepatotoxicity commonly associated with C17-alpha-alkylated steroids. Although its anabolic rating appears high on paper, its real-world anabolic effect is mild, while its androgenic characteristics are more pronounced.
Key Research-Based Characteristics
- High SHBG Affinity: Proviron demonstrates strong binding to Sex Hormone Binding Globulin, increasing the proportion of unbound androgens in circulation.
- Non-Estrogenic Profile: As a DHT derivative, Mesterolone does not aromatize, and has been studied for interactions with the aromatase enzyme.
- Physique Hardening Effects: Frequently referenced in research related to improving muscle density, dryness, and definition during cutting conditions.
- Androgen Receptor Activation: Exhibits notable androgenic activity that may enhance the effects of other anabolic agents in stacked research environments.
- Impact on Fertility Research: Historically studied for its role in male fertility, sperm quality, and androgen-deficiency models.
