Proviron Mesterolone 20mg 50 Tablets
Proviron (Mesterolone) is an oral androgenic compound available as 20mg tablets, 50 tablets per container. Unlike traditional anabolic steroids, it is not a mass-building agent. Its primary value comes from two specific pharmacological actions: strong SHBG binding and partial aromatase inhibition.

Key Features
Dosing and Usage
The standard daily dose is 20-60mg (1-3 tablets), split between morning and evening for stable blood levels. Because liver toxicity is not a concern, Proviron can be run for the full duration of a cycle.
It is best suited for cutting phases, pre-contest preparation, and cycles involving Nandrolone or Trenbolone. Recommended stack partners include Testosterone (any ester), Winstrol, and Anavar. Proviron is mildly suppressive to natural testosterone production and is not recommended for use during post-cycle therapy.
Key Features and Benefits
- Stack amplification – frees bound testosterone and other compounds, improving bioavailability across your entire protocol
- Harder, drier physique – reduced water retention, better muscle separation, and increased vascularity
- Libido and sexual function support – particularly useful when running Nandrolone or Trenbolone, which commonly suppress sexual function
- Extended use capability – 1-methylated structure bypasses the hepatotoxic C17-alpha alkylation pathway, allowing full-cycle use without liver strain
- No aromatization – does not convert to estrogen
How It Works
Mesterolone binds to SHBG with an affinity exceeding that of testosterone itself. By occupying SHBG receptor sites, it prevents this protein from binding to circulating testosterone and other stacked compounds, increasing the proportion of free, biologically active hormone.
Proviron also provides moderate aromatase inhibition, reducing estrogen conversion from aromatizing steroids. This produces a drier, harder appearance with improved muscle definition and vascularity. Intended for adult male use only. Store in a cool, dry place away from direct sunlight and out of reach of children.
