Proviron (Mesterolone) 25mg by Quanta Pharma

Quanta Pharma Proviron Research Areas

• Raises free testosterone: Binds SHBG strongly, leaving more of the testosterone already present active
• Mild anti-oestrogenic effect: Competes at the aromatase enzyme, useful, but not a replacement for a proper AI
• Hardening: Reported on a lean physique; does almost nothing visible on a soft one
• Minimal anabolic contribution: Nobody runs this for tissue, it makes a base work harder

How Proviron Works

Mesterolone binds sex hormone binding globulin, which is what holds testosterone in circulation in an unusable bound state. Occupying SHBG leaves a greater share of that testosterone free and active.

So proviron does not add hormone. It makes more of what is already there available, which is why it is run alongside a base rather than on its own.

Proviron vs an Aromatase Inhibitor

Proviron’s weak anti-oestrogenic activity gets it discussed as a light alternative to an AI. Treat that carefully, on a cycle that genuinely needs oestrogen control, an aromatase inhibitor is the correct tool and proviron is not a substitute.

Where proviron earns its place is the SHBG effect, which an AI does not provide at all.
