Proviron by Zyvex Pharmaceuticals
What Is Proviron?
Proviron from Zyvex Pharmaceuticals is mesterolone in a 25 mg tablet, 100 tablets per pack. Mesterolone is an oral DHT derivative with a narrow but useful role: it binds strongly to SHBG, freeing up more active testosterone, and it carries an anti-estrogenic character without suppressing natural production much.
In cycle practice Proviron sits on the support shelf rather than the anabolic shelf. Users add it for libido support, a harder look and more free test in the blood, often through a cycle and into PCT. Because it is mostly inert as a mass builder, it is judged by what it supports, not what it adds.
Proviron Dosage
Daily oral dosing, with the 25 mg tablet as the standard unit.
| Situation | Daily Dose | Schedule |
|---|---|---|
| Libido and free test support | 25 mg | Once daily |
| Standard cycle support | 50 mg | Split in 2 Common |
| Full support run | 75 mg | 3 doses through the day |
Proviron is usually run for the length of a cycle or PCT. A bottle of 100 at 50 mg a day lasts 50 days.

- Liver - light load compared with alkylated orals.
