Product overview

Zyvex Pharmaceuticals Proviron 25 mg Mesterolone Tablets

Zyvex Pharmaceuticals Proviron is mesterolone at 25 mg per tablet, one of the very few orally active androgens that is not 17-alpha-alkylated. The checked file describes it as strongly androgenic and weakly anabolic, with a low hepatic rating, no aromatisation and therefore no water retention. Buy proviron here when the goal is support rather than a standalone cycle, because that is where community practice puts it.

How Mesterolone Works

Mesterolone binds sex hormone binding globulin, the protein that carries a large share of circulating testosterone, and community use revolves around that property: the theory is that displacing other androgens leaves more of them free. Because the molecule is already a DHT derivative it brings its own androgenic activity, which is why it is judged on how the run feels and on bloodwork rather than on scale weight. The reference half-life is twelve to thirteen hours, so the usual pattern is two doses a day, and urinary metabolites stay detectable for ten to fourteen days and longer.

Dosage & Administration

No dose is approved for sports use, and the medical androgen replacement schedule of 25 mg two to three times daily is not a sports protocol. Community ranges run from 25 mg per day at the low end to 50 mg per day split across two doses, with 50 to 100 mg per day recorded as the advanced ceiling in the checked file and nothing above that supported. Mesterolone does not aromatise, so an aromatase inhibitor such as Arimidex is not part of a Proviron-only plan. It is usually run alongside an injectable, and users comparing dry additions look at Winstrol and Turinabol instead. When it accompanies a suppressive base, recovery is built around that base with Nolvadex or Clomid.

Quality & Authenticity

Each batch is produced under GMP conditions and checked by third-party HPLC, with a Certificate of Analysis held for the batch. Store sealed tablets at room temperature, away from light, excess heat and moisture.

Stacks

Support for a Test Base

Proviron 25 mg twice daily alongside Testosterone Enanthate 250 mg twice weekly for ten to twelve weeks.

Outcome: a drier look and a more androgenic feel while the ester does the work.

PCT: required - recovery is planned around the injectable base, not the tablets.

Pairing with a Dry Oral

Proviron 25 mg daily with Turinabol 40 mg daily for six weeks.

Outcome: leaner gains with no water retention from either compound.

PCT: required - Clomid 50 mg daily for four weeks.

Consult a healthcare professional before any cycle. Where a stack suppresses natural testosterone, PCT is required.

FAQ

Before you ask

Questions, answered

Proviron is mesterolone, a DHT-derived oral androgen. In community practice it is used as a support compound rather than a cycle base: it binds SHBG, adds strong androgenic activity and does not aromatise, so it does not add water. Medical use is androgen replacement, and that schedule is not a sports protocol.

Community ranges start at 25 mg per day and commonly sit at 50 mg per day, split into two doses because the reference half-life is twelve to thirteen hours. The checked file records 50 to 100 mg per day as the advanced ceiling and supports nothing above it. Medically the drug is given as 25 mg two to three times daily for androgen replacement, which is a different context.

The fact sheet rates the hepatic load as low, and the reason is structural: mesterolone is one of the few orally active androgens that is not 17-alpha-alkylated, so it does not rely on that modification to survive first-pass metabolism. It is still a hormone, so bloodwork remains part of any responsible run.

Androgenic effects are the ones to expect: acne, oily skin, increased body and facial hair, and hair shedding in people prone to it. Prostate symptoms and libido changes are reported, and natural testosterone production can be affected. Estrogenic side effects are not part of the profile because the compound does not aromatise, so water retention and gynecomastia are not the usual complaints.

Recovery is planned around the compound Proviron accompanies, because it is used as support rather than as a base. If the run includes a suppressive injectable, the standard post-cycle approach applies with Nolvadex 20 mg daily or Clomid 50 mg daily for four weeks, started once the injectable ester has cleared. A Proviron-only run is unusual and should still be judged by bloodwork.
