Product overview

Xeno Labs Proviron 25 mg Mesterolone Tablets

Xeno Labs Proviron is mesterolone at 25 mg per tablet, one of the few oral androgens that is not 17-alpha-methylated. The fact sheet gives it strong androgenic and weak anabolic activity, an elimination half-life of 12 to 13 hours, a low hepatic load and no aromatisation, which together explain how it is used: not as a mass builder, but as a way of keeping the androgen side of a run firm and dry. The same molecule is sold under other labels, including the Dragon Pharma Proviron. Buy Xeno proviron with the batch analysis on file.

How Mesterolone Works

Mesterolone is a DHT derivative that binds the androgen receptor directly, with little of the anabolic push that a testosterone-based compound gives. Its practical effect on a cycle comes from a second action: it attaches to sex hormone binding globulin, the protein that ties up testosterone in the blood, so more of the circulating hormone stays free and usable. Users describe this as a harder, drier look and a firmer libido, which is why the fact sheet lists it as on-cycle support mixed with other compounds rather than a standalone.

Because it does not convert to estrogen, there is no water retention, no breast tenderness from its own action and no need for an aromatase inhibitor on its account. The 12 to 13 hour half-life is short enough that the daily amount is usually split, and the fact sheet notes that it is taken alongside other products partly for that SHBG effect.

Dosage and Administration

There is no approved sports dose. Substitution therapy in the fact sheet is 25 mg two to three times a day, while community protocols sit between 25 and 100 mg per day, split into two doses. Higher figures are not backed by the sources used. Proviron does not replace a testosterone base and is not a recovery drug: recovery belongs to the main cycle and closes with Tamox or Clomiphene.

Stacks

Proviron Alongside a Testosterone Base

A Testosterone ester runs the cycle and Proviron is kept at a low daily amount split across the day for the free-hormone effect.

Outcome: A firmer, drier look and a stronger androgen feel on the same base.

PCT: Came from the main cycle, not from Proviron.

Proviron Plus an Estrogen Control

Where the base aromatises, Arimidex holds estrogen down by bloodwork, and Proviron adds androgenic firmness rather than more estrogen control.

Outcome: Estrogen in range, with the dry look coming from two different directions.

The Dry Oral Pairing

Proviron is often listed with the equally dry Primo S, because neither aromatises and neither is methylated, so the combined load stays modest.

Outcome: Two non-aromatising orals with no added hepatic burden.

FAQ

Before you ask

Questions, answered

Proviron is mesterolone, a DHT-derived oral androgen with strong androgenic and weak anabolic activity. On a cycle it is used as support rather than as a builder: it does not aromatise, it adds androgenic firmness, and it binds SHBG, the protein that ties up testosterone, so more of the circulating hormone is left free.

Substitution therapy in the fact sheet is 25 mg two to three times a day; community protocols run from 25 to 100 mg per day and are normally split into two doses because the half-life is only 12 to 13 hours. There is no approved sports dose, and amounts above 100 mg are not backed by the sources used for this card.

It does not raise production, but it can raise the free fraction. Mesterolone binds sex hormone binding globulin, so less testosterone is locked to that protein and more is available to tissue. That is the mechanism behind the firmer look and libido users report, and it is also why the effect is described as support for a cycle rather than a replacement for a base.

No. Mesterolone is one of the few orally active steroids that are not 17-alpha-alkylated, and the fact sheet labels its hepatic risk low. Any methylated oral taken in the same stack still carries its own hepatic load, so total liver work depends on the whole cycle and not on Proviron alone.

The fact sheet lists virilisation as the main issue: acne, hair loss and voice changes, with women warned off because of how strongly androgenic the compound is. A rise in libido is common, HDL cholesterol tends to fall with androgen exposure, and gastrointestinal irritation is possible, which is usually handled by taking the dose with food.
