Product overview

Proviroxyl 25 mg - Mesterolone Oral Androgen, 30 Tabs

Proviroxyl 25 mg is an oral tablet of mesterolone, a DHT-derived androgen supplied as 30 tablets of 25 mg each. Mesterolone is used as androgen replacement in men whose own testosterone is low, and in training the same tablet is run beside a cycle as an androgen that does not turn into estradiol. It is one of the few orally active steroids that is not 17-alpha-alkylated, the modification that gives most oral anabolics their liver load.

How Mesterolone Works

Mesterolone is 1-methyl-dihydrotestosterone, so it binds the androgen receptor directly and is not converted by 5-alpha-reductase. Its elimination half-life is around twelve to thirteen hours, and it does not aromatise at all, which is why it adds no water and no breast tenderness. It also holds SHBG tightly, so a share of the testosterone already in the body is left unbound and free to act. That is why it is used beside an aromatising base such as Testoxyl rather than on its own.

Dosage & Administration

In androgen replacement the tablet is taken as one or two tablets two to three times a day, and in training a common range is 25-50 mg a day, split across the day because of the short half-life. It is not a testosterone base or a recovery drug, so a cycle still needs an aromatase inhibitor such as Arimixyl when estrogen side effects appear, plus a SERM for the weeks after the last injection, Nolvadex 20 mg daily for four weeks or Clomid as the alternative. Follow your prescribing physician's instructions.

Stacks

Androgen Support on a Base: Proviroxyl + Testoxyl

Testoxyl at a steady weekly dose + Proviroxyl 25-50 mg a day, split into two doses, for the length of the block.

Outcome: a dry androgen sits beside the base, so free testosterone rises without extra water or breast tenderness.

PCT: required - the base suppresses natural production; run Nolvadex 20 mg daily for 4 weeks after the last shot.

Estrogen Control Pair: Proviroxyl + Arimixyl

Arimixyl at the lowest dose that holds estradiol in range + Proviroxyl 25 mg twice a day while an aromatising base is running.

Outcome: the inhibitor handles conversion while the androgen keeps libido and density in place.

PCT: required when the cycle includes a suppressive compound; recovery runs with Nolvadex or Clomid.

Consult a healthcare professional before any cycle. When a stack includes compounds that suppress natural testosterone, PCT is required. Dosages reflect common community protocols.

FAQ

Before you ask

Questions, answered

Proviroxyl 25 mg is oral mesterolone, a DHT-derived androgen. Its approved use is androgen replacement in men with low testosterone. In training it is taken beside an aromatising base to keep the androgen side of the cycle dry, because it does not convert into estradiol and it holds SHBG, leaving more testosterone free.

In androgen replacement the schedule is one or two tablets two to three times a day. In training a common range is 25-50 mg a day, divided because the half-life is only about twelve to thirteen hours, and a clinician sets the actual dose. It is swallowed with water, with or without food.

Androgenic effects dominate: acne, hair thinning on the scalp, body hair growth, a deeper voice and a strong rise in libido, plus headache, fluid retention and mood changes. It can lower HDL cholesterol, and higher doses suppress the natural axis. Get medical help for painful or lasting erections, strong abdominal pain or signs of an enlarged prostate.

Mesterolone is not 17-alpha-alkylated, so it carries a lower liver risk than most oral steroids and it has no direct interaction with alcohol. Heavy drinking still adds liver strain and blunts the lipid picture, and the label excludes men with liver tumours, prostate cancer or male breast cancer. Keep intake light and tell your prescriber what you take.
