Mesterolone 25 mg - British Dragon

Buy Proviron 25 mg tablets by British Dragon at XSteroids. Proviron is the brand name of mesterolone, an oral androgen derived from DHT that is used for libido and support alongside a cycle. British Dragon supplies it as 25 mg tablets, 50 per pack. This guide covers what mesterolone actually is, proviron dosage practice and the side effects that come with an androgenic compound.

Mesterolone is a prescription androgen in several countries, so the information below is educational only.

About Mesterolone by British Dragon

Chemically, mesterolone is 1-alpha-methyl-dihydrotestosterone - a DHT derivative modified so that it survives oral ingestion. Unusually for an oral, it is not 17-alpha-alkylated, and that single structural difference matters: mesterolone is one of very few oral androgens with no meaningful risk of liver damage.

Medically it is used mainly for low testosterone in male hypogonadism, for anaemia, and to support male fertility, though the fertility use is described as controversial. Because it is strongly androgenic and only weakly anabolic, it is used where masculinising effects are wanted rather than for building size.

How Mesterolone Works

No Estrogen, Strong Androgenicity

Mesterolone is not aromatised, so it produces no estrogenic effects - no water retention, no gyno risk from the compound itself. The trade-off is that its activity is skewed toward the androgenic side, which is what drives its side effect profile.

The SHBG Angle

Mesterolone has unusually high affinity for sex hormone-binding globulin, reported in one study at around 440% that of DHT and in another at 82%. That is the pharmacological basis for the way it is used alongside other compounds: it occupies binding sites rather than acting as a testosterone booster in its own right. Anyone expecting it to raise total testosterone will be disappointed - it is not a replacement for a base.

Proviron Dosage and Practical Use

Dosing

Doses used in androgen replacement are 25 mg two to three times per day, which reflects the fact that the half-life is only 12 to 13 hours and bioavailability is low at around 3%. Protein binding is 98%, split between albumin and SHBG, and metabolism is hepatic.

Where It Fits

In practice mesterolone appears as a support compound: some users take it for libido, others through a cycle alongside a base such as Testabol or an oral like Methanabol. It is not a substitute for an aromatase inhibitor - Anastrozole handles estrogen - and not a substitute for a recovery SERM such as Tamoxifen or Clomiphene. Users who want a stronger androgenic injectable usually look at Drostanolone Propionate instead.

Mesterolone Side Effects and Precautions

Because the compound is androgenic, the side effects are those of virilisation: acne, scalp hair loss, increased body hair, voice changes and increased sexual desire. It does not carry the liver risk of 17-alpha-alkylated orals, but it can still suppress natural testosterone when used at higher doses over long periods, and it is not suitable for women or anyone under 18. Blood work remains the sensible way to watch what is happening.
